    Do you have a girl's outing in a few days, but worried that aunt Flo may interfere with your planned get-together? Tracker Flo uses your previous ovulation cycle (usually ranging from 27 to 35 days) to estimate your next menstrual cycle. It gives you the information you need to plan for your days outside the menstrual period.

    So I used this app for my period And it was great up until my period change and I came on a week early which was perfect for my weekend away because we were planning to get pregnant and my ovulation date was set for a specific day. Well I was on my period a day or two longer so I figured it would probably change my ovulation date. Well my trip was set to be at least about 2 to 3 weeks away and I kept checking the app to make sure and to see if my ovulation date was going to change well it didn’t change it stay the same and make sure that I refresh my app just in case and it stayed the same. Now the day I get to my destinations for my trip is my ovulation day that was on the app that’s what we were depending on. Three days later I go on the app to mark the fact that we made love and the ovulation date changed to the day before I arrived on my trip. Immediately I was upset because it seems as though we may have missed the ovulation day due to the fact that the app didn’t update until after my ovulation date that was set originally. So I deleted the app because of that. It’s very upsetting when you’re trying to get pregnant and your ovulation date just seems to change along with your fertile days changes I just think that that is something that they need to look into I no longer want to use this app.

    So far for me this is the best app. Not only does it tract periods but having to interact with everyone. I was recently ready people's comments about PSM and PMDD. To think that sometimes you go through something and you think it's you alone. So I got to hear other people's stories and it's amazing. Download yourselves Flo app.

    this app is super useful for tracking periods, and has given me mostly accurate predictions so far! it’s been off by a day or two a couple times when i first started using it because it wasn’t adjusted to my cycle yet, but since then i haven’t had any issues. i love the insights where it gives info about my period and the different changes that come along with a period, and i especially love that you can comment anonymously on posts and get help from and give help to the community. by far, my favorite thing about the Flo app is that you can have it give you reminders to drink water, take meds, and weigh yourself if that is something that you’re concerned about! the reminders are super helpful for me as my meds are for adhd, so i need a reminder so i actually remember to take them lol! the only thing that i would adjust is that my water bottle has metric markings, but i live in america, so i have to convert the metric to ounces to track my water because the only way to use metric for water is to switch the entire app over to metric. this isn’t a huge deal because google is a pretty good converter but it’s just something that i’ve noticed. overall, this is a great app and i’ve recommended it to friends and family, and now i’m recommending it to you!

    This is honestly the best period tracker app I've used. I have tried others but they weren't good. I've been using Flo since May of 2018. I also subscribed to the yearly premium. I really enjoy this app and recommend it!

    Decent for a period app. Does it's job. However, it never really hit the mark when it came to predicting my period or ovulation. It was either a week too early or a few days too late, according to the app. I used to enjoy the secret chats, but now they're littered with kids begging for likes instead of insightful and meaningful conversations. Additionally, when an app is constantly asking you to buy premium every moment you're on there, your userbase isn't going to enjoy it as much.
  • Definitely the best period app. Mar 19, 2020

    After I got my first period I used the same app for years to track it. It never predicted my period right. For the longest time I just figured I was super irregular as many girls are when they start there period, but eventually I realized It said I was consistently late by approximately the same number of days every cycle. I just dealt with it for awhile. When I finally decided to check for a better period tracking app I found Flo. This app is SO MUCH BETTER!! It usually predicts my period pretty accurately, sometimes spot on. When my cycle shifts it always makes adjustments and often becomes more accurate. I also love that it doesn’t mark your period late until A certain number of days after your cycle was supposed to start (I think 5, which is the “official” number of days that make a period considered late. It doesn’t just mark it late when your period doesn’t start the day it was predicted to. I was especially impressed when I missed a period after my wisdom tooth surgery and when I logged my next period the predictions continued to be accurate immediately after. It seems like the developers did a great job on the actual software as well as put lots of thought, research, and expertise into it. It’s a great app!!

    Good app to track you period but if you want any information you have to pay 7.99 a month. Which I think is unfair. Everyone with ovaries should have the chance to learn at least some information. Having your period isn't something we choose to have it's a natural cycle that happens to us every month. So limiting the information to only people who can afford it is kinda sick in my opinion.

    I’ve had Flo in the past and loved it. I didn’t have a phone for a year so I just recently got the app again and noticed a lot of changes, including that some features are only available through a payment. The payment is only around 14$ for the entire year. I don’t think that’s so bad but if it’s out of budget I understand. The features on the free trial are pretty awesome so far, it’s like having access to a gynecologist because the information you give about your period has so much feedback. It’s really surprising what the app tracks and the amount of feedback you get about symptoms, tips / tools, workout ideas, food recommendations, yoga, meditation, and self- assurance. I wanted to take the time to write a review because I was really hesitant to redownload the app with the reviews talking about payments but I’m glad I did and it appreciating the free trial so far. If you’re unsure try the 1 month free trial and see how you like it. Bonus for the awesome private community conversations that are available to everyone, so that you’re able to anonymously speak with other women/ girls on the app and freely ask questions or help respond to others. It’s just really awesome. I appreciate the app

    Used to be a better app, before the updates 😏 full of adverts and most of the stuff you can't actually get on/read about, without a paid membership. I input my "dates" on a new device and noticed that this app gives different stats and predictions on 2 different devices despite the input info being the same. Amazing, easy to read and understand the info given but this cannot be used safely for people using natural family planning. Excellent as a rough guide or just to keep track yourself
  • Amazing but needs a touch. Sep 13, 2017

    By simply0413
    Don't get me wrong, Flo is amazing and you'll never use another app after you download this but it could use a few touches. The one idea I have isn't really important but if you want to have more fun with the app you should also have the choice of using your own photo for a background picture. Doing this would make it a little more fun along with being able to choose the color of the circles or bubbles. Also, it would be cool if people could make their own articles for everyone to read but make a separate column you can click on, incase viewers don't want to read other people's. And lastly, the articles usually talk about tampons. Not everyone wears them including me. It would be great if you could tell everyone how they work and if it hurts. I personally am really sensitive about "down there" and it would be great to know what it's like. Or even talk more about pads. Right now I read things I can on the internet and see how to insert them and everything. But I rly think sticking something up there is really nasty. Again just my opinion. But overall this game is really good. If it was just a little more fun and fit for everyone I would be giving it 5 stars. But hopefully something I said can come true.

    Don't bother with premium. The 'insights' never go beyond the most basic, super obvious observations, things like 'tips to ease cramps - use a hot water bottle' 🤦‍♀️ I've had it for almost a year and it's totally useless for anything beyond tracking your period. I only signed up because of the constant barrage of notifications that led nowhere other than a promt to subscribe. They say you can turn off notifications but that also cancels out the ones that tell you when your period is due 😒
  • Not a fan of new format Jul 23, 2021

    By mallalalalalalalalala
    I used to love flo. I’ve been using the app since my junior year of high school (I’m now a senior in college). I appreciate how I’ve been able to track my period through the years, as it’s been enormously helpful to my overall health, well-being, and awareness of my body. That being said, I have really struggled with the new updates that flo has undergone. Not only has the app become significantly less user-friendly, but the constant push to “go premium” has really negatively impacted my experience. I understand why they have a premium option, and I respect that it is there, but what I don’t respect is how I’m constantly being mislead in order to be trapped into signing up for a premium subscription. I find it really irresponsible that women who don’t want to pay for this app, will be given insights about their menstrual health, only to find out that they can’t have access to the information behave they don’t have an account! I used the chat feature a few times before, and it’ll leave me responding to chats for about 5 minutes, and right before they give me an answer about my health, they say I need to subscribe! It’s honestly cruel that an app meant to help women feel more secure about their health, is constantly misleading them like this, or trying to buy their desire for basic health info! Most of which can be googled, btw. I’ve really loved using flo, but am honestly considering shifting gears if things don’t change soon.

    So this app used to give me insights that weren't on premium. Now any insights it offers have to have premium to get them. Like absolutely nothing is free. I used to really like this app. But that has been super disappointing. Planning on switching to something different now.
  • Extra features only available with premium Oct 2, 2020

    By kathynicole
    I originally downloaded this app to track my period and my symptoms. I do still like it for that, but I also really loved when more features were added such as giving helpful bits of info about the whole cycle. This info wasn’t always that helpful for me because most of it I knew already, but I do think it’s helpful for younger people. I didn’t learn much about the menstruation cycle in school, and I just can’t imagine much has changed. It was also helpful that they gave you tips seemingly based on the symptoms you plugged in. However today I went to log my symptoms and noticed they added in stories on why we get cramps, etc., but they are all only available to premium users. And when I went to the screen that used to have helpful articles, mostly all of the information is locked for premium users. This is all information that should be provided for free. Now kids are still going to have to wade through inaccurate information on the internet because apps like this are charging for the most basic information. I understand that you need money to survive, but information menstruation shouldn’t only be available to people with money. Also you would think they could get a moderator for the chat rooms or a professional to help answer questions, but no. So the chat rooms and answers are inaccurate and overrun with teens who don’t know anything because apparently female anatomy is only available to people with money. It’s such a shame.
  • Too many ads Apr 12, 2021

    By Jamieeeeeee21
    I only want notifications that tell me when to anticipate my menses start date or ovulation, but I constantly get notifications like “Feeling frisky today? Your hormone levels are up!” “Set up a workout today” “It’s normal to feel down when your hormones drop” and other inappropriate statements that are embarrassing to receive when I am showing a work colleague something on my phone. I reported the issue to Flo and they said I had to turn off notifications altogether! It’s ridiculous how we cannot filter what we want to be notified of. Also, at the doctor’s I was asked the first date of my LMP. That’s what Flo is for. It took a full minute to open the app and click out of the annoying in-app pop ups that try to get me to use their features when all I wanted to do was go to my calendar. I don’t want to speak to your health advisor or whatever else you want me to do. I want a simple, unmessy, easy app to track my period. Lastly, I’ve been having issues opening the app and all I see is a huge ad saying “87% off Flo premium. Click next” and there is NO X at the corners to get away from the page. The only thing to click is “next” but I don’t want your premium. I have to close the entire app and reopen it to get the ad to disappear. Your app has a lot of people using it but it seems to be devolving into something sloppy and profit-hungry. I miss the days where it was a no-hassle, modest period tracker.

    I have been using this app for several years to track my period and ovulation. It's usually off every now and then but I found a better app that accurately predicts my periods and ovulation. I think the algorithm could be better. The ovulation dates they gave me my last cycle was just way off. That was the last straw.
  • Great for period tracking only May 30, 2019

    By lauritaGarcia
    I downloaded this app to track my periods, was great for that and plenty of little helpful insights/articles on the feed.. I used it to help conceive as well. Once I actually became pregnant and switched to “pregnancy mode” the little helpful insights diminished to almost none, maybe one every few weeks.. what would frustrate me also would be when I would click on the “For You” and it would show an insight article but then disappear before I got the chance to click on it. (Happened about a 100 of times on different occasions.) also the app doesn’t really have any symptoms tracker differentiations for the pregnancy mode... which seems kind of bizarre. Another thing is that in pregnancy mode it doesn’t say anything about the development of the baby at however many weeks you are. Not even a brief little description of what’s going on in your body at this time or a brief description of the development changes your baby is experiencing.. nothing at all.. I’m a first time mom so I use (5) different pregnancy apps to kind of bring all the information together, given that not all say the same thing or some say things others don’t and/or are more informative. I find myself using this app less and less as it isn’t very helpful in the pregnancy mode. I am currently 27 weeks so I’ve used it from the very beginning and nothing is getting better about it.. hopefully this review is helpful

    It WAS a 5-star app. I have been using this app since late 2016 & it has my cycle down to a science! I can be somewhat irregular & spacey so having the app is a godsend. Over the last year, they have become increasingly persistent w/pushing premium & today is nearly the final straw. I had to click through 20+ ads (all for flo) to be able to log my period, on top of emails, & push notifications (which I finally turned off). Saved my data & will be deleting the app if they dont make changes soon.

    Decent app for tracking periods but the targeted marketing needs work. As someone with infertility issues that I have logged in the app, it feels insentive getting notifications about "PMS or early pregnancy". Feels like a slap in the face. Turned off most notifications now but considering the user base, there should be more functionality to not be constantly reminded that you aren't pregnant.

    I've already raised my concern last Aug 22. Tho someone replied, the problem is still not solved until today. There's nothing in discover tab and no stories. I'm not a premium user. But when i was using an iphone there was no problem. Now that i switched back to android, this happened. I tried uninstalling and installing again. Will edit my rating again once my concern is solved.

  • 2+ Year User and still Loving it ! Jul 23, 2019

    By darion smith
    I have been using this app for awhile now and have been very dedicated to tracking my body's cycle. With this app I avoided pregnancy successfully for 2 years without hormonal birth control by working around my fertility rhythm using the information Flo provided. The longer you use it, the more accurate it it becomes. I think it is essential to track our menstruation. Apps like these can be life changing for women; Reproductive knowledge is empowerment for women. I always enjoy the updates and community sections. Tried other period trackers but I always just come back to Flo because I enjoy the aesthetically pleasing interface and ease of use. This is an app that gets better with time. Only until recently have I desired more; after giving birth I'm breastfeeding of course, and that can often cause you to go a while without a period. I wish there was a way to log this information as I await to have my cycle again, in a similar manner to flipping a switch for the pregnancy mode. When you look at past data, pregnancy shows up as yellow days in your year calendar. Just a thought. Could continue to aid in accurate predictions if this info was considered.
  • I use it everyday Apr 19, 2019

    By mimi.w_1013
    I just got this app yesterday and already love it. It’s so easy to use and very informative. Setting up your period (or pregnancy) might be a little confusing at first but once that’s done, you’re fine. I love how precise they try to be and get to know you with surveys (they’re optional). I also love how they give you all different articles to read about (romance, hygiene, body, clothing, exercise, etc.). You also get to chat anonymously with other women and girls - we really help each other out. I could write so much more but don’t want to take up too much time😂. I tried other apps and like this one the best - I would definitely recommend it!! I just finished my period so I don’t know how accurate this will be but based on my calendar at home, it’s right on track. This is the app to use! No app will be perfect, but this is the way to go - i can’t even say how much I love it (weird to be saying about a period app haha!) I’ll update my review once I’ve gotten my next period to see how accurate they are. One thing I don’t like is that they limit how many words/how long your comment can be which gets very annoying so if they can change that, it’d make the app even better.

    I’ve had this app for a few years now and can honestly say I love it. It’s helped me with so much, including with figuring out how my medications affected me, where before I was so confused with what was going on. Watching this app evolve has been so cool, and I used to have a subscription in the earlier days, which was super handy. I also just tried the free trial of the newest premium version, which is absolutely amazing, and provided me with so much information that I actually feel somewhat educated on my body and how it works. I am a newfound broke college student and am bummed I don’t have the funds to pay for it right now (which I believe is an essential part to keeping this app running, because though we should have the right to free access about the health of our own bodies, I know I can trust this app based on the knowledge that hundreds of hours of work have been put into this by real doctors, instead of finding less trustworthy and sometimes misleading information floating around the internet). I will continue to be loyal to this app and will also hopefully soon be able to take advantage of the healthcare advice again!

    Before, I would always keep the details of my sex life, menstrual cycle, and other feminine problems to myself. After Flo, I feel so much more secure and content with all of the aforementioned issues. The app is well-designed and visually pleasing, as well as easy to use and practical in those uses. Not only can you track your period with Flo, you can also access a community page to share stories, take surveys, and read articles. The period tracker itself is very accurate for me and is usually always on point. The period tracker also gives you the details on your ovulation cycle and such, which gives me a sense of security and preparedness. While I don’t use this feature of the app, there is also a pregnancy mode which can track your pregnancy’s phases and tell you about said phases. I’ve come to love the app and it quite honestly bests all of the other period tracker apps I’ve tried. Flo is great for any woman who loves planning and organization, or any girl looking for advice on her first experiences. The community is accepting and welcoming, and all shared stories are anonymous for those who want to vent. Overall, a wholesome app with a feel-good vibe. Definitely a keeper for me.

    So far, the Flo app has been very informative. This app helps me to understand my reproductive health much more than a one hour visit to my ob/gyn. Not only does this app have a menses tracker but it also discusses mental health and the importance of getting help if your in distress. Which is incredibly important for girls and women alike. Now if there were only an app for men that is informative about their reproductive and mental health, both sexes will be more comfortable in their bodies.
  • It’s nice but... Feb 23, 2019

    By Naughty nixon
    So I used this app for my period And it was great up until my period change and I came on a week early which was perfect for my weekend away because we were planning to get pregnant and my ovulation date was set for a specific day. Well I was on my period a day or two longer so I figured it would probably change my ovulation date. Well my trip was set to be at least about 2 to 3 weeks away and I kept checking the app to make sure and to see if my ovulation date was going to change well it didn’t change it stay the same and make sure that I refresh my app just in case and it stayed the same. Now the day I get to my destinations for my trip is my ovulation day that was on the app that’s what we were depending on. Three days later I go on the app to mark the fact that we made love and the ovulation date changed to the day before I arrived on my trip. Immediately I was upset because it seems as though we may have missed the ovulation day due to the fact that the app didn’t update until after my ovulation date that was set originally. So I deleted the app because of that. It’s very upsetting when you’re trying to get pregnant and your ovulation date just seems to change along with your fertile days changes I just think that that is something that they need to look into I no longer want to use this app.
  • Amazing but needs a touch. Sep 13, 2017

    By simply0413
    Don't get me wrong, Flo is amazing and you'll never use another app after you download this but it could use a few touches. The one idea I have isn't really important but if you want to have more fun with the app you should also have the choice of using your own photo for a background picture. Doing this would make it a little more fun along with being able to choose the color of the circles or bubbles. Also, it would be cool if people could make their own articles for everyone to read but make a separate column you can click on, incase viewers don't want to read other people's. And lastly, the articles usually talk about tampons. Not everyone wears them including me. It would be great if you could tell everyone how they work and if it hurts. I personally am really sensitive about "down there" and it would be great to know what it's like. Or even talk more about pads. Right now I read things I can on the internet and see how to insert them and everything. But I rly think sticking something up there is really nasty. Again just my opinion. But overall this game is really good. If it was just a little more fun and fit for everyone I would be giving it 5 stars. But hopefully something I said can come true. To Whom Ever It Regards, - Unknown☺️

    By Thisislexi2
    The reason I downloaded this app was because I have fairly irregular periods. They have always been irregular, but I discovered that I have hypothyroidism which contributes greatly to irregular periods. I am also breastfeeding and have been breastfeeding for 18 months. I do notice that when I take my thyroid medication my periods become a lot more predictable and more normal. So, with that being said I did not expect this app to be spot on for me. I am just not one of those women who have a really predictable cycle. If you have a predictable cycle than this app will work great for you!! It tells you ovulation days so you can try (or avoid) getting pregnant. It reminds you when your period is due which is nice. Since my periods aren’t regular it took about 4-6 cycles to actually get the app to correctly predict my periods which is understandable. It’s important to log all your symptoms because that’s how it tells which phase you are in. This month it said I was supposed to start, but when I updated my symptoms, it changed the date I was due for my period. My period actually came 3 days before it was “due” but still, that’s pretty good guessing with someone who has irregular cycles. I do also love that they have articles you can read that educate you about your body. 4.5 stars.

    Decent for a period app. Does it's job. However, it never really hit the mark when it came to predicting my period or ovulation. It was either a week too early or a few days too late, according to the app. I used to enjoy the secret chats, but now they're littered with kids begging for likes instead of insightful and meaningful conversations. Additionally, when an app is constantly asking you to buy premium every moment you're on there, your userbase isn't going to enjoy it as much.

    Good app to track you period but if you want any information you have to pay 7.99 a month. Which I think is unfair. Everyone with ovaries should have the chance to learn at least some information. Having your period isn't something we choose to have it's a natural cycle that happens to us every month. So limiting the information to only people who can afford it is kinda sick in my opinion.

    Used to be a better app, before the updates 😏 full of adverts and most of the stuff you can't actually get on/read about, without a paid membership. I input my "dates" on a new device and noticed that this app gives different stats and predictions on 2 different devices despite the input info being the same. Amazing, easy to read and understand the info given but this cannot be used safely for people using natural family planning. Excellent as a rough guide or just to keep track yourself

    It's a good app to stay on top of things...however you cannot add that you have an IUD as a form of birthcontrol and my app freaked the first month after I had got it cause I was late (gave me a notice that k could be pregnant) and my period lasted 3 weeks. My cycle has also been irregular since getting it and it keeps telling me to see a doctor for XYZ reasons. I have an IUD thats why its so off.

    By Candy Cicada
    It's great and everything, but the only things I don't like about Flo are the insights, stories, and secret chats not loading for me and the fact that I need premium in order to do certain things. Not to mention whenever I download Flo on another device, my menstrual cycle histories and predictions don't even match what's on the device I first downloaded Flo on. Now Flo's starting to suck. As soon as I downloaded the app, my symptoms and moods were erased. Smh. I wouldn't recommend this app.

    By Jessica
    I've been using this app for 5+ years, which makes it difficult to try out different cycle trackers since all my data is here. It used to be much simpler, but in recent years they have bogged the app down with lengthy animations, pop-up messages, and constantly asking me to try other features of the app. I am unable to find a way to turn any of this off. If you want all the extra hoopla, then great. If you want a simple cycle tracker, I would look elsewhere.
  • Close to great, but missing the mark for me Aug 23, 2021

    By marianne6699
    I was very excited about downloading Flo to take more ownership over my cycle & gain resources / insights regarding my intimate health. However as soon as I tapped over into the “secret chat” feature, I found an overwhelming presence of ideological (predominantly Christian) conversations. I know that spirituality and sex lives can be tightly connected, however as someone who doesn’t identify with organized religion, it felt like I’d just arrived to the wrong brunch party. This also immediately made me skeptical of the information being shared within the app. I’m a VERY strong believer in comprehensive sex education, which is commonly seen as being at odds with Christianity in this country—is this app actually balancing science and religion? After looking at their extensive board of medical professionals, I’d like to believe so but I’m still highly skeptical. This is where I also learned that the app was founded by two men (tech entrepreneurs), who (let’s face itttt) probably only care about women’s health in so far as $$$. All in all I wish I hadn’t paid for this app and had opted for a free alternative, as I don’t think the secret chat feature will be useful to me and I have skepticism issues regarding their approach to science / commitment to women’s well-being. The UI is beautiful, I’ll give it that.
  • Not a fan of new format Jul 23, 2021

    By mallalalalalalalalala
    I used to love flo. I’ve been using the app since my junior year of high school (I’m now a senior in college). I appreciate how I’ve been able to track my period through the years, as it’s been enormously helpful to my overall health, well-being, and awareness of my body. That being said, I have really struggled with the new updates that flo has undergone. Not only has the app become significantly less user-friendly, but the constant push to “go premium” has really negatively impacted my experience. I understand why they have a premium option, and I respect that it is there, but what I don’t respect is how I’m constantly being mislead in order to be trapped into signing up for a premium subscription. I find it really irresponsible that women who don’t want to pay for this app, will be given insights about their menstrual health, only to find out that they can’t have access to the information behave they don’t have an account! I used the chat feature a few times before, and it’ll leave me responding to chats for about 5 minutes, and right before they give me an answer about my health, they say I need to subscribe! It’s honestly cruel that an app meant to help women feel more secure about their health, is constantly misleading them like this, or trying to buy their desire for basic health info! Most of which can be googled, btw. I’ve really loved using flo, but am honestly considering shifting gears if things don’t change soon.

    So this app used to give me insights that weren't on premium. Now any insights it offers have to have premium to get them. Like absolutely nothing is free. I used to really like this app. But that has been super disappointing. Planning on switching to something different now.
  • Too many ads Apr 12, 2021

    By Jamieeeeeee21
    I only want notifications that tell me when to anticipate my menses start date or ovulation, but I constantly get notifications like “Feeling frisky today? Your hormone levels are up!” “Set up a workout today” “It’s normal to feel down when your hormones drop” and other inappropriate statements that are embarrassing to receive when I am showing a work colleague something on my phone. I reported the issue to Flo and they said I had to turn off notifications altogether! It’s ridiculous how we cannot filter what we want to be notified of. Also, at the doctor’s I was asked the first date of my LMP. That’s what Flo is for. It took a full minute to open the app and click out of the annoying in-app pop ups that try to get me to use their features when all I wanted to do was go to my calendar. I don’t want to speak to your health advisor or whatever else you want me to do. I want a simple, unmessy, easy app to track my period. Lastly, I’ve been having issues opening the app and all I see is a huge ad saying “87% off Flo premium. Click next” and there is NO X at the corners to get away from the page. The only thing to click is “next” but I don’t want your premium. I have to close the entire app and reopen it to get the ad to disappear. Your app has a lot of people using it but it seems to be devolving into something sloppy and profit-hungry. I miss the days where it was a no-hassle, modest period tracker.
  • Great for period tracking only May 30, 2019

    By lauritaGarcia
    I downloaded this app to track my periods, was great for that and plenty of little helpful insights/articles on the feed.. I used it to help conceive as well. Once I actually became pregnant and switched to “pregnancy mode” the little helpful insights diminished to almost none, maybe one every few weeks.. what would frustrate me also would be when I would click on the “For You” and it would show an insight article but then disappear before I got the chance to click on it. (Happened about a 100 of times on different occasions.) also the app doesn’t really have any symptoms tracker differentiations for the pregnancy mode... which seems kind of bizarre. Another thing is that in pregnancy mode it doesn’t say anything about the development of the baby at however many weeks you are. Not even a brief little description of what’s going on in your body at this time or a brief description of the development changes your baby is experiencing.. nothing at all.. I’m a first time mom so I use (5) different pregnancy apps to kind of bring all the information together, given that not all say the same thing or some say things others don’t and/or are more informative. I find myself using this app less and less as it isn’t very helpful in the pregnancy mode. I am currently 27 weeks so I’ve used it from the very beginning and nothing is getting better about it.. hopefully this review is helpful

    It WAS a 5-star app. I have been using this app since late 2016 & it has my cycle down to a science! I can be somewhat irregular & spacey so having the app is a godsend. Over the last year, they have become increasingly persistent w/pushing premium & today is nearly the final straw. I had to click through 20+ ads (all for flo) to be able to log my period, on top of emails, & push notifications (which I finally turned off). Saved my data & will be deleting the app if they dont make changes soon.

    Decent app for tracking periods but the targeted marketing needs work. As someone with infertility issues that I have logged in the app, it feels insentive getting notifications about "PMS or early pregnancy". Feels like a slap in the face. Turned off most notifications now but considering the user base, there should be more functionality to not be constantly reminded that you aren't pregnant.

    I've already raised my concern last Aug 22. Tho someone replied, the problem is still not solved until today. There's nothing in discover tab and no stories. I'm not a premium user. But when i was using an iphone there was no problem. Now that i switched back to android, this happened. I tried uninstalling and installing again. Will edit my rating again once my concern is solved.

    Absolutely loved this app.. and thought it was so helpful when you starting adding insights and secret chats etc.. but now I can't even find 1 full article to read without being told to 🌟 unlock premium 🌟 Really sick of every article being locked and Flo Health assistant chat being cut short every time. I know apps cost money, but from someone who has used this for years, it's a bit of kick in the butt really. Disappointed.
  • Disappointment as the app “grows” Aug 5, 2021

    By 3457811946
    I understand that Flo is run by A LOT of people that need to be paid so while I understand that premium is needed in order to make their ends meet to pay everyone on board. I think there are a few select things they could do to for people who can’t afford premium. Firstly, go back to letting us see more than just two months predictions of our menstrual cycle. I don’t understand why that had to be limited if it doesn’t really seem like a “premium feature”. Cycle predictions, at this point, and along with period tracking, seem to be the only TRUE free features of this app up until this update. I feel like next, “My daily insights” are also going to be a Premium Feature and I feel like that would be overly selfish of a “free” app. Another thing y’all could do is provide SOME free content of the Insights we currently have to pay to see. Like a preview if you will. This would have been a great app had it stayed accessible to teens barely getting their cycle. Women’s health is hardly talked about and a lot of girls end up feeling insecure about themselves because they see changes and feel things no one wants to talk about and a lot of that is seen here in this app. While it is a shame that Flo had to start charging, it is understandable but work on making important information accessible, please!

    By Leanne
    Don't bother with premium. The 'insights' never go beyond the most basic, super obvious observations, things like 'tips to ease cramps - use a hot water bottle' 🤦‍♀️ I've had it for almost a year and it's totally useless for anything beyond tracking your period. I only signed up because of the constant barrage of notifications that led nowhere other than a promt to subscribe. They say you can turn off notifications but that also cancels out the ones that tell you when your period is due 😒
  • Extra features only available with premium Oct 2, 2020

    By kathynicole
    I originally downloaded this app to track my period and my symptoms. I do still like it for that, but I also really loved when more features were added such as giving helpful bits of info about the whole cycle. This info wasn’t always that helpful for me because most of it I knew already, but I do think it’s helpful for younger people. I didn’t learn much about the menstruation cycle in school, and I just can’t imagine much has changed. It was also helpful that they gave you tips seemingly based on the symptoms you plugged in. However today I went to log my symptoms and noticed they added in stories on why we get cramps, etc., but they are all only available to premium users. And when I went to the screen that used to have helpful articles, mostly all of the information is locked for premium users. This is all information that should be provided for free. Now kids are still going to have to wade through inaccurate information on the internet because apps like this are charging for the most basic information. I understand that you need money to survive, but information menstruation shouldn’t only be available to people with money. Also you would think they could get a moderator for the chat rooms or a professional to help answer questions, but no. So the chat rooms and answers are inaccurate and overrun with teens who don’t know anything because apparently female anatomy is only available to people with money. It’s such a shame.

    I have been using this app for several years to track my period and ovulation. It's usually off every now and then but I found a better app that accurately predicts my periods and ovulation. I think the algorithm could be better. The ovulation dates they gave me my last cycle was just way off. That was the last straw.

    Everything is premium now nothings free not even the sligest information. Pure bollocks. I have been using Flo for soo many years, quite disappointed, uninstalling here, whats the point if nothing can be accessed. If there was a lower rating I definitely would. Do not waste your time installing, there isn't any information free, not even about your menstrual cycle.
  • New update ruined it.. Sep 19, 2020

    By GeekyGirl007
    There should really be a way to turn off virtual assist and my daily insights. Some of us came to this app because it was clean and simple, all these new updates and features are ruining that. It’s getting more and more intrusive and cluttered with every update. I don’t need or want all this crap on my screen. If I could toggle it off it’d be great but they give you no options, just shove all this stuff in your face. Why can’t anything be simple? Why do we need advanced AI and health stories on the front page? We don’t! Just a simple app that tracks and predicts our cycles and does it well. Please get rid off all this extra junk or at least give those of us who don’t want it a way to toggle it off. I hate this app now and will be finding a new one. To the developers- please don’t ask me to contact you for a solution. It seems to be your canned answer to every negative review and I will not be contacting you. If there is a solution to this issue or you have future plans to fix this issue, please just let me know here so the whole community can see it too. Nothing is going to be fixed in this situation by me contacting you. You used to have amazing customer service and really care about your users needs. Not anymore, there hasn’t been a genuine reply to any users feedback in a long time. This use to be a great app with caring devs behind it, but I can’t say that is true anymore sadly. Zero stars.

    Mostly have to pay to see what's up. For reals. I go into insights to maybe see if I can read up on symptoms and 95%or more is locked because I don't pay for premium. I've been using this app for awhile, I loved it until they took the information away. I'm on the hunt for a period tracker that will actually help me learn some things that coincide with my period. This was the best free app for tracking my period, now it's a pay app if you wanna actually LEARN about your body. Shame. 😥

    Loved this app until I subscribed to premium and now it won't let me unsubscribe. I've contacted support multiple times and they say they'll help but then they never respond. I just need to know the steps on how to unsubscribe through the web since I didn't get it in the app!! I would like to deactivate my account!
