  • love it! Jul 24, 2018

    By Ricecake2003
    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!

  • 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.

    Used to be very good, since the premium thing started, everything is now premium which sucks and it's quite inconvinient. That's not reason why I'm writing this review. I use the calendar widget, for obvious reasons: I can see when I'll get my period. Over the past few months the widget however has a VERY annoying problem: no matter what day it is, the next day is always my period day. To solve it I gotta open than close the app, but after a few hours, it happens again. Please take a look at it.

  • Definitely the best period app. Mar 19, 2020

    By Fairysparkles6
    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!!

    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.

    No, I am really fed up with contacting customer service from within Flo app. This is useless. Not even a single issue I complained on is fixed, I am dissatisfied. I do not recommend Flo. And no. I will not continue my premium, it is no different from free. Even premium is full of nagging ads. No special features, not even a setting to make my week starting from Monday. Limited and full of bugs.

    Most features that stood out against other period trackers aren't free anymore. Even more concerning when some insights say you logged something that may be of concern but when you click on it, you have to pay premium to see it. The ads for premium come up constantly. With the basic user, it's just the same as any other period tracker so keep that in mind unless you don't mind paying for premium.

  • 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.

    The initial free version of the app was adequate, nothing amazing but served a purpose. Out of curiosity I subscribed to premium when there was a special offer and I was really disappointed as far as I can tell the only difference is you can now see "daily insights" which are essentially really rubbish mini articles that lack information and pointless bothering to read. I rarely review apps but I felt so ripped off I didn't want anyone else to make the same mistake. Don't waste your money!

    I've been using Flo to track my period for four years. I used it to track my whole pregnancy. The experience is completely ruined by the intro of premium. I used to get helpful free information about my cycle, but now it wants you to pay a monthly fee just to access any information at all. Isn't it hard enough for women to access accurate information about women's health already? Flo used to be for women, now it's just for money. Completely corrupted by premium. Don't download, and don't buy.

  1. Keep track of your entire cycle from beginning to end! Log all your symptoms so you know what you can expect the next time around
  2. Keep track of your physical activity to see how it might affect your cycle now and in the future
  3. View your most fertile days of the month so you know how best to plan for pregnancy

  • Currently On a Free Trial Sep 18, 2020

    By Milia G
    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

  • 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.

  • 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☺️

  • Pretty good Nov 18, 2017

    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.

  • Good, but having issues (now MORE issues?) Apr 21, 2020

    By C_Turtles
    UPDATED CORRECTION: My ovulation week (which happened weeks ago) jumped up an entire week too for. So now my period and ovulation dates are changing for seemingly no reason. This has never happened before. I understand the developer’s response, but I’m still not sure if you’re understanding the issue or if I’m failing to see something. Like I said, I’ve never had issues with this EVER, so why is every single thing changing. My period date. Changed over 6 times in the last few days, and so did my ovulation too. This makes no sense. I never had issues with this before, but this month, the day on when my period is going to start keeps changing. Every day it gets bumped up to the next day. First it said the 18, then 19, and now it’s up to the 21st. I don’t know if there’s an error occurring in the calendar or what, but it’s really annoying and confusing. I can’t tell what day is the correct day for my period to start, and now I’m worried everything else is wrong or the dates are offset (like for ovulation, as an example). Note: this has nothing to do with periods being late, as this is many days prior to when my period should even start.

  • Almost Perfect Jun 16, 2020

    By Bikerchick3008
    I love this app, and all the options it allows. Especially the symptoms it allows you to add day by day, it really helps me figure out my cycle and how my body is responding to my life. The app is relatively easy to use, and pretty customizable. The two main things that I wish to see updated in this app, is the option for the app to tell you how many days late you are. Currently if you are late, instead of reflecting that, it just keeps pushing your "expected period" date to the next day. I have been trying to find a way to see if i'm missing a setting to add this feature but so far no luck. I really like that feature on other apps so hopefully Flo adds it. And number two and perhaps the most important, I wish it allowed you to add a PREVIOUS pregnancy. It allows you to go through add previous periods so it can give you an accurate cycle length/prediction, however no options to add previous pregnancies which I think would prove very helpful to the app being able to predict future periods/pregnancies. Also I would like to have the option to add a personal picture instead of just the avatar but it's not really that big of a deal. All in all I love this app and highly recommend it!

    I downloaded this app a couple of years ago to keep track of my cycle and symptoms. I still think it works, but there are some bugs and downsides. - The widget is almost never synchronised with the app and when nearing my period the widget keeps showing the symptoms I applied to the same days just the month before. - Sometimes the reminder for the oral contraceptives doesn't pop up at all. I haven't figured out when, but it makes it hard to trust the app and can potentially be really dangerous.

  • Not woman-owned, Paywall is a slap in the face Jul 9, 2020

    By Aydee221
    I’d been using Clue up till now. I read that Flo had some additional tracking options (such as indicating when you change your chosen period collection method and, if applicable, how much you collected). They must have still been rolling out the feature because I didn’t have it or find a way to enable it. But the paywall is why I’m writing this review. Literally everything except tracking your period and a generally unhelpful and unmonitored community chat is locked behind that $50 subscription. If I track a symptom consistently and the app recommends an article to me, just let me read it. Or at least a portion of it. Don’t immediately hit me with the ad to subscribe. The frequency of that ad alone is enough to make me not want to subscribe. And don’t get me started on the community chat. It NEEDS to be moderated. There is some straight up harmful garbage there (not all but enough). I also did some digging and the app is not woman-owned or founded (which is important to me). Some entrepreneur guy founded it and as far as I can tell they don’t use revenue from the app to support any women’s causes. I think I’ll be going back to Clue, where at least it’s designed by women, for women, and has a more thoughtful paywall.

  • 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

    This is a pretty great period tracker. It's easy to track important symptoms and period changes. EDIT - I am so disappointed in what the developers did with this app! It was so great to be able to learn about symptoms you entered, but now you have to pay for premium just to see the insights. You can't do anything beyond track your cycle and log symptoms now unless you pay for it. This used to be my fave tracker but now it's just another heartless money grab. So so disappointed.

    This app used to be perfect. Now it's useless and full of ads. I only want to get notifications on my period and not insights I am not interested in. Also everytime I open the app I have to close all the annoying premium pop-ups just to finally see when my period starts! I understand that the developers want to make money from it but they can make it in a more peaceful way. I am going to uninstall it.
