    I got clue because I was having a difficult time remembering to track my period on my messy calendar. When I began using it, I found that it was very easy and straightforward to use with customizable tracking options besides just the period bleeding itself like emotional state, pain, ovulation, sleep, digestion, etc. I just wish that the exercise tab had more options to choose from. After using it for a few months, the app had enough data to show me patterns during my cycle which were very enlightening to me. By recording my daily experiences and looking at the generated patterns and predictions I have been learning a lot about my body that I was previously unaware of before. But my favorite thing about discovering clue is that the company provides articles on women’s reproductive health for free on many different issues, and that these articles are fact-checked and use peer-reviewed journal studies as their sources (and list the sources so I could look them up myself if I wanted to). These articles provide me with information I otherwise didn’t have access too or was too embarrassed to ask about like the many birth control options available, how they work, and their pros and cons. Definitely more than just a period tracking app.

    This app is literally the best period tracker I’ve ever had. I started using it just over a year ago(ish), and it’s truly been helpful. I added in my past periods from another app and that helped a lot with it being able to always be spot on for my days. One thing I would recommend, is having a “Notes” section for days. I feel like that would be nice because I can remember why I didn’t take my BC (birth control) at a certain time and I can work on being more on time with it. It’d also be nice to keep track of other things in there, such as “my cramps were this bad today because xyz.” And instead of using just the cramps button, I can make a note of how bad or mild they were on which days so I can expect it for next time. I also feel as if it would be easier when talking to an OB/GYN about my periods because my cramps can sometimes be too horrible to the point I can’t even get up and out of bed (the top reason why I’m even taking it - and how irregular my cycle was before). A couple months ago I got the subscription to Clue, and it’s even better than I imagined! I enjoy getting the articles for what I feel on my period; certain emotions, why my cramps can be killer, etc. I’d definitely recommend this app to all my fellow friends. 💕

    Clue has been a fantastic tool for me for many years now, and it's generally very good. There was a little blip when I went to to open the app and a screen popped up saying "Updating... Almost Done", but the update never seemed to finish. I contacted support and review team who helpfully replied after a few days, suggesting to uninstall and reinstall, which I was apprehensive to do, but thankfully it worked and I didn't lose all my data.

  • Amazing app!! Dec 5, 2018

    By Emz_
    Let me start by saying I have been using this app for around 4 years now and I love it! But ever since it came out with the whole “premium membership” thing I miss some aspects that I used to have. I no longer receive emails basically as a summary of my last cycle and I used to look forward to receiving those, it helped me get a better understanding of my cycle. And I don’t know if that is a feature in the premium membership I just noticed that when the app came out with premium membership I stopped receiving those emails, and personally I think that’s something everyone should have the privilege of receiving premium membership or not. But i also wish the app was a little more descriptive with its data, or at least had more options. For exercising I wish it had more options, it only has things like running and swimming but what about those who weight lift or walk? There are other things I wish it had as well like dizziness or how much you ate in a day or anxiety/depression, some of these things may already be on there some of them may not but I still think it’s good to have them/look into more options to collect data for. Overall, this app is great with tracking my period I just wish it went a little more in depth and helped you understand what all of it meant like it used to.

    At first I loved this app. It had everything I needed, but over time everything I used got placed behind the paywall subscription. I used to track my ovulation with this, and now that isn't even visible anymore without paying. All it does is track and predict my bleed time. I'd maybe buy the app, but I won't subscribe. I have to subscribe to too many things already and this just isn't a priority for it. I will have to look elsewhere to track my ovulation.

    I was okay with everything they put behind a paywall UNTIL they put the freaking ovulation tracker behind a paywall too in the latest update!!? Excuse me?? Update: I just found out they straight up removed the ovulation tracker? Which is funny because in the settings you can still toggle it on and off but it doesn't do anything so I guess they overlooked that. I really don't get this decision, it makes no sense and I will be looking for a better app. Transferring all my data is gonna be fun...

    It seems I'm one of the 'lucky' ones with the "updating... Almost done!" bug. That aside, I used to love this app, but I've been growing more and more indifferent to it, as, like many others have indicated, it has lost some features and put a lot of them behind a monthly (why?) paywall. I can't see how that business decision would pay off, as I'm going to look for another app as well, it's honestly less hassle than trying to reach out to your customer service and hope for a reply.

    As many others said. I've been using Clue for years and I hate that the fertile prediction window is gone. I do not believe that it was removed to provide better quality of information (the response Clue keeps giving people). This feature was very helpful for me and it seems many others. Unfortunately, I will be in search for another period tracker app because of this. At least give the option for people to use that feature or not. And Clue, please do not respond w/ that generic comment. Thank u

  • App struggles to load constantly FORCE CLOSES Oct 30, 2020

    By Snowzyy
    I have been a Clue user for over 3 years now and always loved it to the point that I joined as a plus member when it became available. I am happy that it is pretty much always spot on with my period predictions but for the past about 6 months it has had a lot of struggle loading. It used to be so bad to the point it wouldn’t load even after giving it multiple minutes. The issue has since gotten a bit better and some pages will load quicker while others (mainly cycle page) still take so much longer than necessary. I just feel like an app of this age and with this amount of quality in the product, should have the basics such as app programming down. I have made sure it’s not my phone or wifi, it’s the app that has problems loading. I am just pretty disappointed that my experience on the app seems to be getting worse rather than better. I hope this issue is fixed and then I’d be happy to provide 5 stars. UPDATE: Now the app is force closing itself out after about 30 seconds (and yes it is on the latest version). As you can see below, they suggested I try reporting the issue to them via the app but I can’t do that when it force closes before I can submit it.... It just keeps getting worse and it’s HIGHLY disappointing. Definite one star and am heavily considering cancelling my subscription and moving on to a new app at this point to be honest.

    I wanted this app because it would send my husband updates on my cycle, I thought I would be a fun and easy way to communicate about this. The app does do this but only in a very limited way. I can’t control which notifications he gets or edit the text of the notifications. For example, I want my husband to get a notice when my fertile window is approaching and I would love to be able to edit the alert to be something fun and sexy. No can do! He gets all or nothing, so instead his phone dings, “It’s (name) PMS today!” Then follows a long medical article about pms and a note about how my acne might be worse. I can not think of ANYTHING less fun and sexy. I feel like a medical specimen in a jar. So much for empowering women. Oh, and now they just took away the fertile window entirely with a message about how it “puts too much emphasis on your fertility.” Well... that’s why I got the app. Make it optional, something people can turn on and off, don’t just take it out and leave only an option for the ovulation day alone. You know, why not just take out the period prediction too since it can also “be inaccurate,” and it puts too much emphasis on menstruation. Why not just have the app predict that every day is the same inside our bodies? That way we can just be surprised when it’s not! Who doesn’t love a good surprise right! Oh wait, I guess we don’t even need an app at all then.

  1. The more data you add about yourself, the more accurately the algorithm can make predictions, so you know exactly what to expect every month
  2. Changed your method of birth control? Log all medication changes so you can see how they influence your cycle
  3. Rated the top free period tracker app by Obstetrics & Gynecology, a publication of the American College of Obstetricians and Gynecologists

  • Love it, but a suggestion Jan 16, 2019

    By Dr. Hajdhjshshsjjsjs
    I really love clue, it’s a really easy place to keep track of everything related to my cycle. One thing I would like to suggest is to allow us to choose if we want to log our flow (or other things) multiple times a day or just once like it is now. Personally I would love to be able to mark my flow each time I use the restroom/change my tampon/pad and have clue give me the average flow for that day. I just thought this would be a nice option since I know I sometimes have trouble deciding what I want to mark a whole days flow as (like if I’m light in the morning and night but heavy in the middle of the day). Another part of this would be to be able to log the time (if you choose), like if I get my period at 11 pm (when I normally get it in the morning). I have a really hard time remembering when I got my period and most of the time if it starts later at night it’ll go an extra day long. So it would be nice to be able to see what time I got my period, and (if marking the time for each restroom break) over time you could be able to recognize patterns of your flow throughout each day of your period. Just a couple of thoughts, but I love this app. Thanks in advance for reading my suggestions!

  • Love this app (and a suggestion) Mar 28, 2018

    By Bwilli74
    I have used Clue for years and I love it! It has helped me learn about my cycle and take control of my healthcare needs in a way I’ve never experienced. The only suggestion I have is that I wish I could track pregnancy in it as well- as far as I know there is a pregnancy option but it basically shuts down projections and eliminates the data from that time in the analysis. I don’t want to track fetal development or anything like that but it would be great if I could track my symptoms and experiences associated with pregnancy without having to mark a cycle as inactive. I had a miscarriage last fall and as we have started trying to get pregnant again I have wished that data was more available so I could see patterns and trends on months when I was pregnant compared to months that I wasn’t. As it is, when you say a cycle is inactive it won’t show you what day you were suspected to have ovulated, etc. which would be really valuable in trying to conceive. I really do appreciate this app and the work you are doing on it- I just wish it could track additional information and normalize the pregnancy experience without skewing or losing data. Thank you!

  • Amazing!! Feb 4, 2018

    By This is a Nat Attack
    I’ve tried a lot of different cycle-tracking apps and this is definitely my favorite!! However, I really wish that there was an option to indicate that you’re switching to a different brand of birth control! Also, I think it’s be nice if we had the option to arrange our days of the week according to the day of the week our pack starts on (so I start my packs on Thursday and I would like it if the weeks started on Thursdays for me). I think that would be nice, because when I went in to my gyno to switch birth control, she was interested in which week of my pack I was having the most issues and it’s really hard to tell if it’s set up like a traditional calendar. Lastly, there are a tonnnnn of options for tracking which I really love, but I know that one of the some women literally throw up for seemingly no reason at all (I, being one of them lol) and it’s be really nice to have that specifically! Because usually when this happens to me, I end up just saying I have the flu, but that’s not really accurate since there’s no fever! Anyway, I know that’s a lot, lol, but I really do love this app and and definitely think it’s the best that’s out!

    Good for being able to track what my cycles have been like before and helps me know my cycle more.i have irregular periods so it's great for me to be able to look back and see what it's been like and it gives me rough idea of when my periods will be.i don't have clue plus so idk if there are features that tell you an estimate about what symptoms to expect or what heaviness you might get and some more info on how to deal with periods and so on. In the tracker thing there aren't enough options

  • Works great Sep 8, 2019

    By Ratatattat007
    I love the way this app works. It makes predictions for you (after a cycle or two it gets more accurate) and you can customize notifications to however you want them to be displayed. For me personally, it doesn’t work as well as it would for most women because my period is irregular, so the averages don’t work accurately. However, the functions on the app work perfectly and any issues I have are almost guaranteed to be caused by my own inconsistencies. I know my period isn’t ever going to become regular because of my genes, but it’s convenient to have all of my menstrual information in one place in case I need to look back at the dates during an appointment. Love this app :) HOWEVER. Because of my irregular period, the averages show that my average cycle length is around 46 days, which is okay and all, but because that number is so high, there’s a little icon with an exclamation point on it. If I click on it, it tells me I need to buy the subscription to receive more info. It makes me really frustrated!! Clearly Clue is trying to tell me something about my menstrual health that could be helpful to my situation, but I need to pay in order to receive that insight. It doesn’t help that the icon looks really urgent and important.

    I have tried a lot of application for period tracking and this app is definitely one of the best. Good understandable interface, useful notification settings. Yes, banner with premium membership promotion is everywhere, but it is the only problem and definitely not big one. Me and my girlfriend are trying to use one account on two devices, and this application not works properly in this case. Unfortunately

    I've been using this app for years, I love the gender neutral interface. It's been great for me and I won't be going to a different app. The reason I'm writing a review is because they recently took down the fertile window feature. When I was younger it was an interesting way to learn more about my body, but now as a person trying to get pregnant, it's frustrating to have that removed. Please bring it back with an acknowledgement box that clue is not intended as birth control.

    The app was fantastic when I started to use it, but the ability to easily see symptom trends and predictions got pushed to the subscription at some point. I'd be willing to pay a one time fee for the app for some of the tools, but cannot justify a subscription service for the ones I used. I moved to Clue because it had more features than the tracker I previously had (and paid a flat fee for Pro use), but now Clue's non-sub offers a bit less (other had trends but interface wasn't as nice)

    I first downloaded Clue because I saw people talking about how it was a gender-neutral option for menstrual tracking. I like the clean and easy to use interface, the wide selection of tracking options (including the option to turn off tracking things like ovulation), and the inclusive language. What would make Clue even better for me would be a way to turn off/alter the pop-ups that say things like 'science is sexy' or, as a newsletter I just got from them was titled 'What's up with pulling out?' As someone who is a sex-repulsed asexual and has trauma related to sex, I'd like to have options to avoid sex-related topics and sex-favorable language (I'm fine with sex-positivity, just don't want it near me) without unsubscribing or turning off articles/post notifications entirely.

  • Used to be good Mar 1, 2021

    By TopHeauxmeaux
    Clue is an app that I’ve used for over 5 years. It used to be amazing. I would use it every day to track symptoms and my cycle habits and I loved being able to look forward at an estimated cycle in order to plan accordingly for packing for trips. The app gave you everything you needed to feel like you had a solid starting point to watching and monitoring your cycle, even if it wasn’t perfect. Now they’ve either removed the best things or stuffed them behind a pay wall. As a long time user that’s infuriating. You can’t see further down the months of your predicted cycle without paying money, and there is no predicted ovulation period. There’s now only one day. The entire app is based off of “this is just a prediction” and yet they removed what was essentially half the app for either avoiding or getting pregnant because of the fact “every individual is different and we can’t be sure of a window.” Then they proceed to narrow it down to ONE day of ovulation which would be more weirdly specific than a general possible window. The changes are so pointless and the opposite of helpful in any capacity. It ruins the app for me and I’ll be switching to a different cycle tracking app.

  • Too political.. Oct 22, 2020

    By S240F
    I’ve been using this app since high school, so for about 7 years. It’s been nice to see when I should expect my next period, track other symptoms, etc. however in the last year or so the app has become more and more political. Today I got an ad about abortion and being extremely pro life, I was taken aback quite a bit. I’m not here to tell other users what to do, just simply to inform other women about what this company promotes. Hopefully with this info they can make the best choice for themselves and their moral/spiritual health when deciding what tracking app to use. Personally- I’d just like an app that doesn’t bring extremely controversial topics up when I want to log my daily symptoms. Just let me put in my info and do the calculations. Anyways, I’ll be deleting my account because of this. To others that feel the same way I do about abortion, but still would like a good app to track their cycle- try out Kindara. It’s much more precise, will let you track a wider variety of symptoms, and will compile all your data into a graph for each cycle. Good luck!

  • Dealbreaker: Reminders not working Sep 26, 2020

    By Kreomedi
    Update: Reminders still didn’t work this month and will be switching to Flo after checking their reviews. This app is great. There are lots of ways to track what you want, and it really helped me figure out exactly how long my cycles average. My favorite part was the reminders because then I can pre-medicate with an NSAID to reduce prostaglandins before my period actually starts which I find very helpful for cramps. The last 5-6 months I haven’t received any reminders and have been surprised by cramps each time and then realize my period is about to start. I’ve tried toggling settings and double checked my phones notification settings to no avail. I use the free app, but I didn’t see any note saying this became a paid feature. I just updated the app, but if it still doesn’t work for my next cycle, I will be looking for another app which is sad because I’ve got over 5 years of data saved to this one. Reminders are a dealbreaker for me.

    i have been using this app since 2017 i think, and it has been very useful. lots of times, the prediction of my next period is on point. but i just noticed when i was going to track my next period this month, i suddenly can't use the app anymore. it just says "updating... almost done!" for a couple of days already.. please fix the app because this app is very important for me🥺 i will change the app review to 5 stars once the app is fixed, thankyou.
