  • Amazing App!!! (And suggestion) Nov 18, 2020

    By _a_random_review
    This app is AWESOME! Periods, ovulation, pregnancy, and other things like that are SOOOO confusing (obvi) but Clue breaks things down so its easier to understand, which is really useful. And it’s NOT one of those apps that pretends that periods are the same for every person. When you enter something, it recommends articles and other things for you based on what you put in. I just want to say that this app is really useful, and well put together. It’s made by women, so it makes you feel like you’re not alone. And I have a VERY unpredictable cycle and it’s almost always spot on! And if you are taking hormonal birth control, it has options for lighter or no periods. I do have one recommendation for the app, there’s a section that asks what kind of birth control you use, right now, I don’t “have a need for birth control yet”, if you know what i mean, so I think there should be an option for that. Also they’ve started using gender neutral language in their app and even have articles on tips for gender dysphoria on your period, effects of getting testosterone, pregnancy when you’re non binary, pros and cons of daily Binding, and more. A very good, science-based, inclusive app! I would recommend for anyone with a cycle! Edit: one bug I’ve noticed recently is they have like notifications in the app for article recommendations and it’ll have the little red circle and I’ll swipe up and it’ll say ‘no new notifications’

    Best no-nonsense, non gendered period tracker app I have ever used. It serves a community that not too many people think about - not everyone who menstruates is a woman! And this app does not gender you or your cycle and gives you about a zillion options to track symptoms and triggers. This app is amazing and I will never use anything else. My cycles are irregular due to PCOS and it allows me to track more than one cycle in a single month if I have a short one!

    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.

  • 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!

  • 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.

    Always says my "Period starts tomorrow" even after it's already started??? I can't figure out how to make this actually work for me. It helps somewhat just having something to remind me to think about these things, I like that it's free upfront and the graphics/design are tasteful. Just wish it worked.

    Just updated the app. What a terrible new design. Omg! So unappealing compared to the previous one. And the notice of your next period date flashing in the middle. I don't need that. This is not the main point of the app to know your period date unless you are teenager. We are tracking symptoms, ovulation, recurring patterns etc. Probably were not consulted with women when working on new design. Shame. Plus most features become paid. And reminder to upgrade is flashing front page. Cannot remove.

    The app had several free features that are now locked behind paywalls. The developer claims that these features never existed in replies to reviews and it just rubs me the wrong way that they would blatantly lie. This was my favorite tracking app but I will be looking elsewhere to see more cycles into the future for free, get better analyses, and not have constant begging for donations.

    Used to really love this app and found it really useful and very interesting to be able to see patterns in my cycles, but the past few months I have not been able to use it properly and now since the last update it won't even open anymore. I have tried deleting and reinstalling it but it's still not working. My guess would be that it's not supported with my phones operating system anymore which is frustrating as my phone isn't really that old.

  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

    I personally love the app. I tried other apps, and they weren't as goo dad this one. No ads, and amazing content to track anything! The reason I chose 4 stars, is because I feel like I'm missing so much without the premium features. I won't be getting premium, and so so many features that are available only if you pay for premium. I respect that Clue has to make money, but not everyone can pay for premium. I would love if they added more features that were free :)

  • 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.

  • 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.

    Been using this for what it feels like forever now! I love it! Really good app, lets you track most of everything and it's pretty accurate. Only reason why I'm not giving it 5⭐ is because I wish they would add up more details to it. And other things to track too. But other than that, love it! Always recomend it!!!

  • Love the app Oct 6, 2018

    By Minnie coupe
    This app is fantastic! It allows me to stay ahead of my period, and I love that. I am never caught off guard by my period because I use it daily and pay attention to when it has predicted my next cycle. The birth control input is also very nice because i never forget to check my threads. I also like that I can track when I have sex because my doctor always asks me about the last time i had sex and i could never remember until i started using clue. The only thing I have against the app is that there is no way to add other things to track. They have a set list of things and that's all you can track. I know that there are other things I would love to track but there is no option for it. I wish you could customize your own things so that women could track things that are important to them, but not necessarily everyone. I also think it would be nice to have the option to make notes on some of the things you track, like where your cramps were or how sharp or dull they were. i know this matters to me because my iud causes me to have many different cramps. overall, i love the app and will definitely continue to use it and tell my friends about it.

  • Love This App but it Has Some Glitches Apr 2, 2020

    By meowskins23
    First, let me start off by saying I LOVE this app, and even paid for the subscription as soon as it was an option. I’m a control freak and love being able to track details like this. HOWEVER, within the last 6 months to a year, the app has been really glitchy. I kept hoping with each update that it would get better, so I held out on writing a review, but it seems that the issues have gotten worse instead of better. Each time I log something, especially something for a previous day, the app freezes and sometimes fully crashes and I have to restart. Then the updated details take a few minutes to even appear, which makes the app freeze again and sometimes crash. Also, the app crashes as every time I open it for the first time, and I have to re-open it 1 or 2 times before I can actually use it. I have tried deleting and reinstalling, which didn’t help, and I even upgraded my phone recently, but still having the same issues. Hoping these things can be fixed soon because I love the app. I’ll end this review by saying I’m not going to stop using this app because it’s amazing and very thorough, but wanted the developers to be aware of these issues. Thank you!!

    Used to be better, and free. The app is free but for who knows how long at this point. Used to give you 6 cycles in the future and now that's clue+, which costs money. Used to tell you other things about your cycle, now that's clue+. Used to have more tracking options, now that's clue+. Anyway, just annoying that all of the features are being taken away unless I pay for it. So I'm now going to use a different service.

    I've been using this app for a while and it's been super helpful for me. The one thing I wish they would bring back is being able to see heaviness of flow on the calendar. I remember this used to be a feature but now the calendar only shows a bar for the days of the period, which is less helpful because I don't get the visual for when my heavier vs lighter flow days are.

  • 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.

  • Disappointed Long-Time User Oct 4, 2020

    By DrlngD
    I NEVER write reviews, but I had to say something. I’ve been using this app now for about 5 or 6 years. I loved this app — loved all the features, all the reports — EVERYTHING. Recently with updates the quality has gone down the tubes. I’ve noticed a lot of other people sharing similar complaints, but it appears that the developers seem to either not care or are simply oblivious. Started with major issues getting the app to even load. For WEEKS. Finally yesterday I uninstalled and reinstalled — success! Seems to be working again!...Until this morning when I was essentially locked out of my account — told me I was logged into another device. Umm where? I only have 1 device! So either they have MAJOR bugs OR there’s a serious security breach. By the way, I’m also a PAYING customer — I loved the app so much that when they introduced subscriptions, I happily subscribed. Well, that’s all ending today. Deleting the app and cancelling my subscription. I’ve heard a lot of positive chatter about Flo, so I’m moving my business over there to try. So, so sad that so many of us have been loyal users only to have the developers decide we’re not worth it anymore.

  • Used to love. Disappointed. Sep 10, 2020

    By defnoshka
    I got this app few years back and made the switch from another that I’d been using. I appreciated everything about Clue - the simplicity, the educational content (that sadly doesn’t exist in many other places in this accessible format), the focus on individual patterns, and the fact that it was run by people with periods for people with periods. I think certain functionality can be more sophisticated, but I made the switch anyway. The recent changes to the app (to make it more financially sustainable, apparently) are absolutely abominable. The most basic tracking and educational content have a cost now? Is this what you stand for? In this economy, and in a world where even tampons have a tax- we also have to pay a fee (and not a cheap one) to just document our period and understand our bodies a little better? You’re using our data to drive your research, but you won’t even let us see the most basic predictions? I know it’s financially supporting you - but how is this supporting your mission? How about another solution, like adding more ads by responsible brands? I refuse to get Clue Plus and am looking to switch. Do better, Clue.

  • Constantly Loading - Update Jun 30, 2020

    By CharBear__
    I’ve been using Clue for years and it was my favorite Period Tracker app but for the past several months the app has not been functioning at all. The calendar doesn’t load and neither does the Cycle feature. I hope that the app is fixed soon or else I’ll have to find a new favorite app. Edit: I now see that they’ve changed the app and require a purchase in order to use the most basic functions of the app. Whenever I go to my doctor they always ask “When was the last day of your most recent cycle?” and now with this update I can no longer answer that question unless I decide to pay $5/month which I absolutely refuse. I will be deleting this app and downloading one of the many other FREE period tracker apps. Responding to the developers response: it would’ve been nice to receive a notice before hand that the app would be changing and most of the basic functions would not be available anymore without a purchase. I would’ve been more inclined to support but this was underhanded and forced on your customers who have been loyal for years.
