  • 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!

  • 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.

    I like this app a lot, as it helps me to keep track of my period symptoms and manage them. However, a few days ago now, I can access the app, I just can't really do much else; every time I try to track something the screen goes black and freezes. There was an update in-between this issue that resolved it, and now, a few days later, I'm back to the same problem. This app is my go-to when it comes to my period, I just can't seem to use it now. If you could look into this, I would be grateful.

    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!

  • 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'm so disappointed by the new update. This app was perfect and I recommended it to all my friends for years. The new UI is counter intuitive when the previous design was seamless (I actually used it as an example for great design in a UX class) but now I'm going to find a different app. It's so obvious that the free account experience has been "downgraded" in an attempt to convince people to pay for a premium account.

    I've had Clue for years and I've loved it. The problem now is that in order to do anything really, you need Clue Plus. I understand that they need to make money, but it's really gone downhill. The features are harder to use than they were in the past, and now I'm getting ads too. At this point, I'm considering getting another app to track my periods. Things are more confusing and the screen is cluttered when looking at all of my cycles to compare which I can't really do anymore either.

    More than upgrades would be best called downgrades. I have been using this app on and off for years now. At the beginning was one of the best tracking apps out there, now a days you need to pay for Clue Plus to access most functions, even those that were available for free before. Interface keeps changing to be less appealing and more difficult to navigate. With no option to personalise it to your liking.

    Used to be such a helpful app. Then they updated and now you have to pay a subscription to access information about your period that used to be readily available. The information that they do give you access to for free, is limited and unhelpful. So disappointing that all these changes, have made the app virtually useless. I am looking for another app or watch and I will uninstall this because it's literally wasting space on my phone.

    I have used Clue for years, mainly to track when my period is due and symptoms. It was excellent before the last update. Now it is lagging so badly I can't even log my symptoms and it is pretty much unusable. I am very disappointed as I used to recommend this to family and friends and enjoyed using it before now. Something drastically needs to change because I can see in other recent reviews people are losing faith and loyalty with Clue. 5/5 before now and holding hope the issues will be fixed.

  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

  • Trans-friendly!! Dysphoria Tracker? Feb 6, 2019

    By daniel213134212
    This app is AMAZING, especially for transgender folks with periods. I am trans, and not a woman, but I get a period. I really appreciate the fact that the app doesn’t use gendered language. This makes tracking my period much less uncomfortable for me. It also has a pretty great color scheme. One of the main reasons I track my period is because I get more dysphoric on my period. Gender dysphoria is something many transgender experience. It can fluctuate based on many factors, including hormones and menstrual cycles. Because of this, it would be SO WONDERFUL to be able to track gender dysphoria on the app. It would honestly be groundbreaking. I already love the app, but I would love it even more, and I know a lot of other people would too. Trans people may not be your main demographic, but we likely still make up a fairly significant proportion of your users. A dysphoria tracker would help many of us immensely. It would also likely draw more users to the app because no other app offers that. Thank you so much for all you are doing for transgender folks with periods, and I hope you will consider adding a gender dysphoria tracker! Love and Light, Daniel

  • 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!

  • Amazing! Jan 27, 2018

    By michaelam15
    I suffer from Polycystic Ovary Syndrome and have a number of symptoms throughout my cycle which can seem random, but Clue helps me understand patterns and recognize anything out of the ordinary that I may need to discuss with my doctor. I also suffer from anxiety, and the tracker for emotions and motivations is so helpful. When I have a bad day and feel like my whole life is going badly I can look at the calendar and see how many days I've marked as "happy" days. The other types of tracking are important to me for other reasons too. My mom died of ovarian cancer a year ago at a young age (early 40s) and I've since become worried about my health. My doctor told me that I should track my symptoms (i.e. any irregular pains) so I can have a peace of mind knowing that these problems are part of my regular cycle or something that needs to be checked. The only thing I would suggest to the developers would be to incorporate a section to track regular, daily prescription medications. I currently use another app for this but if Clue could find out a way to add it on then it would just be unnecessary. Either way I love the app and it constantly is getting better.

  • Easy to use Sep 30, 2019

    By Kellomatic
    I love the simplicity of this app compared to other I use. I love that I could share my cycle with my partner should I choose and that all my information is available in one spot so I can easily relay it to my doctor. I came here to write a review stating that I wish you could add if your cycles are irregular or if you’ve been diagnosed with PCOS or other infertility issues when I saw there was a recent update that mentioned PCOS. After updating and looking through all the settings and options I had to go back to the update features to learn that it will only prompt you to take a survey once they’ve deemed your cycles are irregular. It would be nice if you could just input that you are irregular or suffer from infertility issues that have already been diagnosed without having to wait for a cycle to complete. Because with PCOS we could be waiting anywhere from the automatic 29 days clue starts you at to 90+ days which means you don’t get insights because you haven’t actually completely a cycle yet. If you were able to put on your diagnosis or irregularity then clue could give you insight into what your last 30 days has looked like instead of *one* cycle that could be months of waiting

  • 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.

    Not a fan of display changes The tracking display seems to have changed - the days on the calendar no longer show different amounts of red making it difficult to distinguish a heavy day from a light day. Is this something I can change? Also the period indicator on the overview page just shows the period lasting a set amount of days instead of as long as it actually is. I don't like the display changes, it makes it very difficult to read without looking at each individual day's data.

    I have used Clue for years and love it! But the recent changes to the visuals really throw me off. The fertility window and period colors are very similar and now that the visual indicator for the fertility window was the previous indicator for period strength on different days, it's confusing and not helpful. I miss taking a quick glance and seeing "the second day was heavier that month" rather than the straight line. It takes down the usefulness more than expected. Wonderful app otherwise!

  • 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!!

    Clue is another great free app that became less great when the subscription model hit. I used to use it every day and it gave little insight because its algorithm is based strictly off of bleeding, not pattern recognition. I dont always bleed, but I do have cycles.When i emailed support, they told me to put a fake period day each month for tracking purposes, which defeats the purpose. It is the absolute best in category, and if you have a period this feminist app will probably be good for you.

Skip forward a little more, now I'm getting ads, the interface is broken, the colors have changed to be too similar (pink and red when the teal and red were just fine? Why change?). Honestly, I'm goving it a little more time, but I think I'm uninstalling and finding a new one.

  • 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.

  • Updates force you to use the paid version Aug 7, 2020

    By KLP@
    I get it, everyone wants to figure out how to make money... I have been using this app for YEARS. I use it to track everything from exercise, to cravings, to sleep, to headaches, pretty much everything. Until recently, I was able to access (my data) freely to see any patterns or notice any abnormalities. Now, to review this same information that I’ve been inputting and accessing freely FOR YEARS, it’s locked and requires a paid subscription. I probably wouldn’t be upset if the paid feature was to access new information or newly added features but to take my information that was once free to access (which by the way is shared with researchers according to their terms of use) and charge to review is ridiculous. If this is information that will be part of the paid subscription, take away the options to add this if it’s not accessible in the free version. It makes no sense that I’ve freely accessed this info for YEARS and until recently could track my own data without problems.
