Reviews From google play store

This app has been an absolute godsend for tracking the various issues I've been having with my periods over the last 3 years. Thanks to being able to track what's going on, I am going through investigation for endometriosis. But new illness = new costs. And I can't justify spending over $100nzd a year for an app that previously only cost $16.99/y. I'm appalled at this price jump. I've given my data, and I feel abandoned now. I will have to find something else.

I am using this app consistently since 2016 (without paying)! It's practical and straight forward. I use it only for tracking of the period and predictions, which are great, but it also allows to optionally track other behavior or emotions at any day, not only restricted necessarily to the period days. What I found interesting is the Encyclopedia with reference to research. Overall, I can highly recommend this app!

I've been using the basic, free version for quite a while now. It has given me huge insight into how my cycle impacts my life. I love the customization options for what to track. There are some new ones in the past year that have really helped me understand how my birth control choices, hormones, and now age are influencing my body. This is a great tool if you are tracking your fertility or characteristics of your period. The information is useful both for you and health care providers.

I like using clue. I find the app easy to use and helpful with keeping track of my cycle. I also create other little tags when I am feeling unwell to see if there is a pattern. It's super helpful. The app also gives me a heads up to when I am pmsing and I really appreciate that. I don't really need to track my ovulation but it does tell you that.

So, I've had this app since June and have had enough time to play around with it. It has been super helpful in tracking my period and ovulations, and it does give me notifications for events (only what i select). After about 3 months, it's gotten better at predicting when my peiod ahould appear. However, my periods vary a lot so it does average number of days for your cycles. I wish it had more options in the exercise category or they were more general. Overall, i think it's been pretty helpful.

This is a great app to track cycles and Monitor your general health or fertility. I appreciate that if anyone was looking at my phone they would not see the icon and know that that was my cycle tracker. I like that you can track other symptoms along with cycle flow, and I also like how it can predict cycles, and that you can choose to have the algorithm ignore cycles if it was not a natural cycle- for instance if you were working with a fertility doctor. Love this app.

This app is very useful and easy to use. Additionally, as it is used more it is actually able to accurately predict periods which is wonderful. The amount of things you can record each day is great; however, I am confused as to why it does not have an option to record implant birth control, that seems like something that'd be important to have as it definitely affects the period.

I LOVE this app!! I have recommended this app to so many friends. As a constant traveler, this app helps me track my cycle so that I'm never caught off guard while on the road. I also used this app last year when my husband and I decided to expand our family and we we able to conceive the first month partially due to the accuracy of this app! I can't say enough great things about Clue! It has been truly empowering to come to know and understand my body the way I have because of this app.

This is the first menstrual tracking app I've been able to stick with, thanks to the straight-forward minimalistic design, and customizable alerts. It's not going to wow you (to be fair tho, how would a period tracker wow anyone?) but it will absolutely work properly 100% of the time, and not inundate you with unwanted/useless notifications or ads.

One of the most helpful apps I could ever get. It successfully tracks my period and warns me to not forget my pill, which is really needed at times when I get too engrossed and forget other duties. Plus, the podcasts where they discuss different aspects of our hormones and what they do to our bodies. Definitely recommend to all ladies out there!

I have tried a few period tracking apps, this was the one I always went to so deleted the others. Can't see how to get a temperature graph which would be really handy but you don't really need it because the app does its own calculations and becomes eerily accurate in predicting period (hence presumably other events too) ... even when I'm very slack about inputting any data.

This app has been wonderful at keeping me in touch with my cycles and the trends that are occurring such as flow, moods and cravings, etc. It reminds me when I'm late or forget to input my info and has medical information that lets me know if something should be mentioned to my doctor. Great app. I'm starting the beginnings of menopause and this app has been very helpful with tracking my symptoms.

Reminders (notfiications) don't work despite being enabled in in app and phone. The calendar view has always seemed clustered to me. The app is still not programmed to use cervical fluid data entries (part of Fertility Awareness Method) for its calculations. Edit: Now constantly markets extra features before I can access the actual app. I have to tap 'back' to avoid the annoying reminder.

The more info you can enter the better this app works! It is pretty spot on about telling me where in my cycle I'm at. And you can review past symptoms to see what's "normal" for you. You can also enter emotions, cravings, and so much more. I switched to this app after my friend used it and I haven't gone back. Even when my cycle was out of whack, it still calculated when I was going to be back on track. Definitely recommend!

This one has no pregnancy / breastfeeding options despite having said it is under development years ago. And it is quite confusing with its IUD tracking. When adding IUD, the way of tracking should change completely until it is removed. Instead I get a dot on the calendar for that one single day. So what should I do the next day? Once again add IUD? And so on for every single day for years?! Finally, I still can't set the calendar to start the week on Monday, despite changing several devices

I absolutely adore this app, been using it for years, but now that it's suddenly decided to need a paying subscription (£4 a month, which I find outrageously expensive, especially considering I'm a student) and has blocked me from accessing my data until I buy a subscription, I'm incredibly disappointed, I don't want to have to spend that much money on period tracking when periods are already so expensive, and will have to start tracking on another app.

I pay the anual fee for Clue because I believe their research is important and useful for all women. I try to keep track of everything everyday and I really respect that they don't sell user data for profit. The app is so great and handy! My only complaint is that reminders aren't really as useful as I expected them to be.

Is easy to use and easy to follow your cycle. Which is great for anybody who wants a simple visual to keep track of their cycles. The app also includes optional choices of how your mood, sex drive, cravings, and etc can predict your next period and gives information about each opt. choice. 👌

Boyfriend here! just want to say since I don't see many guys in these reviews that this app is really useful for us too, provided your beloved is willing to share it. My gf invited me to track her cycle so now I can know where she's at just as easily. It's really helpful in knowing when she's fertile, since for her most forms of birth control aren't an option and we like to avoid condoms. Knowing when her period starts is useful too, gives me a heads-up on when she needs that extra bit of love🥰

it's really good and almost always accurate, if it's off it's only by a few days. and the symptom tracker is really helpful. I've had this app for years and I use it all the time not just for period tacking app for tracking everything else what's the app

The app is great it gives me real dates when I am going to get my period. It was off a little bit by a few days the first time I got the app and now it's way better. It takes a like three periods to get the actual date but not it is the date the I always get my period

Well designed. I love that it has a clean, simple layout that isn't covered in flowers. Very non-binary friendly. Covers loads of issues. Has helped me keep track of some of my side effects for new medication have I adjust to it.

I love the versatility and accuracy of this app. I have used it for years and appreciate the changes that have been made until today. I ran the update and the fertility window and predictions were gone, historically, for the current period and for the future. Why??

The best period tracker out there. It has scientific backup for all information with the appropriate bibliographic references , the analitics based on your information is very accurate and the graphic design is really dapper and very user friendly. I LOVE IT!!!

I use this in the most simple form, tracking just the bleeding. Yet it is surprisingly accurate with the predictions of when my period will come, even a couple of months ahead (and will quickly update predictions those rare times I'm early or late!)

This app has given me so much insight on what's going on in my body, it also reminds me to take my pill, gives me a heads up when I'm about to start my period, as well as what symptoms to look out for. 100% changed my life. I've recommended it to every woman I know.

Really helps! I get really emotional during pms, but only like 2 or 3 times a year. This helps me know I'm not going crazy. It's also helpful in knowing when a condom is needed. Honestly like this enough to pay for premium.

We got pregnant after 6 cycles using clue. Only thing I'd change is when you put a positive pregnancy test in the tracker doesn't change to reflect kind of just keeps waiting for your period to start. Great app though!!!!

Always comes when it says to come it doesn't need WiFi and it tells you a monthe before your next one. As a teen it is used every day and its so helpful. You can say good bye to having to write it down all the time.

This app is the best thing I have ever done for myself. Can't believe that before clue I had no clue about the power of tracking my own cycle. This is now my primary birth control method. Been using clue for three years.

This app is amazing. I can track what I need to and learn more about what's going on in my body. I really like that it also provides ways to ease the pain of menstruation. The notifications are nice because you can customize it to suit your lifestyle.

The only reason why I didn't rate it 5 is because it doesn't have an exercise category for strength training, only Yoga, biking, swimming and running. Weight lifting doesn't fall in any of those, and it's important for me to track it, please add it. Apart from that, it's a reliable and very informative app.

So helpful! The more information about your menstruak cycle you put, the more accurate and perzonalized the results are. From birth control methods to your hormones and they effect they have on you. This app is pretty helpful for us women.

This app is really useful and helps stop my periods from being a nasty suprise and helps me be prepared, it's good to be able to keep track of your cycle so you can see if it may be irregular and I feel more organized having it all written out 😊

It is very accurate and super easy to use. I haven't really used it in like a year and it saved all of my old information. When I came back to it, it still predicted the exact day that I would start and it was accurate.

The best period tracker I've ever used! Not pink and girly, never uses gendered terms, and tracks WAY more things than your average period app. Very customizable, ypu can hide the trackers you don't want to use or see. Great for trans people with menstration <3

No offense, but I just installed this and just from the start I see this ain't working. It won't let me put my period length, it put four days itself like it already knows. As for the other stuff I didn't even bother to look at them.

Really like the app. I use two different ones to see if another would be better. In the end though, I find that clue tracks my cycle very well and is almost always accurate.

My period is never on time and I've had mine for all ready about 5 years. I could never figure out what day mine would be on so I started looking for apps and using them but none of them would be accurate for my period cycle until know.

It's crazy accurate, and has a bunch of things to help you get your cycle on track. It also has great information for those looking to understand more about what's going on with their body. Very helpful.

I saw some YouTuber recommending to try this app and I decided to give it a try and it's the best app for any women to keep a track of their cycle! I've been using this app from 7 months now! Thank you! 😊

Great for tracking my periods. I now realize how irregular my periods were and how much energy my period takes out of me. It will definitely help you at your next gyno appointment if you can't remember stuff like me

It's very hard to track very irregular periods with clue, I wish there were more options for bodily fluids and other symptoms. Other than that, the app is amazing.

I believe it would be nice, but I don't believe we should have to give out our payment information just to keep up with our period. I can do that with pen, paper, and a doctor's visit. No app needed, no offense.

Great and informative period tracker. I have only used it for a month so I am not sure about the predictability. It would be great if there is an option to customize a tag that is not on the list.

I really enjoy this app. Its extremely easy to use. I like that I can record my moods, skin, weight, its great. The period reminder is nice as well. Great app!

I'd give this app 4.5 stars. It is very helpful and relatively straightforward. I feel like a few simple additions would make this app perfect. I will continue to use this.

It's been really useful for tracking my SPM and my depression swings, and I've realized a lot of information about the changes of my body. You need to be cosntant, though.

I love it it makes tracking my period so much easier and it even tracks when id ovulate an it showes you 3 months of predicted period times based off your first tracked period. I love this app and dont think I'll ever change it's so easy and simple

It was free. Now gone to a monthly subscription, which frankly you put all the info in and it guesses a date of your next period. 3.99 a month for that? Get a grip. Will be uninstalling

I've been using clue for a few years, and it's absolutely the best period tracker I've used. Price is great, variety of symptoms to track, plus super customisable. Really impressed!

Great app, simple and easy to use. I particularly like how that they dont sell your data unlike other similar companies. Can you please add a chart view to visualise temperature.

Great app. Simple to use. I've been using this for years. If you want access to more features you have to pay a subscription fee, but the basic level does exactly what I need!

Used this app for years. Its very easy to use. And the data is used for medical research and education and no marketing. Also I personally love that there's no pink in this app.

Great way to track your period and it's pretty accurate! I don't like being on the pill bc of all the side effects so I track my period this way.

After using this app for years, I finally got around to creating an account and backing up my data a few weeks ago. I just checked today, and ALL OF MY DATA IS GONE!

Its a very helpful app, (when I don't ignore yhe notifications to put in my info). Very constomizable and it's an easy way to keep track of the blood waterfall that we are cursed with lads.

It is a great, my only challenge atm is that when I enter data is doesn't recognise I have ovulated, but I want to see how close it will get after a few months of tracking

It is the best tracking app I tried. Everything is user-friendly, pretty design and the most important — tracking algorithms work very good.

I've found this app to be extremely useful for tracking my period. I also find it a useful tool to look back at my previous cycles to see if I can tell any trends/patterns to help prepare me for the next one. The information/resources provided within the app for the "whys" and remedies I find invaluable. They also have sources for their information which I find reputable in this day and age. Lovely app, and easy to use.

Everything I could ever want. Keeps my data for me to see, accurately predicts my next period. Easy to use. A cute look too!

This is the best app I could find. It's highly convenient and user friendly. You can also view it offline and get regular notifications too if needed.

Simple and straight forward. Gives you a heads up when your next period is coming. Can track other stories if you want. Not pink and froufrou which is nice.

Such a fantastic app for tracking. I love all the customizable options and I love that it isn't overly pink or heteronormative! Thank you Clue for making my life so much easier 😁

I wish the subscription was less pricey and also incuded entering plan b easily with out subing, but its very nice to use with out as long as you keep up.easy to use ive had it forever and you should too tell me if u see a better app worth 5 stars tho

I've been using clue for 5, almost 6 years now. I've never used another period tracking app. The accuracy is hit or miss, but I think that depends on the person. It's usually a couple of days off for my personal flow. It has so many option for tracking, and even has reminders for birth control. It has a lock function so it's safe from prying eyes, and allows you to transfer information onto a new device. I love this app, and I'd recommend it to anyone who needs to track their periods.

Really helpful and even if I do a bad job of putting in information I still can look at how long it's been since my last period and assume that it's coming up.

It's a life saver ! I could never keep track of my cycle until I got this app. It's great at predicting your next cycle and if you add in how you feel , cravings , exercise.. etc. that plays a big role in the next prediction . They have so many helpful facts to help you understand things about your body .. Great for any age ! I recommend ❤

I love this app so much! Even though my cycle is slightly irregular, this helps me get a general idea so I'm prepared.

This straightforward app helps me track my cycle and write notes. I love the cycle analysis overview that quickly shows me (and my doctor) what my cycles look like.

This app is reliable, easy to use, and I love that it includes all kinds of info about periods and symptoms. It's super useful!

I like this app and it's been few years I used that . They're always online and available for support you data missing or some questions. Thank you Clue team :*

I've been using this app for a year now and I can say that it really helped me so much. Sometimes the prediction are not right, but its okay and still awesome.

This is great! Not only is it helpful to track your cycle, but it's also extremely informative as well. It's honestly the best!

Love this app! Helps me stay on top of my cycle so it's never a surprise. Use this consistently and it works.

Loved this app, as it was for free, now after update you have to pay, so will uninstall it, as there are lot of similar apps for free.

Brilliant app, has lots of trackable options beyond period bleeding. And anything not covered can be tracked easily in the notes. Indispensable.

It's a great app! It works amazingly and keeps track of everything that i need to know. It's informing and i've learned a lot about myself

Great app... easy to use, tons of information to document and keep track of!!! Love it.

Clue is a great tool for tracking your period and related symptoms (when exactly do I get PMS? When do I get cramps and break out? How do these relate to when I'm going to get my period?- I now know how my body works and can recognize what my body is telling me bc I'm able to see the patterns and predictions in Clue.)

Super easy to use. Useful reminders for when my cycle is expected to start based on previous data. Shows ovulation and pms windows too.

So easy to use, and I love the updates & notifications it gives, in case I forget to track. Thank you!

I have been using this app for more than 3 years now, and I must say, this is one of the best apps I've ever used. I try to track every day possible and it has been very accurate with the predictions for me. It's an amazing app to track your physical and mental health throughout and month, and to know your own body cycles better. I absolutely love it and I recommend this to every woman.

I have used this app for 4 years and it has been so helpful! I woke up this morning to find all the information about previous ovulation periods wiped from the app and now I need to pay £5 a month to retrieve it - I am so upset that this has happened and now I'm moving onto a different app. It's not so much having to pay that's upset me, it's the lack of warning from Clue. Quite sneaky in my opinion. Oh well, it was good while it lasted. Plenty of other apps that I can rely on to track my cycle

Loved this app and have been tracking my cycles and ovulation windows for almost a year now, but now the latest update is bulky, non-user friendly interface, and can no longer easily see the unprotected sex days during ovulation window in the summary screen. Not to mention having to scroll past a million options to get to the past cycle summaries. This used to be a helpful tool to show my infertility doctor. Please change it back!

I will admit I am not religiously calendaring my cycle but today, I realized that I have been using this app for more than three years already, which means at I least have enough brain cells to remember to at least update the most basic stuff. So thank you very much Clue Team because I think without the app, I may have been not tracking my cycle at the very least.

Best app for any and all women to have. Not only can you get a more accurate prediction to your period but over time, it gets more reliable and can predict up to 3 months, which is great for planning trips. I'm definitely more aware of my body and being able to show your doctor your calendar is useful. I tend to forget anything not written down so this app is an amazing tool. There's a lot to learn and articles to read as well. Best subscription service I have.

Such a great app for helping with tracking my periods. I always thought I had really awful periods that weren't regular but actually I've found I'm not terrible and I'm actually pretty normal! 😂 It's great for tracking thoughts, feelings, weight and many other things. No doubt when trying for a baby it will come in helpful too!

What a beautifully made and simply an amazing app! I have been tracking my gf's period for over 4 years now and it's really amazing how nicely made this app is, the information and the ability to add multiple emotions (Happy, sad, etc) is really funny and cute too. Great job on your team is one of fav apps :) i even recommend it to my other female friends!

I knew that eventually the app would cost money, however I've been using this app for years now and would have loved it if there was some type of bonus for those of us who have used the app for a long time and have told a ton of people about it and gotten them to use it personally. It's a bummer that all the details and information that I was relying on for knowledge regarding my cycle and physical responses are now gone and all I know about is when I'm supposed to get PMS and cycle. Not cool!

It used to be a great tracker. But since a few days many of its features have been missing. Is feels like something useless now. And I am so not happy with this new updated version of the app which looks like a downgrade rather than an update. I would have given it a 5 star but I would rather give it one now. If the developer reads this then I would like to request you to bring back the better version it used to be before which was sth great and so helpful.

Great app. Subscription is not worth it. I really like this app and the tracking options that help to identify patterns. That's why i decided to get a yearly Plus subscription which i found really disappointing. The benifit is that it should send you extra info and advice and for the whole year it only showed me two pieces of info about cramps and acne which alreqdy exist somewhere else. I didn't get any personalised information so i cancelled and switched back to the free version.

I've been using this app for a few years now, and I love it. The one time I had a problem - and the problem turned out to be my equipment, not the app - I found their support staff to be incredibly helpful. Also, according to my research, Clue is one of the only tracker apps that doesn't sell our information. That's a big deal for me.

This is the first time I've tried tracking my period, it's been very accurate so far. I love how you can customize what you want to track (cravings, exercise, cramps, hours of sleep, etc.). If I haven't tracked anything for a few days it gives me a reminder. Highly recommend the app!

I love this app. I wish I could tweak it to be more specific to my situation. i.e. cramps, I get them in my back, not my stomach, so if there was a problem for them to warn me about, it would be missed... there's a lot of that kind of thing. I'm sure that's something that might happen later on, but for now it helps me keep track of not only my cycle, but my moods, diet, exercise, and lots of things.

This new update is missing some things like in the cycle history I can't see everything like I used to like some categories are missing all together and some have only one thing from a category. Can I get an email to talk about this I love the app even pay the monthly thing for the plus, but this new update should show the same things as it used to.

I use it for tracking of periods and symptoms related to my endo/pcos that I feel daily. Also PMS. I have the free version. I like it a lot. Easy to use. Clear. Concise. Detailed. You can add your own things as well. It was right on point with my cycle. It learns the more you put in and track.

Been using it for years and I love it. Very accurate and has a great variety of option to use for tracking your cycle

Amazing period tracker! Made by and for women. Has a lot on info and they also do the most interesting podcast! TOTALLY recommend it!

Great app! Love the functionality and design. Makes it so easy to keep track.
