App Reviews

  • Could use this, would be helpful

    By Ababobaloo
    I love this app, it’s super accurate to when my period comes, but I think it’s lacking one thing. I think it would be nice if in the calendar section where you can see when your period is predicted to come, it also had the option to add in an event. That way, you could see when your period is and know if it’s going to interfere with your period.
  • best period tracker ever!

    By Bria661
    it’s always accurate from when i’m about to start my period! also convenient for doctors appointments because if i get asked when my last period was, i can go back on the app to see when i had my last period.
  • Love this app

    By savanahh.1
    This app is pretty accurate. It tells me around the time I should start and its correct. I like the questions it asks me. Good app overall!

  • I love this app

    By Hellethil
    It’s pretty accurate. Could you guys make it more accessible to blind people please? It’s a really good app and accurate, it would be nice if it was more accessible for those who can’t see when they’ve started their period.
  • *UPDATED* Less than stellar app if you aren’t a woman keeping track.

    By Kegmeister
    *Update* All the versions later and none of this stuff had been addressed. I even did the beta testing program through test flight and submitted the suggestion repeatedly via support. What a shame. Now Apple is building this directly into the watch and health app. Since Clue doesn’t want to update this feature that will be the key differentiator between them and Apple, I guess it’s time to admit defeat and prepare to go all in with Apple health/watch app and leave clue behind. Also, the only major change is that my wife no longer “loves” the app. She pretty much already said “what’s the point then if the sharing features don’t work?” and pretty much just logs directly in the health app. She lets health update Clue so that on the off chance that a notification does work, I might get a notice. *End Update* When my wife discovered this app one of the biggest draws for her was that I could download the app, create an account, and she could share her information with me so that we could both be well informed of her menstrual cycle so that we could utilize this information together. From family planning, support for her, shared information without the awkward conversations it was supposed to be great. But I have to tell you that if you aren’t using the app to track your own cycle then it is garbage. Make no mistake, my wife loves the app. I hate it. If you are just following and aren’t tracking you can’t even have access to the app settings. The app on the Apple Watch is useless because it will only keep track of “my data” which there is none and there is no option to have my wife’s data show up. The only perk is that the notifications sometimes work on my end (always for her on her end). Why can’t there be a dedicated set up for a supportive spouse/partner who is following? My wife should be able to customize just how much I can see based on her comfort level (if she doesn’t want me to see her additional data like flow or emotional health, she should have granular control over that), then I should be able to then restrict that further based on what I find useful, and at the very least I should be able to set her cycle for my Apple Watch display and be able to access the very basic app settings such as “Apps and devices,” “passcode” (why can’t I also be able to protect my wife’s data from my phone, why does she have to sacrifice her privacy because I can’t access a setting on my device?), “language and units,” “terms of service,” etc. Wife loves it. She gives it 5 stars. I hate it. I give it 1 star. Because zero isn’t an option.
  • 🎉It’s Exactly What I Needed🎉

    By My Ballooooon
    This app is amazing! It’s almost always accurate (because, you know, you’re body’s not a clock, it’s not going to be an EXACT month apart every time) and the more you use it, the more it’s specialized for you personally. It also tells you if it notices a pattern during different parts of your cycle. For example, if you’re tired during the first few days each time and have a craving for chocolate 🍫. You can also set it to remind you when you’re about to start your next cycle, which honestly has been a life saver 😅. It also give you a lot of information and advice about your period AND your fertile window, I couldn’t think of a more helpful app which also thinks about my health. AND ITS FREEEEE! 💸
  • Knows me better than I know myself apparently..

    By RM4139
    I never write reviews but I absolutely love this app. This thing tracks my period better than I can. I got a Notification that my period was coming tomorrow, and sure enough like clockwork it was there. I also like being able to log and track my pms symptoms. When I start to feel certain moods, I know it’s literally just my hormones for that week. This app is truly amazing.
  • Great app but...tiny suggestion

    By Andry0510
    I love this app. It’s amazing. Here comes the but... I share my cycle with my husband and he can’t experience the app the same way that I do. I would enjoy this app more if the person I’m sharing my cycle with (in this case my husband) can experience the app the same way that I do. I want to share with him so he can see if I am upset, in pain, craving anything, etc. That is the best thing about this app. It lets you track everything. Thanks!!
