    I’ve been using clue for over a year now and I love it, it’s always accurate and knows when I’m going to being my period! It’s like a private app for myself that I can keep personal and be truthful to myself about my body!
  • Love it

    Have been using this app for 4 years now and love it. Am able to track so many different aspects of my cycle and set reminders to make sure I log everything. The only thing I wish I could change is be able to take notes to track things that you don’t have options for
  • Best app

    I have used this app for 4 years now and love it!! The first 5-6 periods it hasn’t been completely right but after the 7th it has gotten my period correct. The more information you give the app the better it can predict your period. I highly recommend this app.

    this app is super helpful. It helps you through your cycle and even gives feedback to symptoms that you put down and tells you ways that might have caused it and things to help fix that problem. I strongly recommend this app.
  • Best period tracker

    By Thezer🌈
    This is SO helpful!!! You can track so many other things besides your period as well. I’ve found that my skin is the clearest on my period but I get the most acne sometime after my period
  • I’ve been using this app for 2 years

    I’ve been using this app for 2 years and I even pay for the premium version. This is the best period app I’ve ever used. It literally knows when my period starts down to the day and it has never been wrong for me. Down to the PMS. I do have a suggestion though. I have a heavy period and I tend to clot. Not all the time but it does happen. If that can be added as something we can track. Like how often we clot and the days you can tell you were clotting and have big clots.
