Love this app

I used to forget when I had my last period. So I never knew when my period was coming. I wanted an app that could track my periods and predict when I would get my next period. I have actually had this app for several years. Because I use it religiously, it accurately predicts my next period every month. I highly recommend this app.

Easy and effective

Easy to use and navigate. Can be as simple or robust as you’d like the app to be. Has been very helpful for me to know when my period is coming since I’m not on the pill.

I got this app since my old one was no longer being supported, worked well enough to track cycles and keep track. Notifications never came through until I went on to the app then I got like 4 pop ups at a time for ones it missed. Gonna try something else to see if it works better.
