Ratings and reviews

The app is great when you first start using it. The tracking features are better than those on other period apps. The biggest issue is that after a while of using it (in my case after around 9-10 months) the app gets terribly glitchy and it can't even be used properly and a lot of the time, it predicts my period coming at insanely far off dates. TLDR; the app gets very glitchy and inaccurate after a while.

So incredibly glitchy and laggy. there have been so many times I've opened this app to quickly check something, or give some information to a doctor, and this app just gives me a blank screen when trying to open it. It's annoying and embarrassing. not to mention the whole issue going around about stardust selling your personal data. It's a shame there aren't any good period apps out there, all of them either suck or sell your information.

Clunky UI makes it hard to understand and edit information. Any time I try to go to a specific date to edit flow, it asks me when did my period start. But my goal was to record what my flow was on another day, not the first day. The animations are unnecessary and frustrating. One pro is that I'm not constantly getting pop-up ads. But I find the UI is a worse issue when it comes to how easy it is to use. I'll keep it around for 1 more month to see if it updates, but if not, then I'm deleting it.
