I've used this app for the last few years, and it's absolutely amazing. I don't pay for the ad removal, yet it's still a great app with what feels to be the minimal ads possible compared to other period tracking apps I've seen and tried. I love being able to track mood swings, period aches, weight and more, and the reports are really good too. Stress makes my periods much worse, and being able to track when it's worse than normal does help a lot when my mind is already so jumbled lol

I've been using this app for a little over a year now and it's fine. I enjoy all the options of what I can record to see a pattern with my symptoms. With that being said if you have slight irregular cycles, and I mean like a day or two early or late between months. This app will not be able to track or accurately predict your next period. I noticed this a few months ago and now its a week off. The app doesn't correct itself even though you input your information, it just says you're late.

Hi! Did you turn on "Use Average" for smart prediction(More - Cycle Length)? It is predicted based on your recorded data. The more records, the more accurate the prediction. If the issue remains, please send us more details via "More -> Bug report&Feedback" to help locate and optimize it. Thanks!

This used to be the best app. Now, I can hardly ever get into it. I understand the necessity of adding ads to the app. I do. But now when I open the app, I sit through the entire ad, wait for several more minutes, and still don't get the option to continue to the app to track my dang cycle 90% of the time. It's ridiculous. I have years of history in this app that I can't access most of the time.

Hi, sorry for the unpleasant experience and thanks for your years of support. We understand long, unclosable ads can seriously affect usage, which is not what we want. If possible, please send a screen recording (and the ad link) to periodtrackerfeedback@gmail.com. We will investigate and improve it as soon as possible.
