This is my preferred app. I had some issues at first. I had downloaded and input all my previous months cycles accurately, and in the settings changed my cycle and period length. Not sure why but I had trouble getting it to save. I had to redo that 3 times, and still noticed my prediction and cycle length would revert back to standard. I think it's been fixed though, the last time I set it seemed to take.

I like many features of this app, but period tracking leaves much to be desired. it is incapable of back dating period start dates (ex. if I input my start date on my second day, it still sets "day 1" for a later date, which makes it impossible to provide accuracy) which is frustrating when i am trying to use this app to calculate my phases. Might delete just because it is so inconsistent.

I just downloaded this app, coming from clue, but the app is so laggy and buggy it's unusable. I was able to track symptoms on 2 different days before the app stopped saving the symptoms I enter. It's also extremely slow and laggy, takes forever to refresh, and sometimes the whole thing will freeze, it'll be totally unresponsive, links won't work, etc. It's...really bad. Like. Really really bad.
