User Reviews
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.
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.
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 like it a lot, especially the ability to have your partner check your cycle as well, but I do think the definitions of certain things shouldn't be something to unlock with a subscription. It would make sense for actual extra stuff, like the "Your daily decode" deep dive stuff, to have a subscription, but when it doesn't let me know what the definitions are of certain symptoms according to the creators of the app, it irks me a bit.
