Ratings and reviews

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 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.

It has so much potential but can be really buggy. I have had to uninstall and reinstall a few times just to get normal use from it. There are still annoying issues like the same message popping up throughout the entire cycle in one month but then different messages (like it's supposed to) coming up daily in a different month. Pages take forever to load and sometimes need to be tapped multiple times. Probably an iphone focused app that has put android users on the back burner unfortunately
