The app was amazing when I initially installed it years ago, but nowadays EVERYTHING but the calendar is locked behind a paywall. Oh, this article that would be extremely helpful to read right now while in a state of worry? Pay for it. This simple assessment to get an overall idea of something? Pay for it. Want to view ESSENTIAL female health related questions?? PAY FOR IT! So much for making it accessible to women! Everything requires payment! I'll go back to a paper calendar soon!

The app is good for tracking things, but I don't think I'm going to use it anymore. I wanted to start the free trial and it ended up making me choose a subscription (which I've since cancelled). I only wanted the free trial to check one post, but now I'm £28.99 down the drain for something I don't plan on using long term. It's just my mistake, but it has left a bad taste in my mouth :(

I love everything about this app. It's really accurate and it provides helpful tips and information. I wish the sync with google fit would work (sleep, period, weight) but for some reason at least for me it doesn't. It would also be very helpful if water intake and other stuff like that could be synced with apps like samsung health or health sync! Edit: A dark mode option would also be very helpful!
