overall very accurate. whether it be predicting how I'm going to feel or other things like that, it's very helpful. one thing I don't like is how you have to pay for half of the features. don't get me wrong, if a had the money I 100% would buy premium because it is definitely worth it, but I don't have the money so unfortunately I cant. Great app though, would recommend as a period tracked!

App is great for tracking moods, periods, and many other symptoms that helped me understand my body better. I had premium for a year or two and the advice didn't really change or was specifically tailored to me. I stopped premium and now when I click on content I'm not allowed to see anything, even though I thought some of it was basic health knowledge.

Currently testing the free trial, and I am impressed so far. Love the extra resources, articles and message boards, which creates a great sense of community. My only constructive feedback is that it seems very American (references to OBGYN etc.), options for other countries and their terminology might be a good addition?
