Ratings and reviews

it's been a helpful app for me for tracking my period over the years and seeing how things change. However the user experience is pretty bad. it's very laggy, and whereas before I could enter all my data on one screen, it now takes several taps (with lag on all of them) to enter my temperature data and then my period data. it's the little things we do every day that either create enjoyment or frustration, and this has been a small source of frustration for me.

The app suddenly logged me out and won't let me into my account without forcing me to pay ANOTHER annual fee. I paid my full fee in February and have 7-8 months left. I'm selecting the login to my account option and it's treating me like I'm a new account. There is no way to bypass the selections and payment screen. Overall been good at predicting ovulation but the algorithm is off. It started to show ~3 weeks of green days and changed to barely a week of green days with no explanation.

I have recently been having problems where the app changes my period length. it will automatically add a period where there wasn't one or extend a period that wasn't extended which throws off my ovulation and everything. I've had to fix it 3 different times now. for how much this app is I shouldn't be having issues like this. and considering this is my form of birth control it won't work when the app keeps adding periods that I didn't have an messing with my predicted ovulation.
