I need period diary to track my ovulation cycle automatically owing to my busy day to day schedule so that there is no need to mark my calendar with the start and end date of my periods manually but this app is similar we need to end the period manually which most of the times I tend to forget, there is no option to start/end it on a previous date nor does the app calculate my periods end date based on the information given by me while registering. Can't believe I spent 4000 bucks on this

I'm an old user of this app, and it was very comfortable in use, but after the effective management started to force you go premium, it is impossible to track you period without seeing all those bottom sheets and other advertising. If it was one, I wouldn't mind, but they go one after another. I left the in-app review, noone has connected to me.
