Super useful. Thanks a lot. It helps me very much. Initially I didn't even see how many useful features it has. ex:I calculate manually by count days between my starting days of menstruation to see which is my cicle length...then, when searching on diff tabs, I saw that there was already an cycle history option. Predicts correct the days of starting menstr, everything is fine. The little ads are showing only at the bottom not interfering and on exit. I dnt hav engh space t say how much I like it

I love the app. It has been helpful. I don't know if the app currently store the info recorded on it so that a user can get the data whenever they need it. I recall using the app some years back and after a while i stopped, only for me to download and start using it again with same login detials as the old one but i couldn't find my old records. I was quite disappointed.

I used this for years, recommended it to others cus it predicted accurately once u input ur first date. But recently, it's grossly inaccurate! It'll tell u ur period is 8 days late for a just-concluded period! After series of messages with the devlopers and screenshots, they still maintained I'll have to manually input the date for each period every month! If that's the case, I DEFINITELY DON'T NEED THIS APP! I might as well track it manually on a calendar by myself! Safe urself some headaches!
