I’ve been using the app for seven or eight years now. I love it for its clear and intuitive functionality. I use it all the time, and it really helps me answer my gynecologist’s questions with confidence during appointments. Plus, over the past year with the premium subscription, I’ve been able to understand how my mood and physical state shift throughout my cycle. The cycle forecast feature in premium is absolutely brilliant. Thank you so much!

Constant bugging.
Goda_.
I’ve used this app for as long as I can remember, probably around 8-9 years. And the main problem that continues is constant bugging and lagging. I always have to close the app and reopen it to continue putting my information. I can’t even open a calendar to see dates without lagging. I thought that maybe it was my phone’s problem, but it continued as I changed phones to newer models. Please do something about it. Second problem is pop ups. I understand the need to promote your bussines and everything is alright with it. But pop ups plus constant lagging makes this app super anoying. Sometimes I can’t do anything in this app because it lags on a pop up. I would change apps but sadly, this app has many years of my period information and I don’t want to lose it. I still have hope you fix this.

Too much pop-ups.
kk_rev
Good app, using it about 4 or more years, everything was good, but then devs decided to add millions of features and pop-ups that you can’t just turn off. This became annoying and uncomfortable as hell. it would be good to have a choice of the list what you want to use in the app / or simple version for those who just want to control periods without “don’t you wanna read about all the joy of your periods?” -No, God, no. For annoying ads I would give 1star, but devs and designers worked too much and hard to make them happen so I have to appreciate the job. Same time, with these ads I want to throw my phone in the river screaming like a seagull how much I hate the updates, so please, guys, do something with it😀

everything changed to worse

I have been using this app for about 5 years, and it was amazing, I was talking with everyone about it. I was reading forums, I always checked the chances of getting pregnant, symptoms and so on. Now I can’t do any of that, because I don’t have premium account. at this point the app is useless ( if you are not willing to spend money). If you are thinking of downloading it because its free, don’t since its almost not. If it didn’t have the data about my period dates I would just delete it and download another one. Not only that its practically useless-the non stop pop ups about premium account are so annoying too.. I really used to love it, but I guess nothing is free anymore..
