Guys, who are we kidding? How often have we thought about this topic but never actually felt confident in the subject?

I am talking about your girlfriend’s, wife’s or just friend’s menstruation cycle. This little tool here shows precisely when the next period begins, ends, when her fertile days are and even the day of ovulation. This whole subject is obviously not simply solved with a tool like this. Mother nature does not just work 100% the same every single time – at least that’s what I read about this subject.

Anyway, the only two things you need to enter in the application is the last start of the cycle and the cycle duration. And that’s it. You will know precisely when your partner is fertile or when you should think about getting her some flowers in her moody phase. 

If you want to have this app, just download it for free:
