Way too expensive for the quality

I used to have the free version of this app that predicted not only your next period, but up to a few months in advance. I upgraded to the paid one, despite the high price, but quickly found out that this version predicts only your next period. There are free ones (FMC, iMensies) that have a calendar and can predict months in advance. Try those out, not this one.
