Confusing

Tried typing in my known period dates to get it ready to make menstrual and ovulation predictions but couldnt figure out how to save. Found period tracker lite and menstrual calendar apps for iPhone to be better and easier to use. There wasnt anything to explain how to use and for most apps I can usually figure them out w/ out directions but this was frustrating. Dont recommend.
