The more past periods and info u put in the more accurate it will be
This app is not that accurate for me. It originally said my period should start today. It hasn't so the date has been moved until tomorrow. App automatically moves date. It shows my ovulation earlier than I acctually ovulate as well. I know this bc I take at home ovulation tests. So I'm not impressed w app. I use it to keep track of cycle and that is about it.
It is for me my cycle is every thirty days last five days ovulate on day 16
