Not worth the money

I chart, so I know exactly when its go time. Ive been comparing it to fertility friend, and this app is always off by at least 3-5 days for O day. Which if youre trying to make a baby, doesnt work. If you want to track your periods, its a fine app, but I wouldnt use it to plan a pregnancy.
