Great for period tracking/predicting, bad for fertility

This app is great for tracking and predicting my period. Im not on BC and yet my period always arrives as predicted. This is great, because I can rely on this app when Im planning vacations several months out as the app predicts the next 12 cycles.

I will say, however, that is is not good for predicting fertility. For the past 4 months, I have been using an OPK and this month I started also using a fertility monitor. Both tell me that I ovulate more than a week after the end of what this app predicts to be my "fertile days."

If you just want to track/predict periods, this app is perfect. When youre ready to try to conceive, get an OPK or a fertility monitor.
