We've practiced Natural Family Planning for a year and a half so charting was part of how we avoided pregnancy and now that we are TTC it will be part of how we get pregnant. We use the Sympto Thermo method (STM). I started using the online TCOYF charting tool but found it cumbersome. We use Ovu-view App on Android now and we love it.

What charting method are you using? Are you using any iphone or android apps?
