This app works
I became pregnant after using this app for one month, which came after TTC for about nine months. It helped me pinpoint my ovulation date (Day 19), which the period app I had been using previously did not do, and it offered tons of great tips for improving fertility. I highly recommend it in conjunction with BBT charting, using OPKs and monitoring CF.
