Simple, accurate, and in control

I love using Lily. My husband and I have been using it for over 3 years to both successfully avoid and plan pregnancy. I love that it is simple and easy to use and I feel like I am in control of my fertility. I would, however, recommend taking an NFP course in addition to using this app if you are seriously considering using Lily to avoid pregnancy.
