Great app, easy to use
I had been using another ovulation app for about 12 months while trying to avoid pregnancy. I started using this app in July 2016 and input 6 months of data from my old app into this app and was pregnant on the first try. I like the simplicity of this app, especially the red indicator for "no sex days" and green indicator for "sex days." The app is very easy to use. I tracked all variables except temperature. I also found the information section of this app to be very helpful, providing simple explantions about ovulation, fertility, and sex determination. I will definitely use this app again!
