This app works okay if you would like it to predict when you ovulate. For those of you who know because you are taking your Basil temp, the chart is too tiny to track and the program wont let you say when ovulation occurred on the calendar. There is a way to state average luteal phase but it applies it to each month. I am happier with womanpro. I plan on deleting this app.
