Could be better

The old version had a better outlook. The functionality can be improved and the app to be easier to work with, e.g. a list of all options.

I loved It until I got pregnant

I’ve been using this app for years and I used to love it but now that I got pregnant the app is just not working for me. It doesn’t calculate my due date right and It continues to predict my menstruation. I wish it had a better pregnancy mode! Otherwise it’s a great app!
