I've use it for some good years, but now I can't login..and don't even allowed you to put your email address, it's going straight to login with Facebook, and that's one doesn't work, I used it with my email address. Before you guys doing any updates, make sure that everything it's working properly. Otherwise you will loose your users. Me definitely I will uninstall the app as a can't use it.

Since its update it has erased all my entries. Its a little sad for me as I had been doing this for years and from my two pregnancies so it was nice to have the dates. I now have to uninstall this app and continue with another as it has my most recent dates and predicts better due to this. I do not want to have to start again. Maybe it should have been made optional to update. Not everyone likes changes. They did try to help but it seems I'm not the only one to lose data. (13.4.21)

Awful!! I've had this app installed for several years and it was my favourite tracker. Now it's been completely changed and looks so different. It's harder to use and I absolutely hate it!! Looking for a new replacement so I can delete this one after all these years. I'm going to lose all my tracking records as well. If it's not broken, leave it alone.
