This app was great for months but now it is not working properly and there have been no updates to fix the bugs. It no longer says shows my badges for challenges I have completed but permanently shows completed challenges as Day 1 on the dashboard. Anytime I click one of them the app shuts down. Closing and reinstalling the app have not helped. Until this bug is fixed the app is very annoying. If it worked properly it would be one of my fave apps for workouts.
