Can't log in – Stark Fitness Review

I got this to try out before spending $5 on one of the other apps I wanted. However, I can't get past the login screen. When I attempt to log in with Facebook it doesn't do anything, like I never even pressed login. If there is a glitch such as this, I can't take a chance on a paying app.
