Not Working – FitRPG: Gamifying Fitbit Review

I downloaded the app because I'm very excited for what it has to offer. Unfortunately the app isn't working. When I try and sign into my Fitbit account a weird message with a white screen comes up that only goes away if you close the app. I have tried logging in again, with the same result. Please fix.
