Pebble Data Logging has stopped

Dear Joshua,

I have installed the app on my Sony Xperia S, running on Android 4.1.2, but when I try to open it, it gives the error 'Pebble Data Logging has stopped'. I also installed it on a Sony Xperia z3 (Android 5.1.1). On that phone it does work. Do you have an Idea what causes this?
