Nice app... When it works
I have the app on iOS and, overall, I consider it a good app, which helps you manage your plan properly. One really bad thing is that you can use it only through your data plan, hence, if you run out of data is basically impossible to access the app to boost your data. I lived in several countries and this happened to me only with Virgin UAE. Besides, 50% of the times the app crashes... Instead of investing on me features, focus on stability first please.
