Brilliant Does exactly what it is designed to do. Perfect for preloading a cycling route into and downloading the map data so that when on the move the data is already there and battery drain is minimal.
Technical revision only, moving development to Android Studio and compiling for lollypop/marshmallow.
Please check you can upgrade to the current Google Play Services (do this first). Google Play Services is getting quite large and may be too big for some older phones.
