Numbs does the sum on Android.

To run Numbs on your Android device, the minimum required is only the OS 2.2. The Android application runs just as well as the iPhone app but with some minor difference which we will look into now. Firstly, in the Google Play app, the “back” button is not necessary, so we hid it. With this version of the application, it’s also not necessary to display the “restore purchase” button. The app restores user’s purchase automatically when the user launches the title. Finally, on Android, when the user wants to purchase the premium version, there won’t be a confirmation pop up but a “Google wallet” page. At the end, your challenges remain unchanged!
