Our Android app software is optimized to work on contemporary and widely used Android devices running android 4.0 and up! However, many manufacturers extensively modify the Android OS for their own devices and our apps may not work on them (e.g. Amazon Kindle and Barnes & Noble Nook devices).
Note: Here is a list of supported devices from Google Play
If you have a device that our apps are not working on or that's compatibility you are unsure of, you can email firstname.lastname@example.org with information about your device and the OS it's running and we can verify compatibility.
