You certainly can!

Simply Piano and Simply Guitar are available on mobile/tablet devices (we do not have a desktop version).

Once you install the app on an additional device, make sure to press the ALREADY A MEMBER button on the opening screen of the app.

Then, enter the email you used previously, in order to continue.
