You can open your progress in Simply Piano on multiple devices by logging in with the same email address you used previously. This includes both Android and iOS devices.
Once you install Simply Piano on the phone/tablet, make sure to press "Already a Member" just below "Get Started" on the opening screen of the app. Then, enter the email you used before for Simply Piano to continue.
*If you see Anonymous on the 'My Account' page, this means the account was not linked to an email address and you will not be able to open your progress on another device. Just press the pencil (iOS) or click Change Email (Android) to change this to register with an email and you will be able to use your account on another device.
Have more questions? You can talk to us through the app. Tap on Menu > Settings > Have a Question? :)
