Transferring your account—including your health schedule, history, and points balance—is easy. All you'll need to do is make sure you've registered your account on your existing device. To do this, enter your 'Settings' and make sure you see your email address listed. (If you don't see your email address, tap 'Register' to create an account.) To access your 'Settings’ tap the 'Profile Icon' on the 'My Health' tab, then tap the 'Gear Icon' and tap 'Settings'.
Once you have an account, open the app on your new device, and go to 'Settings' then 'Login'. After you submit the email address and password you originally submitted to create your account, your data will be restored.
