- On the device you want to install the upgrade, start SimpleMind+
- Inside SimpleMind+ open the help screen by touching the (?) button.
- In the help screen you will find a button named "Restore Previous Purchases".
- Click the "Restore Previous Purchases" button and wait at least 30 seconds for the App to contact the app store.
- The app store will then tell the app that you have purchased the app and "Full Functionality" will be activated.
- This will NOT cost you any money !
Note: Login to the same iTunes account as you used when you originally purchased SimpleMind+
