You can install and evaluate the demo (lite) version on as many devices as you like.
Synthesis App Full Version
The license agreement permits the user to install the App on two personal devices on the same platform, for example an iPad and an iPhone.
If you wish to use the app on a new device, you will need to uninstall the App from one of the other devices.
After the App has been uninstalled, contact support and mention which device you are no longer using. Support will deactivate this device and you will be able to install the App on your new device.
If however you also have a mobile device with a different platform (for example a Windows 8 Phone from the Windows store), then you will need to purchase the Synthesis App again for that platform type.
