Apple: Trusona will run on iPhone5s and newer devices and requires the iOS to be 10.0 or higher. Trusona will also run on iPad air 2 or newer devices.
Android: Trusona will run on version 5.0 (Lollipop) and higher.
If any devices are jail-broken, rooted, or do not pass the Trusona safety checks than the Trusona app will not run on a mobile device.
A new out of the box Android device may not be running google approved Android. Some phone manufacturers may put custom firmware on their Android devices which may result in the device failing Trusona's SafetyNET checks.
If you are unable to add a credit card to Google Wallet on your Android device you are most likely unable to set up Trusona since they both use the same safety checks.
