Apple: Trusona supports 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. 

For security purposes, jail-broken devices are not supported with the Trusona app.

Android: Trusona supports Android devices running version 5.0 (Lollipop) and higher.

For security purposes, Trusona will only work on Android devices that passes Google's SafetyNet checks. Google uses the SafetyNet to determine if an android device has been tampered/rooted and if it is running a licensed version of Android. 

A new out of the box Android device may not be running a licensed version of Android. Some phone manufacturers may put custom firmware on their Android devices, which may result in the device failing Google's SafetyNET checks.
