I am writing this assuming this app will be available for other devices.
On the first start of the app, it should check which device it is on or the user chooses it. And by doing this it should operate accordingly. It should change the UI to fit the screen and the shown content should be only for that specific device.
Process example:
App boots --> It checks the device --> askes the user if its the right one --> yes/no
If yes it does what it should.
If no the user can choose the correct one.
