True, I recommend an xbox x/s controller and this cheap but great mount

$10 + a used xbox controller + your phone and you have a gyro capable (your phone) mobile gaming system with probably the best gamepad ever.

I don’t think this takes the place of a gadget like the Brick Hammer but I do HEAVILY recommend going this route first as you likely already have an adequate phone and xbox controllers are cheap and plentiful on the used market (and their only real achilles heel is they don’t have gyro… which your phone solves).
