Gamepad Tester

Gamepad Tester shows exactly what your controller is sending to Android. Button presses, stick positions and trigger values appear immediately. If a game does not respond as expected, you can quickly tell whether the fault lies with the controller or with the game.

The controller connects over Bluetooth, USB-C or OTG. There are four test modes: a native Android mode, two PlayStation-style layouts for different button mappings, and a universal mode for any device, with numbered buttons and raw axis values. Separate hardware tests cover vibration, where each motor can be run on its own with adjustable strength, and the gyroscope and accelerometer when the controller has them.

It suits people choosing a gamepad, diagnosing a fault or checking a button layout. No account or setup is needed.
