Controller Health Check
One guided run for resting stick movement, left/right outer traces, trigger range and button response. The report shows what the browser observed and recommends focused retests when the evidence is incomplete.
Connect by USB or Bluetooth, then press a controller button.
Connect your controller
Connect a controller and press any button. A standard browser mapping is recommended for the complete guided test.
A pull counts only after the trigger rises substantially and returns to rest. If a trigger cannot complete five pulls, the report keeps the run incomplete rather than guessing.
Controller Health Report
This report is based on browser-exposed Gamepad API values. A warning means the result deserves attention or repetition; it is not automatically a manufacturer-level hardware failure diagnosis.
