About Gamepad Test App

Browser controller testing made simple and accessible

Our Mission

Gamepad Test App was created to help players check their controllers before problems show up the hard way during a match or after a trip to a repair shop. The goal is simple: make controller diagnostics fast, browser-based, and easy to understand without requiring special equipment or technical setup.

Who Runs This Site

Gamepad Test App is built and maintained by Furqan, a web app developer who has also developed two Android apps. I built this tool because controller problems are often noticed too late: when a stick starts drifting in-game, a trigger does not reach full range, or a button starts behaving oddly.

I personally use a PS5 DualSense controller, though lately I have had less time to play than I would like. That is part of why this project matters to me: when gaming time is limited, a quick browser test can help confirm whether the controller is ready before the session starts.

The repair and troubleshooting guides are updated when I learn something useful from controller testing, browser behavior, online research, or conversations with friends who run into real controller issues.
