About GamePad Tester

GamePad Tester helps gamers and developers quickly check whether a controller is working correctly. Whether you’ve just bought a new gamepad, picked up a used one, or you’re troubleshooting drift and dead buttons, our tools let you see every input in real time — buttons, analog sticks, triggers, and vibration.

What We Build

• Gamepad Tester (Android app) — real-time testing for buttons, sticks, triggers, and vibration, with Universal Mode for Xbox and PlayStation controllers.
• PS Controller Tester (Android app) — focused testing for PS4 DualShock and PS5 DualSense controllers.
• Gamepad Tester Lite (Android app) — a lightweight version for quick checks on lower-end devices.
• Online Gamepad Tester — a free in-browser tester (no install) available at gadgetester.com for desktop users.

Why We Built It

Controller problems are frustrating and hard to diagnose — is it the controller, the cable, the Bluetooth connection, or the game? We built GamePad Tester to give a clear, instant answer. By showing raw input data (vendor/product IDs, mapping type, axis values, button indices), our tools help you confirm in seconds whether your hardware is healthy before you blame a game or return a device.

Our Expertise

We test controllers daily across Android, PC, PlayStation, and Xbox. That hands-on experience shapes both our apps and the guides on our blog, where we cover stick drift, button mapping, input lag, Bluetooth pairing, and more — written from real testing, not guesswork.

Privacy First

Our apps process all controller input locally on your device — button presses, stick positions, and vibration tests are never transmitted or stored on our servers. See our Privacy Policy for full details.

Who’s Behind GamePad Tester

GamePad Tester is built and maintained by Selva Sundar (s2digital). Our apps are available free on Google Play.
