Test and calibrate your PS5 DualSense, PS4, PS3 and Xbox controllers online. Detect stick drift, check joystick accuracy, and diagnose button or trigger issues in real time. If drift shows up, the stick module is worn - and we can fix it.
🔒 Everything runs locally in your browser - nothing is recorded or uploaded.
Connect your controller by USB or Bluetooth to this device.
Wake the controller so your browser detects it - you'll see it light up below.
Move both sticks in full circles and watch for drift, off-centre resting, or dead zones.
Steady centre = healthy. Wandering input at rest = drift that usually needs a TMR upgrade.
Test drift, dead zones and buttons on the go - free on Android.
Stick drift is when your controller registers movement even though you're not touching the stick. It's caused by worn potentiometers inside the analog stick module. Our tester shows it instantly as input that won't settle at centre.
Yes. It works with PS5 DualSense, DualSense Edge, PS4, PS3, Xbox Series X|S, Xbox One, Elite Series 2, SCUF and most third-party controllers, over USB or Bluetooth.
Completely free. It runs in your browser - nothing to install. There's also a free OG Gamepad Tester app on Google Play for on-the-go testing.
Drift means the stick module is worn. A permanent fix is a TMR (magnetic, contactless) upgrade that eliminates physical wear. We can repair or upgrade it - mail-in from anywhere or drop off at our London workshop.
Browsers only expose controller data to a page you've interacted with, using the standard Gamepad API. Nothing is recorded or sent anywhere - all testing happens locally on your device.
A TMR upgrade replaces worn sticks with magnetic, contactless sensors - drift-free for years. Mail it in from anywhere or drop off at our London workshop.
