How to Get Started

Just three steps to run a complete controller test and understand your controller's health status.

01

Connect Controller

Connect your controller to your computer via USB cable or Bluetooth. If the browser doesn't respond, press any button on the controller to activate the connection.

02

Button Detection

Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.

03

Sticks & Vibration

Rotate the sticks to check linearity and drift issues; click the vibration test button to feel if the left and right motor feedback is working properly.

What would you like to do next?

Complete Controller Hardware Diagnostic Guide

A drifting stick or a button that misses presses — run the full diagnostic and pin down the exact fault before you spend money on a replacement controller.

What We Check in the Unified Dashboard

  • Analog Stick Center Offset: Detects microscopic voltage variance in resting thumbstick potentiometers.
  • Circularity Range Error: Verifies whether your thumbsticks reach 100% full diagonal displacement.
  • Button Matrix Ghosting: Ensures all face buttons, shoulder bumpers, and D-pad inputs trigger independently.
  • Trigger Linearity Curve: Tests whether analog triggers increase smoothly from 0% to 100% without dead spots.
  • Haptic Rumble Actuators: Triggers dual heavy and light vibration motors to test motor health.

Frequently Asked Questions

Everything you need to know about testing your controller.

How long does the Full Diagnostic take?

The complete diagnostic takes approximately 2 minutes and tests analog stick drift, circularity error, button response matrix, trigger linearity, and vibration rumble motors.

What is the Controller Health Score™?

The Health Score is a 0–100 proprietary algorithm that combines drift percentage (30%), circularity (20%), button response (15%), trigger linearity (15%), vibration (10%), and polling rate (10%) into a letter grade from A+ to F.

Does this test require any software or driver downloads?

No. The entire test runs locally inside your web browser using the standard Web Gamepad API. No software or extensions are required.

How this test works & its limits
  • This test reads your controller through the browser's standard Gamepad API — no drivers, no installs, nothing leaves your device.
  • Readings depend on connection mode: Bluetooth reports at lower rates than USB. Compare like-for-like (wired vs wired).
  • We measure the input reaching the browser — display lag and game-engine queues are outside this test's view.
  • A clean reading now does not guarantee no drift in-game: deadzones differ per game, and wear develops over time. Use the Drift Timeline to track yours.
  • This is a diagnostic, not a hardware-lab certification. For repair or RMA decisions, confirm with a second run or second tool.
