What Can You Test?

🔘 All Buttons

Every face, shoulder, trigger, D-pad, stick click, and system button highlights the moment it's pressed.

🕹️ Analog Sticks

Real-time XY position shown as a moving dot with numeric readout and circularity error per stick.

📉 Stick Drift

Release all sticks and watch for non-zero values. Above 2% may indicate hardware wear.

📳 Vibration

Test left and right rumble motors with heavy, light, burst, and pulse patterns (Chrome/Edge on Windows).

⚡ Input Latency

Estimates round-trip detection time in ms. Great for comparing wired vs Bluetooth lag.

🎮 Multi-Controller
