Calculate your controller's overall hardware score from 0-100. Diagnostic grade based on stick drift, circularity, button matrix, triggers, and polling rate.
Please connect your gamepad via USB or Bluetooth and press any button to begin the diagnostic wizard.
Leave both analog sticks completely untouched. Do not move them.
Press each of the highlighted buttons to verify their response.
Squeeze L2 and R2 all the way down to 100%.
Here is your official Controller Health Score™
Analyzing test data.
Zero drift, flawless circularity, 1000Hz response capability. Ready for competitive play.
Minor drift or trigger wear manageable with 5% deadzone adjustment.
Potentiometer replacement or deadzone tuning needed immediately.
Just three steps to run a complete controller test and understand your controller's health status.
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.
Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.
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.
Select a diagnostic calibration suite, deadzone analyzer, or high-frequency overclock tool.
Calibrate zero-point offsets or follow step-by-step repair guides.
Calculate exact radial vs axial deadzone overlays for Fortnite, Apex, & COD.
Verify true hardware polling Hz stability and statistical circularity grades.
Turn your test results into skill. These arcade games train the exact inputs you just measured — drift, buttons, triggers, D-pad and reaction time.
Hardware wear occurs gradually over hundreds of hours of gameplay. By tracking your controller's Health Score over time, you can catch potentiometer drift and button degradation before it affects tournament matches or ranked competitive play.
Everything you need to know about testing your controller.
The score is calculated using a weighted formula: Stick Drift (30%), Circularity Error (20%), Button Matrix Response (15%), Trigger Linearity (15%), Polling Rate (10%), and Haptic Vibration (10%).
