Don't just test your controller. Diagnose it.
Run a guided check for resting stick movement, joystick consistency, trigger range and button response. InputSure reports what your browser observes instead of hiding the measurements behind a vague pass/fail score.
Start broad, then investigate.
The Health Check is the fastest first step. Focused tools expose more detail when one component deserves another look.
Controller Health Check
A guided sequence for idle sticks, left/right outer traces, triggers and standard digital buttons, ending in one component-level report.
Live↗Gamepad Tester
Watch browser-observed axes and buttons respond in real time.
Analog stick↗Stick Drift Test
Measure repeated resting displacement, jitter and directional bias.
Analog stick↗Deadzone Test
See what simulated software deadzone suppresses observed idle movement.
Analog stick↗Circularity Test
Trace the outer edge of either stick and inspect radial consistency.
Triggers↗Trigger Test
Compare observed resting values, peak range and repeated pulls.
Buttons↗Button Test
Confirm presses, releases and repeated activation across visible controls.
From suspicion to useful evidence.
Connect
Use USB or Bluetooth and press a controller button so the browser exposes the device through the Gamepad API.
Run the guided check
Follow the prompts. The site samples resting sticks, outer traces, trigger pulls and button responses, then confirms borderline resting-stick readings when needed.
Investigate anything unusual
The report links to focused tests instead of treating one short run as a manufacturer-level diagnosis.
Measurements first. Verdicts second.
InputSure intentionally distinguishes browser-observed behavior from direct electrical or laboratory measurement. That means clearer language, visible metrics, a second sample for borderline stick readings, and retest recommendations when evidence remains incomplete or contradictory.
