Device Tests

Measure the interval between clicks and check whether double clicks register reliably.

Inspect connected controller buttons, triggers, axes, stick drift, and vibration support.

Measure simultaneous key detection and identify combinations your keyboard may not register.

Check every physical key and see pressed and tested keys on a full keyboard layout.

Estimate mouse event frequency in hertz while you move the pointer across the test area.

Test left, right, middle, side buttons, wheel scrolling, and pointer movement.

Verify headphone channel placement with separate left, right, and stereo test tones.

View a live waveform, input level, peak, and dominant frequency from your microphone.

Record microphone audio locally, play it back, and download the recording.

Use your front camera as a private mirrored preview and save a snapshot when needed.

Play a short tone through the left, right, or both audio channels.

Preview a camera locally, inspect stream settings, switch devices, and take a photo.

Cycle fullscreen solid colors to make dead, bright, or stuck pixels easier to spot.

Inspect grayscale, RGB gradients, color bars, contrast, and banding by eye.

Estimate display refresh rate and frame timing variation from browser animation frames.

Inspect screen size, browser viewport, pixel ratio, color depth, and orientation.

Open solid colors, gradients, color bars, and grids in fullscreen for visual inspection.

Inspect live acceleration including gravity along the X, Y, and Z axes.

Read device orientation angles and visualize rotation after explicit permission.

Visualize active touch points and measure the maximum simultaneous contacts detected.

Trace across a fullscreen grid to check touch coverage and unresponsive areas.

Check browser vibration support with short, long, and patterned feedback.
