● Runs on your device; nothing is uploadedHow to use it

- Click each button many times; suspect double-clicks are listed with their gap.
- Scroll up, down and sideways over the test area to check the wheel.
- For DPI, enter a distance, click Lock pointer and measure, move that far along a ruler, then click.
