What it does

• Polling rate up to 8000 Hz: real rate, jitter, percentiles, interval histogram and timeline.
• Sensor: missing packets, spikes, dips and reversals on a zoomable path; angle snapping detection.
• DPI: guided measurement in passes over a known distance.
• Clicks & wheel: chatter, hold time, wheel notches, reversals and tilt.
• Movement on click (new): how many counts the sensor reports when you click with the mouse still. A good mouse reports 0.
• Export of a text report and of the raw polling intervals (CSV).
• 8 languages: English, Italiano, Русский, Español, Français, Deutsch, Português, 中文 (简体).

Notes

• At 4000-8000 Hz use a high DPI (1600+): the rate is only measured while the mouse moves fast enough to report in every poll.
• Bug reports with an exported report from your mouse are very welcome, as are translation fixes from native speakers.
