A repair bench that does not need a shop PC

Pro repair tools are not screenshots of a test. The touch test records the cells you actually tap. The display test fills the screen with solid colours. Speaker uses the Web Audio API. Microphone and camera use getUserMedia and stop the tracks when you leave the page.

Vibration uses the Vibration API and says so when the browser, usually iOS Safari, does not implement it. Motion sensors ask for permission on iOS instead of failing silently.

These tools grade the hardware in front of you. They do not upload audio, video, or touch traces.
