Description
Knock turns taps on your MacBook into instant actions. Switch tabs, change desktops, play/pause music, open apps, run custom scripts, or take screenshots - all with a simple knock. Tap the desk beside your laptop or knock on the MacBook’s chassis (not the trackpad). Knock uses the built-in accelerometer in Apple Silicon MacBooks to trigger customizable shortcuts.

Could you build this?
Partial While macOS menu bar apps are straightforward, tapping into undocumented private IOKit APIs to read low-latency Sudden Motion Sensor (SMS) accelerometer data reliably on modern Apple Silicon Macs requires specialized low-level systems engineering.
What it would actually take: A developer needs Swift/Objective-C with low-level IOKit/CoreFoundation bindings to read Apple accelerometer hardware registers. On Apple Silicon, accessing raw internal sensor data is restricted and undocumented, requiring reverse-engineered private frameworks and continuous calibration algorithms to separate accidental desk knocks from typing vibrations without draining battery.
