Meet Knucklebop

Knucklebop uses the motion sensor in an Apple silicon MacBook to turn light taps into shortcuts. Tap the palm rest or nearby desk two to six times, and each tap count can trigger a different action. Rules can vary by application or website, with general actions for everything else. You might mute a meeting, control music, switch desktops, or open a menu of additional commands. Power users can connect taps to Shortcuts, AppleScript, or shell commands. An on-screen indicator confirms the action, while isolated bumps are ignored. The app runs on macOS 14 or later and offers a trial followed by a one-time purchase.
