Knock on your MacBook to control your Mac
Knock is an innovative Mac utility that leverages the built-in accelerometer in Apple Silicon MacBooks to turn physical taps or knocks into instant, customizable actions. Designed for productivity enthusiasts and power users, it transforms simple physical gestures into commands like switching tabs, changing desktops, controlling music playback, opening apps, or running scripts. Unlike traditional keyboard shortcuts, Knock offers a more intuitive and tactile way to interact with your Mac, making multitasking quicker and more seamless. Its unique use of hardware sensors sets it apart, allowing users to perform actions with a natural, physical gesture on the MacBook's chassis or nearby surface, without interrupting their workflow.
Pros
- Utilizes built-in accelerometer for innovative gesture controls
- Highly customizable shortcuts and actions
- No additional hardware required beyond the MacBook
- Enhances productivity with quick, physical gestures
- Easy to set up and use
Cons
- Limited to Apple Silicon MacBooks with accelerometers
- Requires precise knocking to trigger actions, which may need adjustment
- Potential false triggers if knocking is inconsistent
Best for
- • Switching between open tabs or desktops with a tap
- • Controlling music playback during work or workouts
- • Opening frequently used apps with a simple knock
- • Running custom scripts for automation tasks
Pricing: Likely operates on a freemium model with basic features available for free and premium features or customization options offered via paid plans, typically starting around $5-$10/month.
