MacSlapApp makes your MacBook react when it gets a sharp impact. It can shake the screen, flash brightness, play a voice line, and trigger haptic feedback. It uses the built-in motion sensor and works from the menu bar.

MacSlapApp includes seven voice packs with different tones. You can switch packs from the app menu. Use a calm voice if you want a mild reaction, or choose a louder pack for a stronger response.
MacSlapApp watches for impact signals from the MacBook hardware. When it detects a hit, it can run several actions at once:
- shake the screen
- flash the display
- play sound
- trigger haptics
- show a reaction in the menu bar
It uses Swift and system-level macOS access to keep the response fast.
You can adjust the app from the menu bar:
- set impact sensitivity
- turn screen shake on or off
- set brightness flash strength
- choose a voice pack
- enable or disable haptics
- mute audio output
- start the app at login
Use a light tap during setup so you can test the response without stressing the hardware. Pick one or two effects first, then add more if you want a stronger reaction.
