Knock
A Mac shortcut application that uses the Mac's built-in accelerometer to sense tapping vibrations and thereby trigger shortcut actions, without requiring additional hardware.
Timeline (last 90 days)
Knock is a shortcut app that triggers shortcuts by tapping on a Mac laptop's chassis.
Knock uses the Mac's built-in accelerometer to sense tapping vibrations, requiring no additional hardware.
Knock was developed by Arianna I.
Knock received 67 votes on Product Hunt, ranked 20th for the day, and is categorized as a productivity tool.
Knock needs signal processing algorithms (such as threshold detection, band-pass filtering or machine learning classifiers) to distinguish valid taps from ambient vibration noise.
Different MacBook models have different sensor locations, sensitivities and chassis structures, so Knock's algorithm needs model-specific adaptation.
Knock is suited to high-frequency, lightweight operations such as taking screenshots, opening frequently used apps and muting.
In mobile scenarios (such as using it on your lap or in a cafe), tapping the chassis may be inconvenient and prone to accidental triggering.
The Product Hunt page does not disclose which macOS versions Knock supports or how many configurable tap types it offers.
