About Knock

Knock is a macOS utility application that detects physical taps made on a MacBook's chassis and translates them into programmable shortcuts. The app works in the background, listening for tap patterns and triggering user-defined actions, allowing for hands-free control without needing to touch the keyboard or trackpad. It appears to be designed for users seeking to streamline their workflow or improve accessibility, offering a novel input method using the laptop body itself.

Targeted at MacBook users, Knock aims to enhance productivity by enabling quick access to frequently used functions through customizable tap sequences. The app's exact feature set and configuration options should be verified through its official documentation, but it likely supports a variety of tap patterns and action mappings. As a free application, it may offer full functionality without immediate costs, though any premium tiers or limitations should be checked on the product's website.
