I built it because I kept fumbling for the mute button mid-call. Every Apple Silicon MacBook has a motion sensor that nothing uses, and it turns out it can feel a light tap on the palm rest, or on the desk right next to the laptop.
No rhythms to learn: only the count matters. Two taps mutes your mic (using Zoom's, Meet's or Teams' own shortcut, so their mute button stays in sync), three plays your music, four opens a menu of as many actions as you like. Each app or website can have its own taps.
A few honest notes:
It needs an Apple Silicon MacBook on macOS 14 or later. The 7-day free trial is the easiest way to check yours.
It reads the sensor through an undocumented macOS interface, which is why it isn't on the App Store. It's signed and notarized, and if a macOS update breaks the sensor, the app tells you instead of failing silently.
Sensor data never leaves your Mac. No analytics, no account.
Try it free for 7 days, then it's $12.99 once (or $19.99 for 3 Macs), with a 14-day refund window: knucklebop.com
I'll be here all day answering questions. What would you map to five taps? 🥁
