How it works

Three taps to set up.
Zero to remember.

01

Pick a knock

Single, double or triple. Or record a rhythm of your own that only you can perform.

02

Pick an action

Screenshot, lock the screen, mute, open an app, run a Shortcut. Pick from the library.

03

Knock to run

Tappy waits quietly in the menu bar. Knock, and it happens. That's it.

Features

Small app. Sharp edges.

Everything Tappy does, and nothing it doesn't.

Three knocks, ready to go

Single, double and triple, each assigned from the library. Want one nobody could stumble into? Record a rhythm — three taps or twenty — and a bump on the desk can't match it.

An action library

Screenshot, lock, mute, Spotlight, switch tabs, open anything, run a Shortcut or a shell command.

100% local

No account, no cloud, nothing uploaded. Only a version check, and you can turn that off.

Knock Feel

Light tap to firm knock. Tune how hard you have to hit so it fires when you mean it — not when you don't.

Context-aware

The same knock can do something else while a chosen app is in front. Triple-knock for Spotlight everywhere, Close Tab in your browser.

Menu-bar native

Lives up top, launches at login, keeps itself up to date, stays out of your way. Feels like macOS.

FAQ

Good questions.

A menu-bar app that feels you knock on your Mac and runs an action — take a screenshot, lock the screen, open an app, run a Shortcut — when it recognises the right one.

Through the motion sensor built into every MacBook — it feels the knock in the case rather than hearing it. No microphone, so nothing is listened to or recorded. On a desktop Mac, which has no such sensor, Tappy counts taps on the trackpad instead.

Only for the actions that press keys for you — Copy, Paste, Screenshot, Spotlight, switching tabs. Those need Accessibility access, and Tappy asks the first time you use one, not at launch. Opening apps, changing volume and the screen effects need nothing.

Your knocks and what they do stay on your Mac — no account, no cloud, nothing uploaded. The one request Tappy makes is a daily check for a new version, which you can switch off in Settings.

Yes. Free download, no account, no license key, no subscription. Just grab the DMG and go.

What's new

Accelerometer detection has landed. Tappy feels the knock through your Mac's case instead of hearing it — faster, far fewer false triggers, and no microphone permission at all.
