Sits in your menu bar
A little duck lives quietly at the top of your screen, next to the Wi-Fi icon. It behaves. Right up until you start typing.
a macOS menu bar app
A duck for your keyboard.
Kwack is a tiny macOS menu bar app with exactly one feature: it plays a quack sound every time you press a key. Any key. Every time.

What it does
Hears every key
Kwack asks for macOS accessibility permission so it can hear keystrokes in any app — then uses that power for exactly one thing: quacking. Nothing is recorded, stored, or sent anywhere; Kwack never touches the network.
Duck, duck, mute.
The entire settings surface is one menu item: Enable Quacks / Disable Quacks. When the meeting starts, you know what to do.
The honest bit
Kwack does exactly one thing. There are no themes, no sound packs, no stats, no subscription — just one very good quack, on every key, until you tell it to stop. It's free on the Mac App Store.
It's a duck.
