LEVELS

A per-app volume mixer for macOS. Turn one app down without touching the rest.

Shipped and available at uselevels.app.

OVERVIEW

Levels gives every running app its own volume slider. Pull a loud browser tab down while music stays put. The mix macOS never gave you.

A finished, notarized, shipping product, not a prototype.

THE BUILD

Native Swift + SwiftUI on top of Core Audio taps. Notarized DMG, licensing, the full go-to-market.

WHAT'S NOVEL

Real per-application gain on macOS without routing through a virtual audio device.
