mactooloud is a macOS app that turns the system volume into a per-app mixer. Each running app gets its own slider, with Auto-Duck on calls, Whisper Mode for late-night listening, Pomodoro / Focus Audio, and per-app output routing. Saved profiles let you switch between Work, Gaming, and Movie mixes in one click. Built locally on-device — no audio ever leaves your Mac. Made by ByteLights.

Long — full description (~160 words)

mactooloud is the per-app volume mixer macOS forgot to ship. It taps each running app's audio output and gives it an independent slider, so you can boost one app, mute another, and route a third to a different output device — all from your menu bar. Beyond the mixer, it includes Auto-Duck (drops music when a call starts), Whisper Mode (compresses dynamic range for late-night listening), Pomodoro / Focus Audio (timed sessions with ambient sound), saved audio profiles, and the Mystery Sound Finder (locates which background app is making noise). All processing happens on-device — audio never leaves the Mac. mactooloud runs on macOS 14.4 or later, Universal binary for Apple Silicon and Intel. It's free to try for 7 days, then $4.99/month or $39/year. Built by ByteLights.
