What is AppVolume?
AppVolume is a clean, fast, and low-latency audio mixer for macOS that lets you control the volume of each app individually.
No subscriptions. No clutter. Just intuitive, per-app sound control right from your menu bar.
Balance background music with calls, quiet noisy browser tabs, or fine-tune your workspace sound — all from one simple place.
Status: 🚧 In active development — very early stages.
