ZeroHz provides scientifically-backed soundscapes including rain, flowing water, and wind that create an optimal environment for deep work.

ZeroHz is designed as a menu bar app that lives quietly in your system tray. It doesn't appear in the Dock intentionally — this keeps your workspace clean and distraction-free while staying accessible with a single click.

Click the ZeroHz icon in your menu bar, then select 'Activate License' from the dropdown menu. Enter your license key in the dialog and you're all set.

Yes! You can show or hide the ZeroHz window instantly with a global keyboard shortcut. You can also customize this shortcut in the Settings menu to fit your workflow.

Ambient sounds work 100% offline — perfect for flights, coffee shops with bad WiFi, or focused sessions without internet. The lofi music channels require an active internet connection to stream.

Yes! You can select multiple soundscapes simultaneously, adjust each volume independently, and save your favorite combinations as presets for quick access. For example, combine rain + fire + wind for a cozy cabin atmosphere.
