Your light knows when you're on a call. Busyflag turns a Luxafor Flag red while any app is using your microphone or camera, amber while your screen is locked, and green when you're free. It watches the operating system, not your meeting app, so it works with Teams, Zoom, Meet, Chrome, Slack and everything else, with no setup.
- macOS, Windows and Linux (including Raspberry Pi), one small app each
- No accounts, no network, no telemetry; never needs microphone or camera permission
- Force busy for a while, pause, camera as busy, hold time, custom colours
- Activity log of what used your mic or camera and for how long, as a CSV you own
- Starts at login, survives unplugging, colour-blind-friendly tray glyphs
- Fleet-ready: silent installers and an admin defaults file
