About GreenSignal
GreenSignal is a free menu-bar desktop app (macOS & Windows) that runs local pre-call checks so you know you’re ready before joining a meeting. It verifies camera framing, microphone level, background noise (dB), speaker output and network quality (latency) and resolves into a single green READY indicator when everything passes. From the makers of MuteDeck — designed for quick, private checks with a calm, simple UI.
