Hey Product Hunt 👋 I kept fumbling the start of calls when my setup changed, so I built GreenSignal: a calm, free pre-call check that lives in your menu bar. Camera, mic, room noise, speaker, network, one glance, one truth. It runs entirely on your computer, nothing is recorded or uploaded. Would love your feedback!
