Echoroom is a one-tap room reverb meter for podcasts, calls, music rooms, and everyday acoustic checks. Tap Measure and Echoroom plays a short impulse, listens for the decay, estimates RT60, and gives a plain-language verdict for voice, music, or echo control. Audio is processed on device. Echoroom stores measurements and decay curves, not recordings, and has no account, ads, tracking, analytics, or subscription.
