Simple Sound Meter

Turn your iPhone into a simple ambient sound indicator. The screen shifts from green to red as noise increases—with optional warning sounds and customizable thresholds.

Simple Sound Meter is a fast, visual way to monitor ambient noise. It listens to the microphone and fills your screen with a color that reflects your current sound level—green for quiet, yellow for moderate, and red for loud.

Features

• Full-screen color indicator (green → yellow → red)

Privacy Audio is processed on-device for live feedback. This app does not store recordings and does not collect personal data.
