Decibel Meter - Precision Tool turns your Apple Watch into a professional-grade sound level monitor. Get real-time decibel readings with a beautifully designed gauge interface, right on your wrist.

REAL-TIME SOUND MONITORING Measure ambient noise levels instantly with a responsive, high-refresh metering engine. The precision gauge updates 20 times per second, giving you accurate readings from whisper-quiet rooms to loud concert venues.

PROFESSIONAL GAUGE DISPLAY A sleek speedometer-style arc visualizes sound intensity from 0 to 120 dB. The dynamic needle moves smoothly with spring physics, making it easy to read levels at a glance.

SMART COLOR INDICATORS Instantly understand your sound environment: Green: Safe levels below 75 dB Yellow: Moderate exposure between 75-90 dB Red: Dangerous levels above 90 dB
