## What is dB Decibel?

dB Decibel is an iPhone sound level meter that measures ambient noise in real time in dB(A) with peak hold, and flags when a sound falls below the microphone floor or clips the mic so you can trust every reading. Everything runs 100% on your device with no subscription and no tracking, and audio is never recorded or sent.

Most meters read 50–60 dB in dead silence and cap loud sources. dB Decibel is honest: it tells you when you are below the mic floor and when a sound clips the mic, so you trust every reading.

One fair price. No subscription, no tracking. Everything runs 100% on your device. Audio is never recorded or sent.
