Decibel Meter - Live sound level and daily noise dose on iPhone

A live dB number does not tell you when a room is costing you hearing. Decibel Meter shows real-time sound level plus your daily noise dose against the NIOSH 85 dB / 8-hour standard. Audio is analyzed on your iPhone and never recorded or uploaded. No account, no ads, no tracking. Free core: live dBA, NIOSH/OSHA dose, Home Screen widget, Apple Watch. Optional Pro is a one-time buyout for spectrum, export, and calibration.
