## Description

Noise Diary & dB Meter helps you understand and document everyday sound levels. Measure ambient noise, add context and notes, and build a searchable history of readings. Review trends, compare saved measurements, and export your data when you need a personal record. The free version includes core measurement and history tools. Lifetime Premium removes ads and unlocks longer sessions, expanded history, comparison, calibration, and export features with a one-time purchase. Sound measurements are estimates based on your device microphone and are not a substitute for calibrated professional equipment or safety advice. The app measures sound level only and does not record, store, or transmit raw audio.
