About this app

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.

What’s new

Initial release. Measure sound levels, save noise diary sessions, compare records, and review trends. Measurements are reference values and do not replace professional equipment or medical or legal judgment.
