Measure environmental noise, save recordings, and keep incident details together. With Pro, create PDF reports, export CSV data, and prepare complaint letters for you to review and share.
Available on Google Play. The iOS version is being prepared and is not yet available on the App Store. Recording limits differ by platform; see the FAQ.
Charts and report illustrations on this page use sample data; they are not app screenshots.
Organize what happened, then decide what to share. Measurements are estimates and templates are guidance.
Start the meter and choose manual audio recording or threshold-based saving. On iOS, keep the app open: capture stops when you switch apps or lock the screen. On supported Android versions, a microphone foreground service can continue an explicitly started session with a recording notification.
With Pro, turn your saved measurements and incident details into a PDF report. Review the content before sharing. Reports are personal documentation, not certified acoustic assessments.
Choose an available template, check the facts, recipient and local requirements, then share using your chosen app. Noise Log does not file or send complaints automatically.
Recording behavior depends on your platform. iOS capture stops in the background; supported Android versions use a visible microphone-service notification. Interruptions can end a session.
Follow estimated sound levels with a live visual indicator. Results vary with your microphone, placement and calibration.
Choose a threshold for automatic audio saving during an active measurement. On iOS, automatic saving is off by default and requires a separate confirmation.
Save audio when you choose Record or enable automatic saving. Sessions without audio remain useful as measurement logs.
Optionally add location and a resolved address when permission is granted. You can record without location access and enter an address yourself; address lookup can use network services.
Bring the dates, measurements and notes together in a readable report. How a recipient assesses your documentation depends on their requirements.
Organizes saved measurements, timestamps and incident details, with a measurement disclaimer. Optional location appears only when available.
Use your incident details to prepare a template letter. Review every field and check current local rules before sharing.
Export measurement data as CSV with Pro for your own records or review by someone you choose.
Open the system share sheet and choose a compatible app or destination. Your chosen provider handles any transfer.
Examples of available template jurisdictions. Check current rules and the correct recipient for your address; templates are not legal advice.

Start with a clear record of the noise you experience. Measure, save the details, and review before you share.
