QuietLog

QuietLog is a simple noise logging app that helps you record noisy situations around you.

You can use your device microphone to estimate a reference noise level, save average and maximum dB values, and add your own notes about what happened. QuietLog is useful for keeping a personal record of repeated noise from neighbors, construction, traffic, music, machines, or other everyday sources.

Main features:
- Reference-only dB measurement using the device microphone
- Average dB, maximum dB, and measurement duration
- Automatic date and time logging
- Noise category selection
- Subjective intensity rating
- Personal notes and optional location labels
- Saved noise log history
- Log detail, edit, delete, and filtering
- Statistics by period, time of day, and category
- Local data storage on your device
- Multiple display languages

QuietLog is designed as a local-first personal record app. Your saved logs and notes are stored on your device. The app does not require an account or cloud sync.

Important notice:
The dB values shown in QuietLog are reference-only estimates calculated using the device microphone. Results may vary depending on the device model, microphone performance, case, environment, and device settings.

QuietLog does not replace a certified sound level meter. The values shown in the app are not official or legally valid measurements. For accurate, certified, or official measurements, please use a dedicated professional measurement device or consult a qualified professional.
