QuietTrace: Sound Journal

QuietTrace is a private sound journal for moments you want to remember without recording audio. Turn listening on once and it keeps listening — visibly, and entirely on your device. Sounds are identified on device, and only classifications and times are saved, never audio recordings. Always-on listening, live identification, the complete local journal and the Apple Watch companion are free. One optional lifetime purchase unlocks archive search, filtering, CSV export and iCloud sync between your own devices, with no subscription and no account. QuietTrace is not a calibrated decibel meter, safety tool or audio recorder.
