QuietLog helps you record noise the moment it becomes a problem. Start a session, set your dBA threshold, and let QuietLog track sound levels, mark over-limit events, and save clean audio clips for review. Use QuietLog for: • Neighbor noise and apartment noise • Late-night loud sounds • Home, office, dorm, hotel, and shared spaces • Keeping a clear noise log with time, peak dBA, duration, and audio What QuietLog does: • Measures live sound level in dBA • Marks events when noise crosses your threshold • Saves raw session audio and event clips • Builds a clean report you can review and share • Continues recording during an active session when you leave the app • Shows every recorded event in the report timeline QuietLog is built for stressful moments. Open it, start recording, and get a simple report instead of trying to explain what happened from memory. Note: QuietLog is designed for personal noise logging. Phone microphones are not professional calibrated sound meters, so readings may vary by device and environment.
