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.
