Noisy Neighbor

Noisy Neighbor turns your iPhone into a professional noise documentation tool. Whether you're dealing with a loud upstairs neighbor, bass-heavy music, or late-night parties, Noisy Neighbor helps you build a credible, timestamped record to share with landlords, property managers, or local authorities. WHAT YOU CAN DO - Measure real-time sound levels in dB(A) using your phone's microphone - Detect low-frequency vibration and bass rumble through the accelerometer - Log every incident with the exact date, time, duration, and notes - Look up noise ordinances and quiet-hours rules for any U.S. city - Generate professional PDF reports and formal complaint letters - Sign reports with your contact info for a polished, ready-to-send document HOW IT WORKS Create a case for your neighbor or property. Start a recording whenever a disturbance occurs — the app captures average and peak dB levels along with vibration intensity. Add notes describing the noise, then save the incident. When you're ready to escalate, look up your local noise ordinance and export a PDF or complaint letter with one tap. FREE & PRO The free version includes 1 case and up to 10 incident recordings so you can try the app before committing. Upgrade to Noisy Neighbor Pro (one-time purchase, no subscription) to unlock unlimited cases, unlimited recordings, noise ordinance lookup, and PDF/letter export. PRIVACY Audio is processed entirely on-device in real time and never recorded, stored, or transmitted. Your case data stays on your phone. Sound level readings are uncalibrated estimates from the phone microphone and accelerometer. They are suitable for documentation purposes and not certified acoustic measurements.
