Turn your iPhone into a professional noise evidence tool. Log noise events, track patterns, and generate PDF reports for landlords, courts, or property managers. Dealing with noisy neighbors? Need proof for your landlord or a noise complaint? dB Guard turns your iPhone into a calibrated noise meter and evidence logger — the only tool you need to document noise problems and build a professional case. REAL-TIME NOISE MEASUREMENT Measure decibel levels in real time with a clean, easy-to-read gauge. Set your own dB threshold and dB Guard will automatically detect and log noise events when sound levels exceed your limit. AUTOMATIC NOISE EVENT LOGGING Every noise event is captured with precise timestamps, peak dB, average dB, and duration. Add notes and photos to document the source. Events are grouped by date so you can see your full noise history at a glance. QUIET HOURS RULES Set up quiet hours rules (e.g., 10 PM – 7 AM) with custom dB thresholds. dB Guard automatically flags violations, giving you clear evidence of noise during protected hours. NOISE PATTERN ANALYTICS (PRO) See when noise is worst with a weekly heatmap showing patterns by day and hour. Track your noisiest hours, quietest days, total events, and average peak levels over 7 or 30 days. PROFESSIONAL PDF EVIDENCE REPORTS (PRO) Generate timestamped PDF reports with noise statistics ready to share with landlords, property managers, HOAs, or courts. Present professional, objective data instead of verbal complaints. ALL DATA STAYS ON YOUR DEVICE Your noise data is stored locally on your iPhone. We don't collect, transmit, or sell your data. Your evidence is yours alone.
