## What is NoiseProof?

NoiseProof turns your phone into a noise evidence recorder — not just a decibel meter.

■ Real-time dB meter
See current, min, average and peak sound levels with a live waveform. Calibrate to match a reference meter.

■ Threshold auto-recording
Set a level (e.g. 60 dB). When noise stays above it, NoiseProof records automatically — and saves the 2 seconds before the noise too. It stops when things quiet down.

■ Timestamped log
Every event is logged with date, time, peak dB and duration. Night-time events (10 PM–6 AM) are highlighted — exactly what matters for noise complaints.

■ Scheduled recording
Set it to watch a specific time window, like overnight.

■ PDF report
Export a clean report — total events, night-time count, peak level and a full table — to share with your building manager or neighbors.

■ 100% private
Recordings never leave your device. No account, no upload, no cloud.

Note: phone-mic readings are relative reference values; certified measurement is required for legal disputes.
