## What is NoiseLog?

NoiseLog turns your phone into a fast, accurate sound level meter. Point it anywhere and read the decibels in real time — then log, chart, and understand the noise around you.

MEASURE
• Live dB gauge with a smooth, readable needle
• Min, average, max and peak for every session
• Calibrate to match a reference for better accuracy

LOG & ANALYZE
• Save measurements with one tap (or auto-save on stop)
• Professional time-based charts — min, avg, max, peak
• Export any measurement to CSV and share

STAY SAFE
• Loud-noise alerts with a custom threshold
• NIOSH safe-exposure guidance at a glance
• A clear reference for what every decibel level means

PRIVATE BY DESIGN
Audio is analyzed on-device in real time. It is never recorded, stored, or sent anywhere.

ONE-TIME PRO — NO SUBSCRIPTION
Unlock unlimited history, alerts, detailed charts, and CSV export with a single purchase. Pay once, own it forever.

Note: a phone microphone is not a certified sound meter. Readings are estimates — use them as a guide, not for compliance.
