## NoiseGauge Description
NoiseGauge uses your iPhone's built-in microphone to estimate ambient sound levels. No external hardware is required. Basic measurements are unlimited, work offline, and include a complete result when you stop.

FEATURES
• Real-time dB reading with a large, readable gauge
• Current, minimum, average, and peak values for the full session
• 30-second rolling waveform chart
• Exposure guidance and a complete result after every check
• Noise reference table with real-world examples
• Manual calibration if you have a trusted reference sound source
• Fully offline — no network, no tracking, no ads

NOISEGAUGE PRO
• Give checks a name and choose a context such as home, work, sleep, or outdoors
• Keep up to 100 records on your device
• Open a record for its statistics and saved trend
• Compare two rooms or time periods side by side
• Use calibration and reference tools

HOW IT WORKS
NoiseGauge reads microphone input, computes the average power in dBFS, then applies a calibration offset to estimate sound pressure level (SPL). The default +100 dB offset works well for most iPhone models. You can fine-tune the offset against a trusted reference meter if closer comparison matters.

IMPORTANT NOTE
Smartphone microphones are not laboratory-grade instruments. NoiseGauge provides estimates suitable for general awareness, not regulatory or medical decisions. For compliance measurements, use a certified Type 1 or Type 2 sound level meter.

PRIVACY
Microphone audio is analyzed in real time and never recorded, stored, or transmitted. No analytics, no ads, no account required.
