## What is SoundGauge?

SoundGauge turns your iPhone into a real-time dB(A) sound level meter that also tells you how long that noise is safe to listen to. Point it at any room — a concert, a workshop, a busy office — and see the live reading, a plain-English context label, and your running average and peak.

Most decibel apps stop at the number. SoundGauge adds the part that matters for your ears: a safe-listening countdown based on the NIOSH 85 dB / 8-hour recommended exposure limit, so a quick glance tells you whether you're fine for hours or should step out soon.

— WHAT MAKES SOUNDGAUGE DIFFERENT —
• Safe-listening countdown, not just a number
  The reading comes with how long that level is safe to listen to, based on the NIOSH 85 dB / 8-hour recommended exposure limit.
• Plain-English context labels
  Quiet room, city traffic, live concert — you always know what the number means without memorizing decibel scales.
• Running average (LEQ) and peak
  A fluctuating needle is hard to trust; the session average and peak give you the honest picture of the whole exposure.
• Exposure sessions with daily noise dose
  Log a timed session and see its average, peak, duration, and what percent of your safe daily noise dose it used.
• Full exposure history
  Every logged session is kept on a timeline you can review anytime.
• CSV export
  Send your log out as CSV — for your own records or for your audiologist.
• Calibration and two-week dose trends
  Pro users can fine-tune the meter to their microphone and review their daily dose at a glance.
• Private by design
  Everything runs on-device. No account, no ads, and audio is never recorded or sent anywhere.

— PRICING —
Included with the app: live dB(A) meter, safe-listening time, running average (LEQ) and peak, and plain-English context labels.
SoundGauge Pro is a one-time in-app purchase — not a subscription — and unlocks timed exposure sessions with daily-dose percentages, two-week dose trends, microphone calibration, full exposure history, and CSV export.

— FEEDBACK —

SoundGauge gives a helpful estimate from your phone's microphone for everyday awareness. It is not a calibrated instrument and is not a substitute for professional hearing assessment or occupational noise monitoring.
