## Description

NoiseScope is a personal environmental noise analyzer for
  real-time sound measurement, sleep environment review,
  and long-term noise records.

  Open the app and measurement starts automatically. You
  can check current dB levels, peaks, LAeq trends,
  weighting modes, response modes, low-frequency
  indicators, and noise profile insights in a focused full-
  screen interface.

  Key features:

  - Real-time decibel measurement
  - LAeq, peak, A/C/Z weighting, and Fast/Slow/Impulse
    response
  - Sleep noise analysis with baseline, peak, disturbances,
    and quiet periods
  - Hearing exposure estimates based on NIOSH and OSHA
    references
  - Noise profile insights for low-frequency rumble,
    traffic, mechanical noise, and sudden events
  - Local history with session summaries and event
    timelines
  - PDF reports for single sessions, 24-hour trends, and
    sleep review
  - Microphone profiles, calibration tools, and device
    model adjustment
  - Local-first data storage with no raw recording upload
    by default

  Free features include real-time measurement, basic
  trends, single-session reports, and recent history. Pro
  is a one-time purchase that unlocks advanced reports,
  sleep analysis, full history, calibration tools, alerts,
  and data archive features.

  NoiseScope is designed for personal reference, room
  comparison, sleep environment review, apartment noise
  checks, office noise tracking, and daily sound awareness.
  It is not a replacement for a certified legal sound level
  meter.
