## Description

Turn your iPhone into a sound level meter. Measure ambient noise in decibels with min/max/avg tracking, real-time charts and CSV export. No ads, ever.

Decibel Meter turns your iPhone into a fast, accurate sound level meter. 
Measure ambient noise in decibels (dB) anytime, anywhere — at home, at 
work, at concerts, in cafes, or in the gym. Clean design, instant results, 
no clutter, no ads.

WHAT YOU CAN DO

• Live Decibel Reading
  Watch sound levels update in real time, with a colorful indicator that 
  shifts from green (quiet) through yellow (moderate) to red (loud).

• Min, Max & Average
  Track the quietest moment, the loudest peak, and the average noise 
  level of every session.

• Real-time Sound Chart (Premium)
  See your environment's noise pattern visualized as a smooth live chart.

• Measurement History (Premium)
  Save up to 50 sessions with date, min, max, average and duration. 
  Compare locations, times of day or before/after changes.

• CSV Export (Premium)
  Export your full history as a CSV file. Share it via email, AirDrop or 
  any app — perfect for reports, schoolwork or simple personal tracking.

• Manual Calibration (Premium)
  Fine-tune readings against a reference device with a ±20 dB offset 
  slider that fits your hardware.

WHY DECIBEL METER

• Privacy first — all measurements stay on your device. No accounts, no 
  cloud, no tracking.
• 100% offline — works without an internet connection.
• Zero ads — we don't show ads in any of our apps. Ever.
• Beautifully simple — built natively for iOS with a clean, minimal 
  interface.

GREAT FOR

• Checking how loud your office, classroom or living room really is
• Measuring noise levels at concerts, restaurants, gyms or events
• Comparing the quietness of different sleeping spots
• Curious kids, students and tinkerers learning about sound
• Anyone who's ever wondered "how many decibels is this?"

PREMIUM

Unlock advanced features with a one-time premium upgrade — no 
subscriptions to forget about. Premium adds the real-time chart, 
measurement history, CSV export and manual calibration.

IMPORTANT

This app is intended for entertainment and informational use only. It 
relies on your device's built-in microphone, which is not a calibrated 
laboratory instrument. Do not use Decibel Meter as a substitute for a 
professional sound level meter, occupational safety equipment, or any 
medical or legal measurement.
