## Description

Measure the sound levels around you in real time.

Decibel Meter turns your iPhone into a sound level meter. Point your device at any sound source and get instant dB SPL readings displayed on a clear circular gauge with a live-updating chart.

REAL-TIME MEASUREMENT
See your current sound level update 10 times per second. The circular gauge changes color to indicate safe, moderate, and dangerous noise levels at a glance.

LIVE CHART
Track how sound levels change over time with a continuously updating line chart. Free users get a 15-second window; Pro users can extend it to 30 seconds, 1 minute, 2 minutes, or 5 minutes.

SESSION HISTORY
Save your measurement sessions and review them later. Each saved session includes average, minimum, maximum, and peak dB levels along with a visual sparkline of the recorded data.

PRO FEATURES
Upgrade to unlock the full experience:
- Detailed statistics (Min, Avg, Max, Peak)
- Extended chart durations up to 5 minutes
- Full session history
- Microphone calibration offset

PRIVACY FIRST
All audio is processed entirely on-device. Nothing is recorded, stored, or sent anywhere. Period.

IMPORTANT
Decibel Meter provides estimates based on your device's built-in microphone. It is not a calibrated measurement instrument and should not be used for regulatory, occupational health, or safety compliance purposes.
