## Description

Measure ambient sound in real time, record detailed sessions, mix 16 calming soundscapes, and run privacy-friendly device checks—all in one app.

Understand the sound around you with a clear, real-time decibel meter.

Decibel Meter turns your iPhone or iPad into a practical sound-level companion. View the current reading, minimum, average, maximum, range, live trend, and noise category at a glance.

MEASURE AND UNDERSTAND SOUND
• Monitor ambient sound levels in real time
• See current, minimum, average, maximum, and range values
• Follow an 18-second live analyzer and session duration
• Compare readings with a built-in noise level guide
• Calibrate from -20 to +20 dB against a trusted reference

RECORD YOUR MEASUREMENTS

• Review saved sessions whenever you need them
• Delete saved measurements easily
• Keep measurement data stored locally on your device

RELAX, FOCUS, OR SLEEP

• Adjust each sound independently
• Save favorite mixes as presets
• Set a sleep timer and receive a local notification when playback ends
• Continue soundscape playback in the background

CHECK YOUR DEVICE
• Test the microphone and speaker
• Review battery, storage, display, connectivity, audio routes, and available sensors

PRIVATE BY DESIGN
Microphone audio is analyzed on your device. The app does not upload your listening session. Recording a measurement saves sound-level data and statistics—not microphone audio.

IMPORTANT
Phone microphones are not certified sound-level meters, and readings may vary by device. Calibrate against a trusted instrument when accuracy matters. This app is intended as a practical reference tool and is not a substitute for certified equipment or professional hearing-safety advice.

PREMIUM FEATURES — SEPARATE PURCHASE REQUIRED
• Unlimited measurement recording requires a Premium subscription
• Removing advertisements requires a Premium subscription
