## Description

SoundLevel Pro turns your phone into a real-time decibel (dB) sound level meter. Point it at whatever you want to measure and watch the loudness around you on a big, color-coded gauge.

MEASURE IN REAL TIME
• Large analog-style meter with a live dB number
• Color zones at a glance: green (quiet), amber (moderate), orange (loud), red (dangerous)
• Peak, average and minimum readings
• Live scrolling chart of recent readings

NOISE ALERT
• Set a threshold (e.g. 85 dB) and get a visual + haptic warning when it is exceeded
• Great for a baby's bedroom, an office, a workshop or your neighborhood

HISTORY
• Stop a measurement to save its summary (peak / average / min and duration)
• Browse and manage past sessions anytime

dB REFERENCE GUIDE
• A handy table of everyday sound levels — whisper, conversation, traffic, concert and more

MADE FOR EVERYONE
• Light & dark themes with multiple accent colors
• English and Japanese
• Calibration offset to match a reference meter
• Keep the screen on while measuring

PRIVACY FIRST
• Works fully offline. The microphone is used only to measure loudness — audio is never recorded, saved or sent anywhere. No account, no cloud, no tracking.

Note: readings are approximate and depend on your device's microphone. SoundLevel Pro is intended for general awareness, not for professional or regulatory measurements.

Free, supported by ads.
