Store description excerpt

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.
