Sound Meter & Decibel Meter

See how loud it is around you, right now, in one big number. • Big, easy-to-read decibel (dB) reading that updates live • What it's about as loud as: a whisper, a conversation, a lawn mower, a rock concert • Level bar plus a graph of the last minute in green, yellow and red • Min, Avg and Max since you started, with Pause and Reset • Calibration, to match a real sound level meter if you have one • Keeps your screen on while you measure Private by design: sound is measured live on your phone, a fraction of a second at a time, and never recorded, saved or sent anywhere. No account, no sign-up. Check a noisy shop or job site, a loud neighbor, a concert, a classroom, a baby's room, your car or your music. Readings are approximate. Phone microphones differ, and a phone isn't a certified sound level meter. Free, with one small ad at the bottom.

First release: live sound level in decibels, a level bar, a one-minute graph, Min, Avg and Max, and calibration.
