Features:
- dB(A) and dB(C), Fast and Slow
- Min, average and max values
- Level, waveform, spectrum and frequency graphs
- Everyday noise reference
- Calibration with a sound calibrator or by hand
- Works offline, no account, never records audio
dB Now Pro (one-time purchase):
- Noise log with chart
- CSV export

Our ads never make sound. It's a sound meter.
Note: Phone microphones are made for voices, so very loud sounds may go past what they can measure. Uncalibrated readings are typically within ±3 dB. The noise log runs while dB Now is open. For reference only, not a certified sound level meter.
