SoundLevel: Noise Estimate
See and log approximate sound estimates with minimum, energy average, maximum, history, in-app threshold alerts while you measure, and exports with clear limitations.
Download on theApp StoreSoundLevel uses microphone amplitude to provide an approximate uncalibrated sound-level estimate in dB. Log sessions and compare how your estimates change across places and time.
SoundLevel is not A-weighted, calibrated, or a certified measurement instrument. Values can vary by device, case, placement, and environment. Do not use the app for safety, occupational compliance, medical, or legal decisions.

- No guideline time or percentage calculated below 85 dB
- Six-week summaries, week-over-week comparison, and highest logged estimates
- A reference offset that shifts the displayed estimate but does not calibrate the device

- Local storage with no account, cloud sync, analytics, or tracking
