Decibel Meter ·dB Sound Levels

Check sound levels with Decibel. Decibel Pro is required to use the meter and tools, including on existing installations. No account is required. MEASURE AND RECORD WITH PRO • Start and stop the meter yourself and follow the live level on a clear gauge. • Review duration, average, minimum and maximum after stopping. • Adjust the calibration offset against a reference sound level meter. • Save measurements with names, notes and tags; sort, filter and search your history. • Compare two saved measurements and export individual PDF or CSV reports. • Share results as image cards and create photos or videos with a dB overlay. • Track levels over time with Noise log and save reports with Pro. PRO ACCESS AND PURCHASES Choose an auto-renewing weekly, monthly or annual subscription. Available plans, localized App Store prices, billing periods and terms are shown before checkout. Subscriptions renew automatically unless cancelled in your Apple account subscription settings. Cancelling renewal keeps access through the paid period. Existing valid Lifetime purchases keep their permanent access. Restore Purchases on the entry screen to recover existing valid purchases. Existing purchased rights are preserved. Without Pro, you can still open and delete previously saved records and play saved recordings through the saved-records screen. Creating new measurements, recordings and tool sessions requires Pro. Phone readings are estimates, not certified measurements. The default meter shows unweighted estimates from the phone microphone, not dB(A). Saved meter measurements contain sound levels, not audio. Calibration needs a reference meter and does not make the phone a certified instrument. Hearing checks are not a medical diagnosis.
