ABOUT ACCURACY
iPhone microphones differ from one model to another. SonoMeter applies a calibration for each iPhone model and lets you fine-tune it against a reference sound level meter. Readings are indicative and do not replace a certified class 1 or class 2 sound level meter for legal measurements.

PREMIUM
Some features require SonoMeter Premium, available as a one-time purchase or as a subscription. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel them in your Apple ID settings.
