Important Note:
This app uses your device microphone, so readings may vary by device model, distance, obstruction, microphone condition, and surrounding environment. Measurements, scene photos, and reports are for everyday reference, record keeping, and communication only. This app does not replace a calibrated professional sound level meter and should not be used as medical, legal, or industrial safety evidence.
