  2. Verified by the community

Not what you see? Report “Ready” as incorrect

This page says version 9.9.9 fills the whole inner screen. If that’s not what Decibel X:dB Sound Level Meter looks like on your iPhone Duo’s inner screen, tell us. It changes to “Not ready” once three people report it, at least one with a screenshot.
