Decibel Meter Pro ★★★★☆ ($.99 / App Store) for the iPhone and iPad is an app that measures decibels. The great thing about iOS apps is that there are a lot of things apps can do that are very specific and do it very well, and nothing else. Decibel Meter Pro is one of those applications. Even though it is considered an Entertainment App, the result of decibel measurements are surprising accurate - using the iPhone or iPad’s built in mics. The user interface is quite fantastic and looks even better than the real thing.
