Moov is an excellent launcher and all-in-one information retrieval tool for Android. Its most salient feature is its ability to instantly recognize keypad input from the home screen and begin a fast search for almost anything on your G1. You can launch applications, look up contacts, configure global settings, play an mp3, and even bring up websites. All this by simply typing the first few characters of your search from the home screen or from within the Moov app.
The application comes integrated with Google search, Fbook – a Facebook interface, and Quickpedia, Dial Zero (allowing access to a real human behind any major service) and a few other features for quick reference.
