Ghost Radar was awarded with "Hottest" award by iPhoneAppsPlus.com 
Android Notes:
The voice synthesizer that the Android version is using is a piece of
third party software. To get Ghost Radar to speak the words you will
need to download the Eyes-Free Project's Text-To-Speech Extensions
from the Android Market. It is free. This requirement will be
removed when the HTC Eris supports Android 2.0.
