Google Goggles is now available for download in the iTunes App Store, but you have to have the right device. The only two devices with hardware good enough to be accepted by Google are the iPhone 4 and iPhone 3GS. Why not iPod touch 4, iPhone 3G, and below you ask? Simple; the app requires an auto-focus camera.
Google Goggles is one of those features Android, Google’s very own smartphone OS, (previously) could claim exclusivity to. The app takes a photo of an object, and scans a vast internet database to find images that are similar. It then figures out what those images are labeled as, and then gives you as much relevant information as it can. For example, a picture of the Eiffel Tower in Paris, France would be examined, searched, and then you would get background information, such as history, statistics and facts, and location.
All things considered, this is a very interesting move by Google, as the search juggernaut has advertised this app and its capabilities as being specific to Android in the past.

Google Goggles is available in the iTunes App Store for free, and is compatible with the iPhone 3GS and iPhone 4.
Edit: To clear up some confusion, Google Goggles is available as an update to the Google Mobile app (link below). If you already have it, update the app via the App Store. If you don’t, download it via the link below.
