Finally, I've been waiting for this: with a post on the official company blog Google has just announced that the Google Mobile iPhone app has been updated to include support for Google Goggles, the free service that allows you to search by taking pictures. An iPhone version of the popular Android-only service was first announced in June.
The app isn't available yet in the US Store (I guess it's still propagating). Check out the video below.
Update: the app is now live in the App Store. Update #2: I took a quick test, the app works great. Check out my screenshots below.
In the new version of Google Mobile App just tap on the camera button to search using Goggles. Goggles will analyze the image and highlight the objects it recognizes -- just click on them to find out more.
Goggles is enabled only for English-speaking users, and since it requires an auto-focusing camera it is supported only on iPhone 3GS and iPhone 4 running iOS 4 or above.
I'm blown away by the accuracy of this app, by how fast it is at fetching results and presenting them to you. I took some crappy pictures of stuff in my room with low light, and the app managed to get results in seconds. Great.
