iOS: Google Googles is a great way to search for objects in the real world based on an image, but it's not exactly the most accurate app out there. CamFind does the same basic trick, but it's more accurate and provides a wealth of information.
Like Google Goggles, you just need to snap a picture of something in CamFind, and it hunts down the image to give you information. This can be text, landmarks, products, books, art, translations, and even movie posters. Once you snap a picture, CamFind searches for similar images and then provides you with shopping information, related places, Yelp results and more.
Compared side-by-side, CamFind seems a bit more accurate then Google Goggles, albeit a little slower on the search itself. If you tried out Google Goggles and were underwhelmed by the results, CamFind is worth a look.
