Word Lens, by Quest Visual, is an app which instantly translates printed words from one language to another using the video camera on your iPhone. The most amazing part is that it does this real time. It also imitates the scene you are recording, making it very user friendly. It’s still in it’s early stages, as it can only translate English to Spanish or vice versa, but it is available for free in the iTunes store. A great application to have if you are traveling internationally! Requires iPhone 3GS or higher.
“Word Lens is a dictionary — evolved. It looks up words for you, and shows them in context. You can use Word Lens on your vacations to translate restaurant menus, street signs, and other things that have clearly printed words… No network delay, no roaming fees, and no reception problems” – Word Lens
