I downloaded and played with Word Lens briefly last year. There was only a text-reversing demo for free, the translation required in-app-purchases.
But I see that Google just bought the company and made the app and in-app-purchases free. This thing is amazing. You point the camera at some text: a magazine, wall sign, paper, whatever. And it translates it right there in place. You have to see it to believe it.
If you have an iPhone download the app Word Lens, then go in and download some of the language translation modules inside the app. Then give it a try. You have to see it to believe it. My son would mow lawns for the entire summer if they had a module that translated to and from Latin.
Imagine going back in time just twenty years and being able to show this to someone. And say 50 years?
The amazing Word Lens app for iOS is now free: “Imagine an iPhone app that can instantly translate written text between languages in real time. It sounds like science fiction, but Word Lens (free) does exactly that. We were wowed by the app back in 2010 and now its parent company, Quest Visual, has been purchased by Google. The immediate result is that World Lens is now free. Additionally, Language packs that were formerly available via in-app purchase are now free as well.”
