We love this new app for iPhones running OS4. It’s called Word Lens and allows realtime translations from Spanish to English and back again.
It uses character recognition (OCR) to define individual letters, identifies the word and translates it in real time. It’s quicker than Google Goggles, because it doesn’t have to query any servers – all of the data is in the ‘phone, meaning you don’t even need to have an Internet connection (which, let’s be honest, could be a pain abroad).
Word Lens is on the App Store, compatible with iPhone 4, 3GS and 4th Generation iPod Touch[youtube=http://www.youtube.com/watch?v=h2OfQdYrHRs]
