The app is free to download but gets you with the translations. After downloading, you can view a free demo of the app's technology; just point it at any word and Word Lens will automatically reverse all of the letters. To use the translation tool (currently only English to Spanish, or vice versa), you'll have to pony up an additional $5. For those traveling abroad who are worried about sign or menu translations, the app is ideal. And, while there's no timeline for supporting additional languages, the functionality is sure to follow.
Check out the blow-your-mind demo video after the break.
