The video says it all, but blogger Judith B. Herman’s says it all when she says your phone can translate signs. Word Lens is an augmented reality app that translates text within the view of a device’s camera. It does so without requiring phone/data reception, too, making it perfect for travelers.
As you can see in the video, the app is fast and the view is clear. And according to PC Mag, it works as shown in the clip except when translating long paragraphs or fast-moving text.
Word Lens is available for free, but translation packs are a premium feature. To see the app for the iPhone or iPod Touch, start here.
