I’ve had Word Lens on my iPhone since the day I saw it on BBC Click. The app is very clever, all you need to do is hover over text and Word Lens reads it and can display it backwards or delete it completely. But there are also some additional packs you can purchase for it; English to Spanish, Spanish to English and more recently French to English and Vice versa. I bought one of these (expensive) packs for going to Spain with, more just to play with. It was very very clever, as said before. Hover over the text, and you can pause the screen so that you can read what it has translated. I found it fantastic for menus and information boards, and
although I did Spanish at school for 2 years it was very useful. Also great to have a play with the free packs.
