I love the WordLens App, I found out about it while I was in Santiago, Chile in April 2012 on my way to Easter Island watching a CNN story. WordLens costs $1.99 (additional languages cost extra). I chose Spanish and was able to hold the phone over menus for on screen translation, in front of food labels, signs and tourist attractions. It's super cool technology to help travelers.
