When you’re traveling in a foreign country, reading signs and printed material can be tough, even if you have a basic understanding of the language. That’s why I love the Word Lens app. You just launch the app on your iOS or Android device, look at the foreign text through the viewfinder, and presto! The words change into a language you can read right before your eyes.

It’s five bucks for every language pack — well worth it.

It’s awesome (and fun) to watch!
