This app is definitely one of the best ever to come out on the App Market! Voted Google Play’s ‘Best of the Best’ in 2013, this app helps you learn Spanish, French, German, Portuguese, Italian, and English. The operative word: FREE! Even the WSJ is sedately appreciative of the quality put into the app’s content. Here, you lose ‘hearts’ for answering incorrectly, advance by completing bite-sized lessons, and track your progress with shiny achievements. And for India-specific focus - an English course for Hindi speakers! How extremely cool is that?
