DuoLingo started life in 2011 and has since grown into a language-learning platform used by millions. It is ad-free and completely free for users to access, making it a fantastic resource that can be placed in your pocket thanks to its app-based structure. The success of the app lies in the gamification it implements. By offering tiered rewards and achievements, the app incentivizes you to learn languages without ever feeling like a chore. You can score points, lose lives and end up on a virtual scoreboard, all elements taken from gaming and expertly translated to the app. Lessons are provided in blocks that echo the talent system in titles like World Of Warcraft, where new tiers are unlocked as you progress down the tree. It also presents streak awards and spoken translations. So far, the app has 14 languages available. If you love gaming and you fancy learning a new language, the door has never been easier to open.
