Duolingo’s iPhone app update includes a language coach, in-game currency

Language-learning app Duolingo has released an entirely new version of its app, which introduces more gamified features to keep users engaged. In addition to its existing lessons, the company unveiled a feature called “The Language Coach” — essentially a software taskmaster (mascot Duo the Owl) to keep users on track for goals. There is also a new in-game currency, called Lingots, that offer “power-ups” to users while they learn. The feature leans heavily on existing freemium methodology, but they aren’t necessary to complete lessons. All in all, the app’s gamification is a clear move to keep users coming back for more.
