Five Reasons to Download the Free Duolingo Software The latest version of the Duolingo app features a completely revamped interface, making learning a new language a breeze. All new features, except the Practice Hub, will be available to free users and Plus subscribers alike. The app is now rolling out to iOS users and Android users will soon follow. It's easy to see why people love this app so much. Here are five reasons to give it a try: First, leveling up. As you learn new vocabulary, you'll move up the levels. This process is called "leveling" and takes XP. You'll need to earn XP in each language that you study. There are 25 levels total. You can choose to work toward the highest level in each language or go level by level. While overall XP on the app isn't that important, you'll need XP in specific languages to advance. There are 41 languages available on Duolingo. Most of them are aimed at English speakers. Support for languages varies depending on their popularity. Duolingo offers courses in 22 languages, including English. Spanish speakers can choose from Guarani and Catalan. And for other languages, there's French, German, and Spanish. As with any other educational service, you should always check back frequently and see what's new. The interface is designed to make language learning as fun and rewarding as possible. It has sleek, bright colors and a mascot that looks like an owl in neon green. Moreover, the progress bar looks like an RPG's experience bar, encouraging you to keep pushing and unlock new paths. But what's the main attraction of Duolingo? Its simplicity is unrivaled by other language learning apps.
