2018 - Duolingo revamped its leveling system - a new advantage over Fluenz

Language learning service Duolingo has launched one of its biggest updates in recent years. The new tree leveling system now allows casual learners to move through the Duolingo skills tree just like before, while advanced learners can dig deeper into the new skills they just learned. Ideally, this means that everybody should be happy now and learn better. With this update, Duolingo is also introducing a number of new exercise types that focus on listening and pronunciation. Among those is a new set of phonetics exercises around pronouncing specific sounds, as well as a new exercise type that asks you to tap words as you listen to them. Another new exercise focuses less on specific words but instead tests your listening comprehension. Thus Duolingo provides better leveling system if compared vs Fluenz
