Duolingo is the most popular way to learn languages in the world. Best of all, it's 100% free!
Hey guys Duolingo is great. A couple of suggestions though: 1. Could you add a counter of time spent learning a language. Would love to know that I've spent 3hrs 45 mins until now.
- How many more points are required to go to the next level in the mobile apps.
