Focused on vocabulary?
Yes, it’s because… we honestly believe nobody can learn a new language only with their phone.
You can learn the basics of grammar, you can practice vocabulary but to master another language you have to get out and talk to real people. And it’s even more fun!
That’s why we focus on words, words and words only. Practice that 5-min training every day, and within a few months you can learn enough words to read the news (2000).
