This app is BY FAR the best way to learn vocabulary. Clean design, no ads, and the most important feature is that the algorithm just works like a charm! Out of a 30-min training session, 25 mins will be productive time spent actually learning. Also, you get to learn the most important words you need to get a working knowledge of the language. In other apps like Anki, you end up spending far too much time with settings, etc.

This application builds your vocabulary like none of the other apps or books. Have been using it for about 3 years to study French. I don’t practice French too regularly, but with the help of this app and its algorithms, I can still remember 90% percent of words I’ve learned here. Great respect to the creator of this app!

I wanted to expand my German vocabulary and stumbled across this app. The spaced repetition is brilliant; the app knows exactly which flashcard to show me at the right time to help me learn quickly. 10/10.
