Just a friendly heads up, for the Japanese exercises the video starts just a bit too late and the word you're listening for is cut off. This might only be pertinent for languages where vocab words are appearing at the beginning of sentences, French and Spanish didn't have "gap words" at their sentence start for the few exercises I tried.
This is a cool app, I would have enjoyed this when I was grinding on Japanese back in the day.
