Koch Trainer is a morse code trainer that uses the Koch Method developed by the German psychologist Ludwig Koch in the 1930's. The method basically states that you should learn morse code at the speed you expect to receive, by training your reflexes to respond to code sent at 20 WPM you'll learn the code much faster.
