Morse Coach app is designed to help you learn and master your skill at morse code at various speeds.
Morse Coach uses the well known Koch method for learning morse code. The process involves starting with your desired end speed, instead of ramping up with training. By beginning at your desired speed you are training your ear to read at that speed from the outset.
You begin with two characters, and transcribe randomly generated patterns. When your accuracy gets above 80%, you move on to the next level adding another character.
