It's very cool, except for 2 things:
This morse code keyboard is really cool, and really helps you practice morse code more! The single button mode is quite accurate, and it is also cool to show your friends. I only have two complaints: 1. You cannot control the delay between finishing tapping a letter and it typing the letter out. 2. The sound of the dits and dahs are not synced with the button presses when you are using the single button mode (the one I use to practice morse code), so I have to turn the sound off. But this app is still solid, you should try it.
