Decent, but very basic
The app is good, and one of the only ones I have seen that uses the Koch method. There are definitely no frills and it is not very intuitive or smooth. There should be pause/play functionality on the built in scratchpad. It takes too long to go back and forth to the main page and hit pause or play. It would also be nice if the scratchpad counted up your mistakes and gave you a percentage - the idea is to move on to the next letter if you get 90% right. It should tell you where you are at.
