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.

Great compared to competition

This is a SUPER basic app. The user interface isn’t really what someone that ever USED it would have built. BUT it is one of the only apps in the entire store that isn’t a child’s toy. This is a genuine learning app. The most glaring omission is that it doesn’t grade your session, it will display - In A Different FONT - what it sent and what you typed. If this sounds hard to reconcile, it is!

This app seems like a beta release from someone that doesn’t really know what the app should do or how it should work. Still that does’t change the fact it is one of the VERY BEST in the entire store.

Nice app

A good solid app for learning or practicing CW.

As the previous review said there are a few tweaks that would make it even better.

The scratch pad is worlds with the standard iOS keyboard. You do not have time to toggle the keyboard for numbers and punctuation. All standard CW letters, punctuation, should be on one keyboard.


A great tool to learn CW!

This is a basic app to learn CW, no frills. I’ve been using this app daily for several months and so far I find it to be the best resource for learning CW.

You have the option of changing WPM, or the space between the sent letters. You can adjust the pitch of the tone as well as how many characters will be sent in a test session. You can choose the Koch method where only a few characters are added at a time. You can practice call signs, words or even qso’s.

My only complaint is that I can’t pick specific letters or characters to practice.

Other than that, this is a great app for anyone that wishes to learn CW
