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.

This is a great program why?

1 you can adjust to any speed you like
You can start at 5wpm or higher
2 you learn by sound of the letters
3 spacing arrangements. Space at 5 wpm but send the letters at 30 wpm
4 this is a serious tool- don’t challenge the order of the letters ,numbers etc
5 hear m - - k -.- associate sound with the letter that’s where speed comes in
6 you could start at 20 or 30 wpm!

I trained myself in 1976 when I became a ham operator. I studied the letters then the sound- wrong . It’s sound associate the letter or number or punctuation.

Do it in your head. Don’t write it down
Good luck

Great tool for learning CW

The current version does everything I need it to do.
Uses Koch method and Farnsworth timing as recommended by most CW mentors. Works as advertised. Scratch pad feature is helpful as well.

I'm a novice with CW and this app is Definitely helpful in building skill.

Could it be improved by adding more features? Sure. But it does the job well and it's priced right.

Great job by the Pignology team.
