## Koch Trainer Description
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.

Thank you and 73,

## Koch Trainer Reviews in United States

### ***-- "Koch trainer App"
Every other CW App is a toy by comparison. However, it has bugs, namely a transient miss sending (at the outset) when using an iPhone.
-- Rangijay, 2025-04-29

### *---- "Needs updating"
With iOS 18.3, this app is unstable and crashes. It hangs when changing WPM. Will not play on iPhone speaker, regardless of mute/volume settings. Headphones required. I’d like my money back.
-- Philm35, 2025-03-13

### **--- "Speed and weight"
I wish that the weight of the characters and speed that are sent could be varied.
-- Yak Dave, 2024-08-12

### *---- "App does not run"
This app does not run. Tried to get a refund and could not.  Do not purchase!!
-- Terry Sr, 2024-05-06

### *---- "Does not work on iPhone 11"
Bought this app.  Downloaded it 5 different times and it crashes immediately.  Morse It is 1000x better and has a Koch Trainer in it.
-- CQ DE C, 2022-12-15

### *---- "Wont open"
App wont open
-- obvit, 2022-11-25

### ***** "Best ever way to learn Morse."
I took my ham radio exams years ago when Morse was required in order to pass, but I never used it much (lazy)!  Now 30 years later I want to re-learn Morse and this is definitely the best way to do it. I want to be proficient at 13 wpm, so I am starting at 13 wpm with the “Koch speed” set to 18. Also, now in my mid 70s, I need something to keep the brain from atrophying…this is certainly doing just that. Great App!
-- giles#2, 2022-04-01

### ***** "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

### ***** "To the point"
If you want to practice CW using a Farnsworth approach (run letters at fast wpm but use additional space in until you speed up) then this app is what you want.  No thrills, but I’m not looking for thrills!  To the point CW practice.  I have used it for years on MacBook.
-- Arc5Coder, 2020-05-09

### ***** "Fantastic app and it’s a steal"
Best CW app for macs.  Koch is the best CW method and this is the best of the best apps to learn code. It is all you’ll need to master CW at high speed. There is a problem with lack of speaker sound on older I-pads like mine without a mute switch. The developer has not corrected this yet, but it still works great with ear phones. If your listening to code then you will want to use earphones any way.  Works great on I-phones and Mac computers.  Negative reviews regarding sequence of letters display their ignorance of the original Koch protocol.  The negative review regarding the objective to spelling a vulgar word is just stupid. I love this app and it doe the job.
