About this app

Due to changes to the law, please read our privacy policy before purchasing this app.

Take your morse code to the next level with Koch Morse Trainer Pro. The only trainer that supports prosigns (procedural signals) and non-english extensions characters on Android.

Learn or improve your morse code in a short amount of time. The Koch method is designed to teach you morse at full speed. There's no need to learn at slow speeds then re-learn all the characters again once you increase your wpm.

If you wish to start off slow or simply want to pass your 5 wpm morse exam, this app has adjustable speeds to suit your needs.

KMT uses Farnsworth timings like the ARRL use for their transmissions and practice tapes. You can increase the gap between characters so you still learn them at full speed but not feel overwhelmed by the frequency they are sent.

Main Features:

✓ Character and word speeds are fully adjustable between 5 and 50 wpm
✓ Eight modes: random, 100 common words, 1000 common words, (German users can also select 100 and 1000 common German words), QSO (includes prosigns), callsign, morse abbreviations, custom text (which also allows you to input & practice prosigns also), and RSS Feeds
✓ Test yourself! Input what you're hearing and calculate your results to see how well you're doing
✓ Warm up feature which plays the latest character prior to the main session
✓ Character setup option screen to include/exclude characters, such as punctuation, prosigns and non-english characters - this also allows you to learn additional characters
✓ Adjustable group size with option to fix size in random mode
✓ Adjustable pre-session delay and session time (1 minute to 30 minutes)
✓ Adjustable tone frequency (200Hz - 2000Hz)
✓ Background noise (QRM) simulator
✓ Speak feature which tells you the latest character if text to speech is available
✓ Favour recent characters option for those new characters so they are played more often
✓ Display character before or after it's sent
✓ Plus lots of customisable options to change

This is a very comprehensive trainer, one I will enjoy using. My only issue is that the RSS feed output starts jumping from the top of the screen down to the bottom, then back up again between each word, once the text reaches the bottom of the window and has to start scrolling the visible window. This is stomach churning if you're trying to read while listening to the code. Otherwise, this is a really good tutor.

works real well on my samsung tablet with a pair of headphones. Sound quality is ok it doesnt seem to be distorted. Sometimes when I miss a character it gives me credit for a correct answer. Not sure whats up there. It takes a lot of practice to learn the code, but this seeems to help.

Right off the bat, I'm reading the help doc and it says to contact (author) if there's a question. Well, there's a typo in the very first sentence. I tap the link to contact (author) and the web page cannot be reached. Just trying to help. Not a good first impression. Why not make the app absolutely free? That's right free. Then if someone likes the app they send you a donation. I help people learn stuff all the time. Invest my time and energy. For free.
