This app teaches you to 'receive' Morse code.

It starts with two letters and automatically adds more when it understands that you are ready.

This is the easiest and most efficient way to learn Morse code as the app focuses on the practice you need next, instead of wasting your time with stuff you already know or confusing you with stuff that you still don’t.

The original idea comes from Ward K9OX (

By default the app uses the 'Koch' method letter sequence and starts with the first two letters: K and M. But you can use any of the methods available and find the one that suits more your likings. There's also a training program for the top 40 words used during a CW QSO.

Around each letter you have a circle chart showing how high is your error score. It starts from 100% (full circle) and lowers as you start guessing letters right and increases when you are wrong or you take too much time to recognise them.

To start the training, simply press the PLAY button on the top right of the display.

At this point the app will start playing tones. Press the one that you think corresponds to the tone. If you are wrong, the app will let you know by playing an 'error' sound. If you are right, the app will continue by picking up another letter or word. Once you'll become good enough with the active letters, the app will enable a new one following the method selected.

You can decide to put the training lesson on hold by pressing the PAUSE button. Or stop it by pressing the STOP button. If you want to have an automatic stop after a certain amount of minutes, you can set the SESSION TIME in the settings.

While not training, you can tap on any key or word and listen to its tone to start to get used to it even outside of the training session.

You can access the SETTINGS by tapping the 'hamburger icon' on the top left.

You can look at your top 10 scores by tapping BEST SCORES in the left menu.

Important: you can use the app in both landscape and portrait mode!

Enjoy learning Morse code!

I've finally learned all of the characters after trying off and on over the years.

This app, however, is buggy. It freezes often, stops playing the sounds, and sometimes plays two sounds at once.

If you want to learn to copy, get this app

I’ve used two other apps to try to learn the code. One was online and one was on my phone. They were fine, but don’t have the feature that makes me recommend this app.

This app provides immediate feedback to let you know if you recognized a letter. It also doesn’t spoon feed you with new letters. You have to recognize a letter is unfamiliar and therefore new.

I also like the way the app looks and the simplicity of the preferences controls.

Trying out the app has definitely been worth my time. After using the app for a few minutes daily over the last couple weeks, I’m making breakthroughs. This app is a nice compliment to whatever other strategies you’re using to learn the code. For me, I’ve gone further with this app than any other.

If you want to learn to copy, and you should want to achieve that, this is the one app you should start with.
