Morse Mastery Get the app

Learn morse code by ear.

Charts of dots and dashes don’t stick. Morse Mastery teaches every letter as a sound, two at a time, until you can understand whole messages by ear, and send them back.

A working key. Press and hold it.

It’s for you if…

  • You are studying for a radio licence and want morse to stop being the hard part.
  • You want a way to call for help that works with a torch, a whistle or a knock on a wall.
  • You have always wanted to learn it and like the idea of a skill most people will never have.
  • You tried a chart once and the dots and dashes never stuck.

Why it sticks this time.

A chart teaches you to count: dot, dash, dot… By the time you have counted, the next letter has gone. So Morse Mastery never shows you a chart. Each letter plays at full speed from the very first lesson, and you learn its sound the way you know a word, without spelling it out. Two new letters arrive, you practise them until they come without thinking, then two more. Radio operators call it the Koch method, and it has been training them for nearly a century.

Over 200 lessons, in 26 sections.

Understand it, and send it.

Many morse apps only teach you to listen. Knowing the code means being able to answer too, so you practise both from the first lesson.

Listening

Listen to letters, then words, then whole messages, and pick what you heard. Set the pitch of the tone and the speed to suit you, from a gentle 5 words a minute up to 40.

Sending

Tap the key on your screen. The app reads back what you sent, so you hear your own rhythm and can fix it.

Hear it, see it, or feel it.

Every lesson can play as a tone, as flashes of your phone’s light, or as vibration in your hand. Practise silently on the bus, or flash a message across a dark campsite.

Sound

A clear tone, through the speaker or headphones.

Light

Your phone’s flashlight, like a signal lamp at sea.

Vibration

Silent, in your hand. One game is played by feel alone.

Each line is SOS, drawn with the exact timing the app uses.

Six games that make practice the fun part.

Lessons teach you the code. The games make you quick with it, a little under pressure, until you forget you are practising. Streaks and 54 achievements keep you coming back.

Questions

I know nothing about morse. Is this for me?

Yes, it starts from nothing. Section 1 teaches two signals, one short and one long, and each section after it adds a letter or two. You never have to memorise a chart.

I tried to learn morse before and gave up. Why would this be different?

Most people learn from a chart, counting dots and dashes, and hit a wall: counting is too slow to keep up with real morse. This course teaches each letter as a sound at full speed from the first lesson, which is how radio operators have trained for decades. And the games make the daily practice something you look forward to.

What is free, and what does the unlock add?

The first 5 sections are free, with no time limit. They teach eight letters, E, T, A, N, I, M, S and O, both listening and sending: enough to send SOS. Morse Turret, Free Tap, the SOS beacon and the full reference are free too. The one-time unlock opens the other 21 sections, all six games, and the timed drills and message practice.

How much is it? Is it a subscription?

It is one payment of $8.99 in the US (the store shows you the price in your own currency). It is not a subscription and nothing renews. On a new phone you restore the purchase from Settings with the same store account, at no charge.

How long does it take to learn?

It depends on how often you practise: a few minutes every day works much better than an hour once a week. The course has over 200 lessons and ends with speed training at 20 to 30 words a minute, a comfortable conversation pace for radio operators.

Does it teach sending, or only listening?

Both, from the first section. You tap an on-screen key, the way you would a real one, and the app reads back what you sent. Many morse apps only teach listening.
