Morse Mastery Get the app

Stop counting dots. Start hearing letters.

Morse Mastery is a complete course that teaches morse code the way radio operators learn it: by sound, at real speed, two letters at a time. It takes you from your very first letter to a real radio conversation.

The first 5 sections are free, with no time limit. The whole course is one payment of $8.99.

The course: 237 lessons on one path, from your first letter to a radio conversation.

Try it here. Hold the key.

A short press is a dit, a long one is a dah. Send three short, three long, three short, and the key spells out SOS as you go. This is the same key the lessons use.

Try S: three short taps.
Then O: three long ones.

Hear it, send it, play it.

Under a minute of the app itself: listening, sending, practice that finds your weak letters, the course and all six games. Sound on.

Charts make you count. Real morse is too fast to count.

C
On a chart, C is four symbols to look up and count.
C
0.66 seconds
On the air, C is one sound, gone in 0.66 seconds. You learn to recognise it, the way you recognise a word.

So Morse Mastery never hands you a chart. Every letter plays at 20 words a minute, the speed operators use, from the very first lesson, with extra space between letters while you learn. You get two new letters at a time, until they come without thinking. It’s called the Koch method, and radio operators have been trained this way since the 1930s.

Morse has two halves. You learn both.

Understanding morse and sending it are different skills. Every section trains both, so you can answer, not only listen.

A listening lesson: tap the character you hear

Listening

Hear letters, then words, then whole messages, and tap what you heard. Set the tone’s pitch and your speed, from a gentle 5 words a minute up to 40.

A sending lesson marking a Q as spot on, with each dit and dah measured

Sending

Tap the key on your screen. The app checks the letter you sent and measures every dit and dah against the ideal, so you can see your rhythm and fix it.

Learn it by sound. Or by light. Or by touch.

Every lesson works through the speaker, the flashlight or 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, keyed with the exact timing the app uses.

A light lesson: read the letter from the flashing lamp

29 true stories, told between the lessons.

Morse has changed the world more than once. The course tells you how, a few minutes at a time, so you know what the code you’re learning has done.

  • The Painter’s Grief

    Why a celebrated portrait painter spent twenty years finding a way to send news faster than a horse.

  • Two Weeks to Two Minutes

    The cable laid across the floor of the Atlantic, and the Queen’s message that took 16 hours.

  • Beethoven’s Secret Code

    The four notes the BBC played to occupied Europe, and why they spell V.

  • Blink: TORTURE

    The prisoner of war who told the truth with his eyes, on camera, in 1966.

  • The Last Transmission

    The night a French coast station sent its final words in morse.

  • Bounced off the Moon

    How radio operators talk by echoing morse off the Moon, 2.5 seconds there and back.

Six games, so practice never feels like practice.

Lessons teach you the code. The games make you quick with it, under a little pressure. 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.

All 12 questions

Start with E and T.

Section 1 teaches your first two letters by ear, and has you sending them. It’s free.
