Morse Mastery Get the app

From your first dit to your first QSO.

Morse Mastery is a 26-section course that teaches you to hear morse and to send it, one or two letters at a time, until you can hold a real radio conversation. Learn by sound, by light or by vibration, and play six games that make it stick.

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

This is a real key. Hold it down.

Twenty-six sections. Every one of them builds on the last.

The course follows the Koch method: each character is sent at full speed from the start, so you learn what it sounds like, not how to count its parts. A letter or two arrive, you drill them until they are automatic, and then the next. Over 200 lessons in all.

Receive and send, from the first lesson.

Knowing what a letter sounds like and being able to send it are different skills, and an operator needs both. The course teaches them side by side, and the free start includes sending.

A receive lesson

Hear it

Copy letters, then words, then callsigns, by ear. Tone and speed are yours to set, from 400 to 1000 Hz and 5 to 40 words per minute.

A send lesson, on the tap key

Send it

Key on the screen the way you would on a real key. The app reads back what you sent, so you hear your own rhythm and fix it.

Sound, light, or vibration.

Every signal in the app can play through any of the three. Learn on a quiet train by feel, or flash a message across a dark campsite with your camera light.

Sound

A clean tone through the speaker or wired headphones.

Light

Your phone’s flash, the way a signal lamp sends at sea.

Vibration

Silent, in your hand. Safe Cracker is played this way alone.

Above: SOS, drawn with the exact timing the app uses.

Morse Turret

Six games, each training something different.

Drills teach the code. Games make you fast with it, under a little pressure.

  • Signal Intercept

    Receive

    Decode enemy transmissions before the signal fades out.

Questions

What is free, and what does the unlock add?

The first 5 sections of the course are free, with no time limit: E, T, A, N, I, M, S and O, receiving and sending, which is 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 copy practice.

How much is it, and 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. Get a new phone and you restore the purchase from Settings on the same store account, at no charge.

Do I need an account? Does it need the internet?

No account, no sign-in, no email address. The app makes no network requests of its own and works the same in airplane mode. Your progress is stored only on your phone; you can export it to a file from Settings whenever you like.

Are there ads or tracking?

No ads, no analytics, no tracking, no third-party SDKs. The privacy policy explains the few things that do touch the system, such as the store’s own purchase and rating dialogs.

I know nothing about morse. Where do I start?

At section 1, which teaches two signals: one short, one long. Each section adds a couple of characters and drills them until they are automatic, so you never have to memorise a chart.

Does it teach sending, or only listening?

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