Morse Tutor: Learn Morse Code by Touch and Ear

Tap out dots and dashes, listen to beeps, and copy what you hear, with strict timing checks and one named hint per mistake. Six levels take you from first dits and dahs to phrases.

Morse Tutor is a free web app that teaches Morse code by touch and ear: all 26 letters, all 10 digits, and the common prosigns SOS, AR, and SK. You tap with a button, the spacebar, or mic claps, and the app checks your timing against the standard rules: a dit is 1 unit, a dah is 3 units, gaps inside a letter are 1 unit, gaps between letters are 3 units, and gaps between words are 7 units. Every mistake gets one named hint within about a second, such as "That dah was too short, hold it longer" or "That gap split one letter into two". Copy mode plays beeps for you to decode, at speeds you choose. Quiz mode, points, streaks, ranks, badges, and a progress dashboard, with confetti and chimes you can switch off. Everything runs on your device: no audio is recorded, uploaded, or sent anywhere. It is a home practice tool, not a teacher.

The timing rules

One unit is 1200 divided by your speed in words per minute, the PARIS standard. At the default 12 words per minute, one unit is 100 milliseconds. Presses shorter than half a unit do not count. From half a unit up to 2 units counts as a dit, from 2 units up to 4 units counts as a dah, and anything longer is rejected as too long. Gaps follow the same midpoint logic: under 2 units stays inside a letter, 2 to 5 units separates letters, and 5 units or more separates words. The app shows the exact thresholds, so a rejection is never a mystery.

Six levels, from first dits to phrases

Level 1 starts with the first dits and dahs: E, T, I, M, S, O, A, N. Later levels add the rest of the alphabet, then digits, then prosigns and short words built from letters you know. Level 5 covers SOS (three dits, three dahs, three dits as one run), AR (end of message), and SK (end of contact), plus short words. Level 6 covers whole phrases with real word gaps of seven units. Each item has a tip explaining its pattern, and you only move on when your timing passes.

Copy mode: listen, then decode

In copy mode the app plays beeps and you type what you hear. Speed is adjustable, so you can start slow and raise the pace as your ear improves. Wrong copies show the correct code for the letter, not just a score, so every miss is also a lesson. Tap mode and mic-clap mode use the same timing engine, so switching input methods never changes the rules.

Friendly named hints

Every mistake gets one specific hint within about a second: "That dah was too short, hold it longer", "That dit ran long, that was a dah", "Gap too long, that split one letter into two". Wrong versions are rejected clearly, and the built-in test suite proves every rule with synthetic tap sequences, including the wrong versions that must fail. A wrong answer never just shows a score: it always tells you what to fix.

Quiz mode, ranks and badges

Quiz mode turns items into a scored test, with points, day streaks, and ranks that rise as your points grow. Badges mark the milestones: first pass, first prosign, a perfect round, a 7-day streak. A short chime sounds on a pass and confetti falls on a win, and both can be switched off. Practice stays the core: the game elements are seasoning.

Your audio never leaves your device

In mic mode, sound is measured in your browser and immediately discarded, and the microphone turns off the moment you leave the lesson. In tap mode the microphone is never used at all. Nothing is recorded, uploaded, or shared. The page security policy blocks connections to every outside server, and the built-in Offline proof panel shows a live log of every network request the page makes, lets you simulate a fully offline session, shows exactly what is stored on your device, and deletes it all with one button. The app works offline after your first visit.

Frequently asked questions

What is Morse Tutor?

A free web app that teaches Morse code by touch and ear. It covers all 26 letters, all 10 digits, and the prosigns SOS, AR, and SK, with strict timing checks and one named hint per mistake. Everything runs on your device.

What are the Morse timing rules?

A dit is 1 unit, a dah is 3 units, gaps inside a letter are 1 unit, gaps between letters are 3 units, and gaps between words are 7 units. One unit is 1200 divided by your speed in words per minute, so at 12 words per minute one unit is 100 milliseconds.

How do I enter dots and dashes?

Tap with an on-screen button, the spacebar, or mic claps. All three use the same timing engine. In tap mode the microphone is never used; in mic mode it turns off the moment you leave the lesson.

What happens when my timing is wrong?

One specific hint within about a second, such as a dah held too short, a dit run long, or a gap that split one letter into two. A wrong answer always shows the named hint, never just a score.

What do the six levels cover?

Six levels: first dits and dahs, then the rest of the alphabet, then digits, then prosigns and short words, then whole phrases. Level 5 covers SOS, AR, and SK plus words built from letters you know.

Can I practise listening, not just tapping?

Yes. Copy mode plays beeps and you type what you hear, at an adjustable speed. Wrong copies show the correct code for the letter, so every miss is also a lesson.

Does it work offline?

Yes, after your first visit. The app is saved on your device, so everything works with no network. The Offline proof panel even lets you simulate a fully offline session.

Is my audio recorded or uploaded?

No. In mic mode, sound is measured in your browser and immediately discarded. In tap mode the microphone is never used. Nothing is recorded, uploaded, or shared.

Is there a test mode?

Yes. Quiz mode turns items into a scored test, with points, day streaks, ranks, and badges for milestones like a first prosign or a perfect round.

Can it replace a radio course?

It is a home practice tool, not a teacher. Feedback is automatic and can be wrong. For real instruction, learn from the amateur radio community, linked on the Resources page. Morse code is a hobby skill here, not emergency training.

Can I delete my data?

Open Offline proof on the home page and press Delete all my data, or clear progress from settings. Everything is stored only in your browser, on your device.

What speed should I start at?

Speeds are adjustable, so start slow and raise the pace as your ear improves. The default is 12 words per minute, and the app shows the unit length at your chosen speed.
