Code sprint: Morse typing trainer
A Morse typing trainer: a word appears, and you type it in dots and dashes, letter by letter. Hints show the codes until you know them; then take a timed typing test.

How to use
- Pick a round (30, 60 or 120 seconds, or No clock), what to send (Words or Letters) and the hints (Until learned is best to start).
- Choose Two keys (a dot key and a dash key) or One key (tap for a dot, hold for a dash).
- Press Start. Type each letter of the word in Morse: J or “.” for a dot, K or “-” for a dash, then Space to finish the letter.
- If the code turns red, it can't be the letter: press Backspace and fix it. Miss a letter twice and its code is shown.
- When the round ends, read your speed and the letters to practice, then go again.
What it does
Code sprint trains you to type Morse code fast and right.
- Hints that fade. With Until learned, each letter's code shows until you have sent it right first time three times; then it disappears.
- Words or single letters. Send words such as SOS, CQ and HELLO, or one letter at a time from A to Z.
- A typing test or calm practice. Rounds of 30, 60 or 120 seconds score you in WPM; No clock keeps no best score.
- One key or two. J and K (or “.” and “-”) as on Gboard's Morse keyboard, or one key read by how long you hold it.
- A live check. The code turns red the moment it can't be the letter.
- A recap. Letters a minute, WPM, accuracy, and the letters that gave you trouble, with their codes.
- Best scores for each round length, words and letters apart, kept on this device, and a daily challenge from the games page (60 seconds of words, hints after 2 misses). Switch tabs and the clock pauses until you resume.
How it works
The codes are the International Morse code (ITU-R M.1677-1). Each letter you finish is checked against its code; a right letter scores and moves on, a wrong one is tried again.
Hints. There are three settings:
- Until learned keeps a count for each letter on this device: send it right first time three times in a row and its code stops showing; miss it and the count starts again.
- After 2 misses shows a code only when you miss a letter twice.
- Always shows every code, for your first rounds.
Speed. The recap gives letters a minute and WPM, counting five letters as a word, as typing tests do: 60 letters in a minute is about 12 WPM.
One key. A short press is a dot and a long one a dash. The dash point starts at 300 ms and then moves to the middle of your own dots and dashes (after at least two of each among your last 12 presses).
The letter is sent when you pause for 2.5 times the dash point, between 350 and 900 ms, or at once with Enter.
Examples
Practice words and what it takes to send them with Two keys:
| Word | Morse code | Marks | Key presses |
|---|---|---|---|
| SOS | ... --- ... | 9 | 12 (9 marks, 3 Spaces) |
| CQ | -.-. --.- | 8 | 10 |
| HELLO | .... . .-.. .-.. --- | 16 | 21 |
| MORSE | -- --- .-. ... . | 12 | 17 |
CQ is the radio call “calling any station”. Typing HELLO in 10 seconds is 30 letters a minute, about 6 WPM.

About Code sprint
What is a good Morse code trainer?
A good trainer uses real Morse sound and timing, shows codes while you learn and then takes them away, and tells you which letters you miss. Code sprint does the last two for typing, with a sidetone as you send.
For copying by ear at real speed, the Koch method course teaches letters at full speed, two at a time. To compare apps and programs, see Morse code practice software.
Is this a Morse type test?
Yes, for Morse code: pick a 30, 60 or 120 second round, and Code sprint scores the letters you send right, with your speed in WPM and the letters you missed. The "Morse type" exam some schools use is a quiz format, not Morse code, so this page doesn’t cover it. To test reading or hearing Morse instead of sending it, use the Morse code quiz.
Is this Google’s Morse Typing Trainer?
No. Google’s Morse Typing Trainer for Gboard (2018) teaches single letters with picture hints and no clock. Code sprint is a separate trainer on this site: it uses the same J and K keys, fades its hints as you learn, and adds words, timed rounds, one-key typing and a recap of your misses.
Is there a way to learn Morse code?
Yes. Learn the sound of each letter first, then practice sending it. The Koch method course starts with two letters and adds one at a time.
Use Code sprint with Until learned hints to learn the keying, and the Morse code alphabet as a chart.
What is the best device for learning Morse code?
A phone or a computer with sound is enough to start: the Morse code alphabet, an ear trainer and a typing trainer all run in a browser. A real key comes later, when you want to send by hand; the keyer page reads one through your keyboard.
Is there an app that teaches Morse code?
You don’t need to install one. This trainer, the Koch method course and the games run in any browser on a phone or a computer. To type Morse in other apps, add Gboard’s Morse layout; the steps for iPhone and Android are on the Morse keyboard page.
How fast should I type Morse code?
Accuracy first: aim to finish most rounds above 90% right, then raise the speed. Code sprint shows letters a minute and WPM after each round, so you can track your own progress against your best score for each round length.
Trust and limits
Private by design.
Honest about limits.

Code sprint runs in your browser: nothing you type is sent anywhere, and your best scores, learned letters and key style are saved on this device only.Know the limits
Keys and words
The words come from a fixed list of 69. One key is read from the length of each press, so a very uneven rhythm can still turn a dot into a dash; Two keys is exact.ITU-R M.1677-1
Tested against the standard
It uses the International Morse code (ITU-R M.1677-1) for the letters A to Z. Each letter you send is compared with the International Morse code table, and the scoring rules (the live check, the hints, the recap and the WPM figure) are covered by automated tests.
