About this app

Learn Morse code the easy way, a few minutes a day. Whether you're a ham radio beginner, a scout, a puzzle fan or just curious, this Morse code trainer and CW trainer takes you from your first dot and dash to reading words, callsigns and real on-air exchanges.

HEAR IT, SEE IT, TAP IT
Every lesson teaches two new symbols. Hear each one, see its dots and dashes, pick it out by sound, then tap it out yourself, first with the code shown and then from memory. Short reviews bring back what you learned, so it sticks.

TRAIN YOUR EAR LIKE A CW OPERATOR
Listening quizzes teach you to recognize letters by their rhythm, the way real CW operators do, instead of counting dots and dashes. Turn on Farnsworth spacing to hear letters at full speed with longer gaps while you learn.

TAP LIKE A TELEGRAPH KEY
Tap for a dot, hold for a dash. The built-in key shows your code as you tap and measures your sending speed in words per minute (WPM).

LEARN BY SOUND, FEEL OR SIGHT
Choose how Morse reaches you: sound, vibration, a screen flash, or all of them together. Vibration and screen flash are free, so deaf and hard-of-hearing learners can learn Morse code too. With Premium, use your phone as a Morse code flashlight.

PRACTICE YOUR TRICKY LETTERS
The app remembers the symbols you miss and builds quick practice sessions around them, so you spend your time where it counts.

BUILD A DAILY HABIT
Keep a daily streak and get an optional reminder, only on days you haven't practiced yet.

MORSE CODE TRANSLATOR & DECODER
Turn text into Morse code or decode Morse code back into text. Play it as sound, copy it, or share it with friends.

MORSE CODE ALPHABET CHART
Every letter, number, punctuation mark, signal and abbreviation in one searchable chart. Tap any symbol to hear it, or search by its code.
