DahDah

Learn Morse by ear and send it with a key of light. Light the lighthouse, knock from the rubble and tune the radio in 19 rescue stories. No account, no ads.

DahDah teaches Morse code the way radio operators learn it: by ear and by touch, not by memorizing a chart. The two dashes in the logo are “dah-dah”: the letter M.

LEARN • 8 modules, 23 lessons: basics, letter groups, numbers, punctuation and prosigns • Hear every letter first, then send it with the key of light • Varied drills: true or false, see and pick, word decoding • Emergency communication: SOS, light and knock signals, Q codes

THE KEY OF LIGHT Tap for a dot. Hold and the light stretches into a dash. Pause and the letter is decoded. You see and feel the rhythm.

STORIES 19 rescue stories and 72 missions, each chapter with its own pixel-art scene. Light the lighthouse in a storm, knock on a pipe from under the rubble, send a distress call from a sinking ship, tune the radio to the right frequency. Three stories are inspired by real events (RMS Republic 1909, the Tham Luang cave rescue 2018, amateur radio on the space station). Every story has its own ambience and music.

The first 3 stories are free. A one-time “All Stories” purchase unlocks the other 16; no subscription. Lessons, practice and races are free.
