About this game

Ever thought "it'd be cool to know Morse code"?

Maybe it was a movie scene. Maybe a survival show. Maybe you just liked the idea of a secret language made of dots and dashes. Whatever it was — that curiosity is all you need to start.

ditdah turns that "I always wanted to learn this" feeling into actual skill. No prior knowledge needed. Just you, the rhythm of dit and dah, and a retro telegraph aesthetic that makes the whole thing feel like stepping into a different era.

No ads. No tracking. No subscription.

THREE WAYS TO PRACTICE

▸ Listening
Hear Morse code and identify the character. Adjust speed (WPM) with Farnsworth timing — a proven method that builds real decoding reflexes.

▸ Tapping
Send Morse code yourself. Choose 2-button mode (tap dit or dah) or 1-key mode (timing-based, like a real telegraph key).

▸ Conversation (Premium)
Practice realistic QSO exchanges — the kind ham radio operators use on the air.

▸ TRACK YOUR PROGRESS

See which characters you've mastered on the Morse tree heatmap. Check your weekly activity dots on the home screen. Set a daily learning reminder so you never skip a day. Every attempt is tracked per character — you always know what to work on next.

SEE THE CODE

The Morse binary tree shows your position as you decode. Dit goes left, dah goes right. Watch the path to each character unfold in real time.
