Dot Dash: Morse Code

A brass telegraph key under your thumb. See a letter, hear its rhythm, tap it back. Completely free, no ads, fully offline.

Every letter has a rhythm. Dot Dash helps you learn Morse code the way operators always have: by ear, by touch, by repetition.

The practice surface is a brass telegraph key from the 1920s, drawn to work like the real thing. Tap it for a dot. Hold it for a dash. It clicks under your thumb, and on iPhones that support it you feel the rhythm as haptics too.

A short walkthrough shows you dots and dashes the first time you open the app, and then you choose a tier and go:

Easy, for listening. Ten common letters with their patterns always visible. Perfect for your first session.

Medium, for learning. The full alphabet. Patterns fade as you tap, so your memory does the work.

Hard, for remembering. Letters and numbers, by sound and feel alone. You are hearing the rhythm now.

Three speed presets use the Farnsworth method: characters always sound real, and the slower settings simply give you more room to think between them. A full reference chart is one tap away, and tapping any letter plays its rhythm out loud.

When a session ends you get a recap in plain English, plus a short quote from the history of telegraphy. Every quote is real, sourced, and public domain.

No scores. No timers. No streaks. Nothing to keep up with. Just you and the pattern.

Dot Dash works entirely offline and collects nothing. I built it because Morse is a small, beautiful skill, and learning it should feel like tapping out messages by lamplight, not grinding a curriculum.

Completely free. No ads. No data collected. Ever.
