MorseCue is a quiet daily practice for Morse code — heard, seen, and felt. An old language with a deep accessibility legacy, rebuilt the most Apple way.
Every character arrives through three channels at once, so the rhythm sinks in faster — and so it works for everyone.
Pure 700 Hz sine, synthesised in real time with a 6 ms envelope so there's not a single click. The same engine a radio operator's ear was trained on.
Code rendered as calm glyphs, never cramped text. A mastery map shows the alphabet filling in, one quiet square at a time.
Core Haptics taps the exact rhythm into your hand. Practise with your eyes closed, or learn it without hearing at all.
Open MorseCue, listen to ten signals, close it. The plan is deterministic each day — review what's due, meet a new letter when you're ready.
No flashy gimmicks — just the techniques operators have trusted for a century, made effortless.
Start with two characters at full target speed. The next one unlocks only when you're consistently right — speed never becomes the wall.
Each character returns exactly when you're about to forget it. Quietly scheduled, so you never decide what to study.
MorseCue notices the pairs you mix up — K and R, S and H, U and V — and weaves them back in until they click apart.
Farnsworth spacing keeps letters crisp while the gaps tighten. Climb from 5 to 20 WPM, one rung at a time.
Accessibility isn't a setting we bolted on. Morse itself is an assistive language — and MorseCue treats it that way from the first tap.
Every control is labelled and ordered for screen readers. Dynamic Type scales to the largest sizes without breaking the layout, in light and dark with WCAG AA contrast.
Audio-first helps low-vision learners; haptics open a fully eyes-free path; clear glyphs serve those who learn by sight. Reduce Motion is respected throughout.
Morse is an official Switch Control input method on iPhone — a bridge for people with motor or speech differences. Learning it here is practice that can matter.
