About
Morsel turns your iPhone into a small Morse code instrument. You learn the way radio operators do: by rhythm, not by memorizing charts of dots and dashes.
HEAR, FEEL, KEY
Every letter plays as sound, as haptics you feel in your hand, and as light on a moving tape. Then you key it back on two keys, DOT and DASH, and the instrument tells you what it heard.
A COURSE THAT BUILDS
Lessons introduce a few new letters at a time at full letter speed (the Koch method), with spacing that tightens as you improve. What you hear decides when a lesson is passed, and checkpoints confirm what you know. Take a lesson FULL or QUICK, then go straight on with NEXT LESSON. After lessons in a row, THIS SESSION sums them up and offers a short check without hints. A review brings back the letters you are about to forget. The course covers all 26 letters, the numbers and the common signs.
AN OPEN COURSE
With Morsel Pro you can begin any lesson; one that is ahead of you says which lesson is best first. PRACTICE WITH chooses what SEND and HEAR drill: this lesson's letters, everything so far, or all 26.
SIGNAL QUIZ
Twenty mixed questions and no clock: name the letter you hear, tell two sound-alikes apart, copy short words, or key what you hear. Your best score for each set is kept.
MODES
SEND: key the letter shown. HEAR: name the letter you hear. FREE: key anything and watch it decode, or type a message and send it as sound, haptics, screen light or your flashlight. CHART: every sign, to hear and feel on demand, in course order, standard order, or as a tree where a dit branches left and a dah branches right.
HELP WHEN YOU WANT IT
RHYTHM WORDS gives each letter a short phrase that carries its beat. The Field Manual explains timing, spacing and the method, with demonstrations you play yourself.
FOR EVERY LEARNER
Learn by touch alone with sound off, or by light alone. Dynamic Type, VoiceOver, Reduce Motion and a reduced-flashing option are supported, and a hardware keyboard keys too. On iPhone Duo, the instrument fits the phone folded or open, in portrait or landscape.
WIDGETS AND CONTROLS
Next Lesson, Letter of the Day and Practice Log widgets, plus Control Center controls to start practicing in one tap.
PRIVATE BY DESIGN
No account and no ads. Your progress stays on your iPhone. Optional usage data uses a random identifier and is sent only if you choose to share it. You can change that anytime.
