Visual Morse code trainer
Morse Tree
A mobile Morse trainer that makes the code visible first, then teaches learners to hear it. Morse Tree turns dots and dashes into paths, synchronizes those paths with audio, and keeps the whole experience private and offline.
The problem
Morse code is easy to look up and hard to actually hear
Most Morse learning tools force beginners into either static memorization charts or abstract audio drills. Learners understand the symbols, but they struggle to hear patterns, build confidence, and keep practicing long enough to reach useful fluency.
Learning loop
From tree path to audio recognition
See the path
Every dot and dash moves through the Morse tree, turning each letter into a route learners can understand.
Hear the signal
Synchronized tones help learners connect the visual path to the sound pattern they need to recognize.
Key it yourself
Large dot and dash controls let users practice by touch while the tree responds in real time.
Fade the crutch
The visual model is the bridge. The long-term goal is confident audio-first recognition.
Capabilities
What Morse Tree does
Audio-synced traversal
Tree highlights follow the timing of each dit and dah, so the learner sees what they hear.
Built for mobile practice
A focused Flutter app designed for short, repeatable learning sessions on iOS and Android.
Offline by default
Lessons, keying, playback, and settings work without accounts, servers, or network access.
Accessible learning surface
Screen-reader labels, haptics, and reduce-motion support are treated as core product behavior.
Private local storage
Settings and onboarding state stay in the app's private storage and are removed on uninstall.
Designed for fluency
The tree teaches structure, while audio practice pushes learners toward real Morse recognition.
Who it's for
Built for learners who need Morse to click
Scouts, educators, and facilitators introducing Morse code visually
Ham-radio learners who want a friendlier path into CW practice
Curious adults looking for a focused offline learning tool
Learners who benefit from audio, visual, and haptic reinforcement
Product principles
Small app, clear contract
Turns every letter into a path instead of a lookup table
Bridges visual understanding into audio pattern recognition
Works without accounts, servers, or network access
Built as a native-feeling Flutter app for iOS and Android
