Morse Code Learner
Learn A–Z with Decision Tree
$1.99 · Designed for iPad. Not verified for macOS.
Master all 26 Morse code letters visually - tap DOT & DASH to walk the decision tree, practice with sound & flashlight, and unlock 13 achievements.
LEARN MORSE CODE THE VISUAL WAY
Morse Code Learner teaches you the complete A-Z Morse code alphabet through an interactive binary decision tree - no rote memorization required. Every letter is a unique path of dots and dashes through the tree. See it, tap it, learn it.
HOW IT WORKS
Every Morse code character is built from dots and dashes. In Morse Code Learner, these map to branches of a visual decision tree: tap DOT to go left, tap DASH to go right. Follow the path and land on your letter. Once you can read the tree, you can decode any signal.
FEATURES
Binary Decision Tree Visualization
Your active path highlights in real time as you tap. The tree shows all reachable letters at once - the full map of Morse code in a single glance.
A-Z Progressive Levels
Start with E (the simplest letter) and advance through all 26 letters at your own pace. Complete a letter to unlock the next level. Progress is saved automatically.
Five Training Modes
- Teach - guided lessons with demo playback for every letter
- Rhythm - listen to a pattern, then reproduce it exactly to score
- Game - timed speed challenge across multiple random letters
- Word - encode full words letter by letter
- Sentence - encode complete sentences to build real fluency
Multi-Sensory Feedback
Each signal triggers a 700 Hz tone, a screen flash, and your device's rear flashlight simultaneously - just like a real Morse transmitter.
13 Achievements
Unlock badges for signal counts, daily streaks (3, 7, and 30 days), perfect rhythm rounds, reaching Level 10, and completing the full A-Z course.
Fully Customizable
- Dual-button or single-button input (short tap = dot, long press = dash)
- Adjustable long-press threshold, dot/dash durations, and demo code spacing
- Light, Dark, or System theme
- Mirror tree layout for left-handed or alternative practice
- Individual toggles for sound, screen flash, and flashlight
PRIVACY - 100% OFFLINE
No account required. No data collected. No internet connection needed.
Your learning progress, settings, and achievements are stored only on your device. Camera permission is used solely to control the rear flashlight for signal feedback - the app never captures, records, or accesses any photos or video.
