MorseTree — Learn Morse Code

Smart Payment Systems

About this app

MorseTree turns international Morse code into something you can SEE. Instead of memorizing 26 letter codes from a list, you watch a glowing
binary tree light up as you tap dots and dashes. Every letter is a unique path through the tree — once you see it, you can't unsee it. Tap to type. Hold to elongate. Listen to learn.
WHAT'S INSIDE
• A live interactive Morse code tree — all 26 letters visible at once
• Single-button keyer: short tap = dot, long press = dash
• Real-time audio at standard PARIS-timed Morse speed
• Word mode for keying full words with the same single button
• Quiz mode — listen, transcribe in a text field, and check your score
• Three quiz formats: short words, mixed words, full sentences
• Adjustable speed (5 to 40 WPM) and pitch (400 to 1000 Hz)
• Symbol reference for letters, numbers, and punctuation
• Replay any letter or word with one tap

WHO IT'S FOR
• Amateur radio (HAM) operators preparing for CW exams
• Scouts working toward Morse code merit badges
• Aviation enthusiasts learning NDB and beacon identifiers
• Educators teaching binary trees, encoding, or communication history
• Anyone curious about the most elegant binary code ever designed
