Learn Morse Code - CW Trainer2.0.0

Master International Morse Code with a progressive learning system designed for ham radio exam prep, aviation communication, and emergency signaling.

Learn Morse Code transforms your phone into a tactical morse code trainer with authentic audio playback, decode practice, and speed drills that take you from zero to fluent CW operator.

PROGRESSIVE LEARNING SYSTEM
Start with the alphabet, then advance through numbers, punctuation, and prosigns. Each character set builds on the last, with mastery tracking that ensures you never move forward until you're ready.

REAL AUDIO MORSE CODE PLAYBACK
Hear every character as a pure sine wave tone with authentic dit/dah timing. Adjust speed from 5 to 30 WPM and tone frequency from 400 to 1000 Hz. This isn't a recording - it's programmatically generated morse code with proper Farnsworth timing.

DECODE PRACTICE MODE
The real test: listen to morse code audio and identify the character. Train your ear the same way professional CW operators do. Build the reflexive recognition you need for your ham radio license exam.

SPEED TRAINER
Progressive WPM challenges push your receiving speed higher. Start slow, build muscle memory, and work toward real-world CW operating speeds used on amateur radio bands.

FLASHCARD LEARNING
Study every character with visual morse code display and instant audio playback. Tap to hear, tap to reveal. Simple and effective memorization.

HAPTIC FEEDBACK
Feel the dit-dah pattern through your device. A tactile dimension that reinforces timing patterns and helps encode morse rhythm into muscle memory.

PROGRESS TRACKING
See exactly where you stand. Mastery percentages for Letters, Numbers, Punctuation, and Prosigns keep you motivated and focused on weak areas.

TACTICAL DARK INTERFACE
A modern aviation HUD-inspired design that's easy on the eyes during night study sessions. No clutter, no distractions - just clean tactical aesthetics built for focused learning.

COMPLETELY OFFLINE
No account needed. No permissions required. No internet connection necessary. Your progress saves locally. Learn morse code anywhere: on a plane, in the field, off the grid.

NON-INTRUSIVE ADS
Small banner ads only. No popup interruptions. No forced video ads breaking your focus mid-lesson.
