RhythmMorse: Learn Morse Code

New in 1.1: try Pro free for 7 days. Smart custom practice, a 14-day Daily archive, live achievements — and SOS/CQ transmit practice is now free for everyone.

The world's first Morse code app that actually feels like a game.

Tap to the rhythm of dit and dah. Learn real Morse with the Koch method — the technique radio operators have trusted for decades — and build a daily streak that sticks. No ads. No account. Fully offline.

WHY RHYTHMMORSE

• Morse is rhythm. Instead of staring at a chart of dots and dashes, you tap them: your fingers learn the timing while your ears learn the sound.
• Perfect / Good / Miss judgments, combos and a fever mode turn every drill into a round you want to replay.

LEARN THE KOCH WAY

• 40 levels covering all 41 characters: A-Z, 0-9, punctuation and prosigns
• Start with just two characters at full character speed, then add one at a time
• Adjustable tone frequency, WPM and Farnsworth timing, plus input calibration

MODES

• Rhythm Play: Normal, Speed Run and Survival
• Listening Quiz: hear the code, pick the right character
• Daily Challenge: one seeded run per day — the same puzzle for everyone
• Transmit Practice: key SOS and CQ free on the straight-key trainer

STAY ON TRACK

• Daily streaks with gentle reminders, XP and player levels
• 26 achievements and three fresh daily missions every day
• Per-character accuracy heatmap
