## Description

Morse code, finally a game. Tap to the rhythm of dit and dah and learn 41 characters with the Koch method the pros use. SOS & CQ practice free. No ads, fully offline.

A 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 and punctuation
- 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

RHYTHMMORSE PRO
- All 40 Koch levels

- Custom Practice: smart drills weighted toward your weakest letters
- Daily Challenge archive: replay any of the last 14 days
- Confusion matrix and WPM history analytics
