Cadenza: Morse Code Trainer

Cadenza teaches Morse code the way real operators read it: by ear. You start with two letters at full speed and add more as you go, learning the sound and rhythm of each character instead of counting dots and dashes.

Built on the proven Koch method with Farnsworth spacing, Cadenza adapts to you: it notices the characters you confuse, drills the exact pairs you mix up, and raises your speed only when you are ready.

What you get for free
- Letters trainer: the full alphabet, numbers and punctuation, one character at a time
- Reference: tap any letter, prosign, Q-code or abbreviation to hear it
- Tools: Listen, a decoder that turns clean Morse tones into text through your mic, a text-to-Morse translator (sound, screen light, camera flash, vibration) and an accessible Morse keyboard
- Postcard: turn a short message into a Morse card, drawn as a rhythm score and sent as a picture with a link. Your friend hears it and decodes it in Cadenza
- Progress: streaks, a daily goal, achievements, accuracy heatmaps and a shared daily challenge
- Three channels: hear it, see it (gentle beacon or opt-in strobe), feel it through vibration
