Cadenza: Morse Code Trainer

New: your lists. Drill your own words, callsigns and contest exchanges by ear, and the QSO simulator now answers your own callsign.

Cadenza teaches Morse code the way real operators actually read it: by ear. You start with just two letters at full speed and add more as you go, so you learn 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 which characters you confuse, drills the exact pairs you mix up, and raises your speed only when you are ready.

WHAT YOU GET

• 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 daily challenge that is the same for everyone
• Three channels: hear it, see it (a gentle beacon or an opt-in strobe), feel it through vibration
