Cadenza
Read full descriptionHide full description
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 GO FURTHER WITH PRO - Copy whole words, random groups and full lines of text - Your lists: drill your own words, callsigns and contest exchanges; the QSO simulator answers your own callsign - Head copy with no typing - Sending practice with an on-screen straight key - Realistic on-air modes: callsign trainer, QSO simulator and pile-up - Detailed analytics: confusion matrix and reaction time WHY CADENZA No accounts. No ads. No tracking. Everything works offline and your practice stays on your device. Where other trainers make you count or stare at charts, Cadenza keeps you listening. PERFECT FOR - Total beginners learning from zero - Aspiring and licensed ham radio operators preparing for on-air CW - Anyone who wants a durable, offline skill Free forever: the full Koch trainer, the reference, the tools, the daily challenge and basic stats.
