QRS — Morse Code Trainer

Learn CW by sound, not chart

Free · Designed for iPad. Not verified for macOS.

Two letters at real speed, then three, then the whole alphabet — the Koch method that actually works. Tap a straight key and watch the app read your fist. QRS teaches Morse code the way it sticks: by sound, at honest speed, two characters at a time. - Learn: the Koch method. Characters play at real speed from the first lesson; you tap what you heard, and a new character joins when your accuracy holds. No charts to memorize, no counting dits. - Copy: head-copy practice with random groups and real ham-radio vocabulary, with the silences stretched while you're learning (Farnsworth spacing) and honest when you're ready. - Key: a straight key on the screen. Squeeze a dit, lean a dah — the app decodes your sending live, so you can watch your fist improve. - Chart: the whole code, every character playable, for the moments you just have to look. No account, no ads, nothing collected, works entirely offline. No license or radio needed — Morse is a skill you can start tonight. "QRS" is the Q code for "send more slowly." Only at first. Part of the Q-code family: QSX, QRX, QSO, QTH, QRG, QSY, QRV.
