## Description

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.
