Koch method from the first session: full-speed characters, Farnsworth spacing, copy and Send modes, and mastery meters per character.
NATO / ICAO phonetic
Alfa to Zulu with timed drills in both directions — hear-and-type and see-and-say — until callsigns roll off automatically.
Ham-radio Q codes
QTH, QRZ, QSL and friends, each drilled in question and statement usage the way they're actually exchanged on air.
Built to stick
Spaced repetition schedules every review, streaks keep you honest, and live On Air rooms let you practice with real people. Installable PWA, offline capable.

Frequently asked questions
How fast can I start reading Morse?
Your first characters play within 60 seconds of opening the app. Koch starts at full character speed with two characters and adds more only as your accuracy holds.
What is Farnsworth timing?
Characters sound at full speed while gaps between them are stretched — you learn each character's true rhythm from day one, then compress the spacing.
What does the free license include?
The first 10 Morse characters, 10 NATO letters, 5 Q codes, and 25 daily reviews — free forever.
What does Pro add?
Full catalogs, unlimited drills, Send mode, and On Air rooms — €9.99/week auto-renewing or €29.99/month, cancel anytime.
Does it work offline?
Yes. re:c0de Radio installs as a PWA; drills and progress work offline, On Air rooms need a connection.
