Farnsworth

Full-speed characters, stretched spacing — the way slow code is meant to be taught.

Real callsigns

Practise against actual CQQRS net regulars, not random letters.

Works offline

Clean sidetone, your speed and pitch, no signal needed in the field.

Install on Android

Tap Download for Android above, then open the file on your phone. The first time, Android asks you to allow installs from this source — that's expected for an app outside the Play Store. Allow it once and the install proceeds.

iPhone: a TestFlight build is on the way. Check back here.

Callsign lists

The app keeps its practice callsigns current by checking here for updates, so new net regulars show up without reinstalling.
