Amateur radio apps for iOS

QRS is a Morse code trainer.
QRS collects nothing. There are no accounts, no analytics, no advertising, and no tracking. Everything the app teaches is built in; nothing is fetched from a network.
Your learning progress (which characters you’ve unlocked and your recent accuracy) and your speed settings are stored on your device and never leave it.
