Daily Morse turns Morse code practice into a daily habit. Every day brings one fresh, evergreen tech passage — the same for everyone — so there is always something new to copy and send. FREE TO TRY Start with 7 days of full access, free, with nothing to cancel. After that, daily Listen practice and Standard keying on the on-screen key stay free for good. A single one-time unlock keeps everything else: every lesson, the Koch course, the QSO simulator, your stats, Mic Key and Expert keying. No subscription, and Family Sharing lets your whole family use it. Already bought Daily Morse? You keep everything automatically. THREE WAYS TO PRACTICE • Listen — Hear the day's message in clean Morse at a speed and spacing you choose. Hide the text and copy by ear, then reveal it to check yourself. • Key — Send the message yourself on an on-screen straight key, or use a real key or buzzer through your device's mic. Choose Standard or Expert timing so it feels right whether you are under 12 WPM or well past it. • Learn — Guided lessons that build up gradually: small groups of letters, then numbers and symbols, then full reviews. Listening lessons use active recall — hear a character, tap the one you heard, and get instant feedback. Work through the Koch-method course, then try a full QSO with a simulated station. KNOWS WHERE YOU NEED WORK A practice heat map highlights the characters you miss most, and the Learn tab recommends the lesson that will help you most right now. TRACK YOUR PROGRESS Keep a daily streak, watch your keying speed climb, and review your accuracy at a glance. Your streak, heat map, speed history, and settings sync across iPhone, iPad, and Mac with iCloud. MADE TO STAY OUT OF THE WAY No ads. No account. No subscription. Just a focused tool for learning and sharpening Morse — whether you are starting from zero or keeping a ham radio skill sharp.
