Morse Trainer – learn CW

You do not learn Morse by watching. You learn it by listening and by keying. That is what this app is built for: a course that grows with you, and an honest verdict on your own fist.

LEARN TO COPY
• 40 lessons following the Koch method: start with two characters, add the next one only once you copy reliably
• Full character speed from the first lesson, only the gaps are stretched (Farnsworth) – your ear learns the sound of a character instead of counting dots
• Feedback after every group, not only at the end
• Every character you miss is replayed on its own straight away, shown large while you hear it
• "Practice weak spots" draws more often on the characters you personally confuse
• Speed and pitch freely adjustable, 5 to 30 WPM

LEARN TO KEY
• Straight key on the display: how long you hold decides dit or dah
• Paddle with an automatic keyer, mode A or Curtis B, sides swappable
• Or your own key on a tone generator – the app listens through the microphone
• Or a key connected as a keyboard adapter, over Bluetooth as well
• The decoder is tolerant: it measures YOUR speed and follows you as you get faster
• A quality verdict per exercise, split into dits, dahs and gaps – plus one sentence telling you what to change
• "Listen to your keying and the ideal": first your own characters, then the same ones in a clean rhythm

ON AIR
• The band as a waterfall, heard through the microphone at your radio's speaker
• Several stations at once: every detected signal gets its own decoder, with frequency and estimated speed
• A log of what you received and sent, ready to share as text
• Send through the speaker: free text and macros for CQ, your call sign, 73 and K

WHY THIS APP
• No account, no sign-in, no connection to the internet – the app does not even hold the permission for it
• The microphone serves only the on-air mode and the external key; audio is analysed on the device and discarded immediately
• Your course progress stays on your device
• Plain and fast, on older devices too

NOTE
Made for radio amateurs and for anyone learning Morse from scratch. Transmitting on an amateur band requires a valid licence – this app produces tones, not a radio signal. The app is a tool and does not replace professional advice; check results before you rely on them.
