Learn Morse code straight by ear — skip the detour of reading dots and dashes. The Koch method gets you there fast.
Morse Trainer teaches you Morse code straight by ear — skipping the detour of reading dots and dashes off a screen entirely. The built-in Koch method has you recognizing every character by sound from day one, with especially fast learning progress.
BEGINNER – LEARN FAST WITH THE KOCH METHOD
You start with just two characters, sent at full target speed right from the first round — no slow ramp-up, no visual reading step in between. Once you recognize them reliably, the next one unlocks automatically. Letters, numbers, and special characters are trained separately, each with its own progress. A simple points display always shows exactly how close you are to the next character. No guesswork, no plateaus — just clear, measurable, fast progress. New and misjudged characters come up more often so they stick sooner. Once every character is unlocked, each level raises your speed — up to 30 WPM.
RECEIVE
You hear real Morse tones, get a short thinking pause to guess, then see and hear the answer. Five modes: single characters, 3-character sets for one minute, abbreviations and Q-groups, Preselection (you pick exactly the characters you want to practice) and Callsigns. Callsigns are randomly generated, realistic callsigns from around the world — with real country prefixes, common countries appearing more often, in 4, 5 or 6 characters. Repeats, speed, thinking pause and letter pause (in seconds) are all yours to set.
SEND
All modes are available for sending too, including Preselection and Callsigns. With an external keyboard (USB or Bluetooth), your iPhone becomes a Morse keyer — two keys as a paddle, including squeeze support for clean iambic keying. The app calls out a character or abbreviation, you send it back, and get instant feedback. "Weak Spots" mode specifically repeats the characters you get wrong most often. In Practice mode, you send freely and the app decodes live. If you'd rather use a real Morse paddle instead of a keyboard, you'll find a build guide for a matching adapter on GitHub: https://github.com/gogogommez/Morse-Adapter
