Morse Code Trainer, CW Decoder vs Morse Code

Morse code becomes far more useful when you can do more than look it up. MORSE gives you one clean workspace to translate a message, hear or send a signal, build real listening and keying skills, and keep the tools you need close at hand. Translate and send right away • Convert text to Morse code and Morse code back to text • Work with seven writing and code systems: International Morse, Chinese telegraph code, Japanese, Korean, Russian, Greek and Arabic • Send signals with sound, haptics, the flashlight or screen flashes • Choose playback speed and carrier tone, or start with ready-to-use common phrases Learn to hear it—not just read it • Follow 174 structured lessons across 29 units and six activity types • Build skills in Koch order through recognition, listening, comparison, sending, applied practice and challenges • Progress from characters and numbers to punctuation, prosigns, Q codes, callsigns and complete QSOs • Take a free 15-question daily test shaped by your current progress and previously learned weak points • Track accuracy, best scores, course progress and practice streaks • Pro unlocks the remaining 150 lessons, focused listening, Head Copy and weakness drills, plus full WPM, tone and Farnsworth controls Read real signals when you need to • See a provisional dot-dash and text preview while recording; after you stop, MORSE analyzes the full recording and produces a corrected result • Import audio, video or images containing Morse signals • Let MORSE analyze carrier tone and timing, with status and confidence feedback • Core media analysis runs on your device instead of sending signal content to a cloud recognition service Communicate, save and share • Enter dots and dashes with a Morse key and see the decoded text as you type • Exchange Morse messages directly with another nearby device; Pro adds optional 4-digit PIN content protection • Keep history and favorites, then reopen an item to continue editing • Export text and Morse signal cards for free; Pro adds WAV audio export • Import or export a local backup of your training progress Start free. Unlock Pro once. MORSE is free to download. Core text conversion is unlimited, and basic signal output, character references, daily tests, the first 24 lessons and nearby communication without a PIN are free to use. Microphone, audio, video and image recognition share one successful free experience. There are no ads, subscriptions or automatic renewals. MORSE PRO is a one-time non-consumable purchase that permanently unlocks Pro features. Your localized price is shown by the App Store, and previous purchases can be restored. New ways to practice Practice receiving Morse with keyboard answers and character-by-character feedback in Pro. Try straight-key input for free to work on the timing of dots and dashes.

Most Morse code apps hand you a table of 26 patterns and wish you luck. Morse Map hands you the structure underneath the table. Morse code isn't a list. It's a decision tree. From any point, a dot takes one branch and a dash takes the other. E is one dot from the start. A is E plus a dash. R is A plus a dot. Nobody memorises 26 unrelated patterns — they learn one map and walk it. This app draws that map, and lights up where you are on it. SEE THE CODE, DON'T MEMORISE IT Two ideas make the diagram readable at a glance. Every node is drawn as the symbol that reaches it — a circle for a dot, a long bar for a dash. Read the shapes along a path and you have just read the code. No legend. No lookup. And depth runs left to right, so a path reads in the same direction as time. The route to J is dot dash dash dash, which is exactly what J sounds like. The tree is the waveform. Key a dot and a packet of light travels the trace into the next node. The path stays lit while the rest of the map dims, and the two branches you could take next are marked — so you are always looking at the one decision in front of you, not the whole alphabet. DECODE Tap separate dot and dash keys, or switch to a real straight key where the length of your press decides the symbol, with a live indicator showing when you cross into dash territory. A pause finishes the character, with a ring closing around the live node so the timing is visible rather than guessed. Prefer to be deliberate? Turn it off and press Enter yourself. Tap any node to jump there and hear it — exploring is free, and nothing is typed until you ask. Undo works one element at a time, which is what you need most when you are new. SEND — INCLUDING BY LIGHT Type a message and transmit it as genuine Morse, with correct element lengths and correct gaps, on four channels at once: • Sound — a real keyed sidetone. • Light — flash the message out of your camera's torch, exactly the way a signal lamp works. Point it across a room, a field, or a valley and it is a working Morse transmitter. • Haptics — feel each element at its true length. • The map — watch the tree walk your message as it goes. Copy the encoded string out to share it as text. TRAIN Practice, so the map eventually stops being something you look at. • The Koch method — start with two characters at full speed and earn the next one at 90% accuracy. This is the method that works. Learning slowly and speeding up later just means un-learning a rhythm. • Listen: hear a character, name it. • Key it: see a character, send it on the tree. • Per-character mastery, experience levels and daily streaks. CODEX All 62 characters — 26 letters, 10 numbers, 18 punctuation marks and 8 procedural signals — each with its code, its spoken rhythm (di-dah-dah-dah), where it sits in the tree, and how well you know it. BUILT PROPERLY • Real PARIS-standard timing, adjustable from 5 to 30 wpm. • Farnsworth spacing: keep characters crisp while the gaps stretch. • A true gated sidetone oscillator with ramped edges, not clicky samples — tune it from 300 to 1000 Hz. • Core Haptics, so a dash feels three times as long as a dot. • Mixes with your music instead of silencing it. • VoiceOver support, including a live spoken description of your path through the tree. Reduce Motion respected. NO ACCOUNT. NO INTERNET. NO DATA. There is no networking in this app at all. No sign-up, no ads, no analytics, no tracking, no third-party code. Your settings and progress live on your device and go nowhere. It works the same in a basement, on a plane, or off-grid — which, given the subject, felt like the point. Whether you are studying for an amateur radio licence, learning CW for the love of it, or you just want to know what the flashing light in the film actually said — start with the map.
