## Description

Learn Morse code the way high-speed operators actually hear it: as sounds, not dots and dashes.

MorseCAT is an Instant Character Recognition (ICR) trainer. Every character is sent at real speed from day one — you never count elements, you learn the sound. Then you answer the way an operator would: key it back.

LEARNING IS FREE. FOREVER.
• The full guided path — every letter, number, and prosign, in the proven CW Academy order
• Listen & Learn — hear each character introduced as pure sound
• Listen & Say — say the character out loud and MorseCAT grades you by ear
• Free Practice — your speed, your character set, whenever
• Word Patterns and weekly LICW class groups — drill exactly what your class covers
• Progress that means something: a per-character mastery heatmap, recognition-time tracking, a copy-ceiling benchmark, streaks, and a proficiency rank

ANSWER LIKE AN OPERATOR
Hear a character, key it back. Use the on-screen straight key, the touch paddle, or plug in real hardware — Bluetooth MIDI keyers and paddles (TinyMIDI, HaliKey, VBand-style interfaces) take over automatically the moment they connect. Motor memory in, guesswork out.

REAL SPEED, HONEST NUMBERS
Characters always sound at your character speed (default 32 wpm, floor 25) — fast enough that there's no time to count elements, which is the whole point. Difficulty comes from closing the gaps, Farnsworth-style, never from slowing the code down. MorseCAT measures your time-to-recognize on every single character, so you always know which ones are instant and which ones still make you think.

MORSECAT PRO — ONE PURCHASE, YOURS FOREVER
A single one-time unlock (no subscription, ever) opens the arcade and the airwaves:
• Key Invaders — read the falling words, shoot them by keying them
• Ice Dash — an arcade sprint for your sending hand
• The full QSO simulator — realistic contest and club exchanges: SST, POTA hunting, CWT, SKCC, and LICW scenarios, with band noise and fading if you want it
• Advanced push drills — the Miss Drill and Send Sprint
Code Invaders, single-caller QSOs (5 a day), and every learning tool stay free — and the whole arcade opens free for ten minutes every day, so you can try it before you decide.

NO NONSENSE
• No account. No ads. No tracking.
• Works offline — practice on a plane, in a park, anywhere
• Your progress lives on your phone, nowhere else

Whether you're prepping for your first POTA hunt, keeping up with your LICW class, or chasing 40 wpm head-copy, MorseCAT meets your ear where it is and pushes it — one instantly-recognized character at a time.

73, and happy keying.
