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. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | MorseCAT Pro | $4.99 | one-time | ## Version history (last 2 releases) ### 1.0.1 — 2026-09-02 Fixed Bluetooth issues with sound ### 1.0 — 2026-08-21 No release notes. ## More apps by Aspen Ventures, LLC - [ECHOCAT - Ham Radio Remote](https://appshunter.io/ios/app/echocat-ham-radio-remote/id6766321194) - [ScoutCAT: POTA & SOTA Map](https://appshunter.io/ios/app/scoutcat-pota-and-sota-map/id6795701085) All apps by Aspen Ventures, LLC: https://appshunter.io/developer/1479334231 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
