HamStudy is not your typical study app. Most study apps focus on practice exams, which is like studying for your math test by trying 20% of the questions on repeat. Study smarter with HamStudy. Instead of taking practice tests with random questions over and over, our intelligent Study Mode tracks your progress as you move through the questions—what you’ve seen, what you haven’t, and where you’re struggling—and focuses your study on the questions you need to see most. Full statistics are provided along the way, giving you insight into how many times you’ve gotten a question right or wrong as well as your overall study progress. Don’t worry, you can still take practice exams whenever you want. You won’t find a better tool to use alongside your favorite learning material. Through collaboration with some of the most recognized names in amateur radio, HamStudy allows you to simply choose from a selection of license manuals, then instantly adapts so you can match your study to the chapters, topics, and sections you’re used to†. Want to study just the questions from chapters 4 and 5? No problem. And when a question trips you up, just tap the Explain button to understand what you missed, review formulas, and read helpful study tips. Features: • HamStudy's intelligent study algorithms work with you to ensure you learn the questions, tracking your progress and adjusting the pace to keep you challenged but not frustrated. • Vetted user-submitted explanations help you avoid the pitfall of just memorizing answers. • Infinite practice exams. Fun fact: it takes around 70 practice exams before you’ll see every Technician question just once. Study more, test less! • Study all current US Amateur Radio question pools: Technician, General, and Amateur Extra. Updates are downloaded automatically, and new pools are always included free when they are revised every four years. • English and Spanish translations included for US Amateur Radio pools. • Includes an ever-growing selection of international question pools, such as Canada, Mexico, New Zealand, and Argentina. • Supports multiple users on the same device, each with independent study history. • Sync your progress across all devices and study online with a free hamstudy.org account. • Share your progress with friends, instructors, or other HamStudy.org users and help each other keep progressing towards that next license exam! HamStudy is proud to be sponsored by Icom. † Disclaimer: HamStudy does not contain the actual instructional material from linked books, but works great with the book sitting on the table next to you!

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.

Verdict

HamStudy.org's advantage is in-app purchases (none vs 1) and chart position (#6 vs unranked). On ads, device support and iOS requirement there is nothing between them.
