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!
