HamStudy.org vs MorsePCB

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!

Experience the elegance of Nordic modern design fused with the timeless craft of amateur radio in Morse PCB—a comprehensive, next-generation Morse code (CW) suite. Equipped with an interactive binary-tree circuit board visualizer, LEDs light up in real time along electrical traces to trace every dit and dah. Whether you are practicing Morse code individually or exchanging secret messages between two phones using pure sound, Morse PCB offers an unmatched experience. --------------------------------------------- ◆ Secret Morse Chat Between 2 iPhones --------------------------------------------- No internet, Wi-Fi, or Bluetooth pairing required! Simply install the app on two devices to enjoy spy-thriller-style acoustic communication: • Device A (TX / Transmit Mode): Type your message and hit PLAY to broadcast Morse code audio through the speaker. • Device B (RX / Receive Mode): Place the microphone nearby, and the built-in DSP engine instantly detects the audio tones, decoding them into text on screen in real time! Experience the wonder of messages traveling through the air as sound—perfect for friends, family games, secret codes, and ham radio simulations. --------------------------------------------- ◆ Core Features --------------------------------------------- [1. BOARD / Interactive Practice Mode] • Intuitive Binary-Tree LED Card: Tap any letter or number node on the circuit board to understand Morse code hierarchy visually. • Telegraph Key Simulator: Tap or hold the telegraph key button (short press for Dit / long press for Dah). Practice manual keying with real-time automatic decoding and speed tracking. [2. TX / Transmit, Playback & MP3 Export] • Instant Text-to-Morse Conversion: Type English or Romaji to instantly generate accurate Morse code. • LED Synchronized Playback: Hear precise audio sidetones while the circuit board LEDs trace the transmission path in real time. • Customizable Sound: Fine-tune SPEED (5 to 35 WPM) and PITCH (400 to 1000 Hz) via intuitive sliders. • MP3 Export & Sharing: Export your Morse code transmissions as high-quality MP3 audio files to share with friends or students. [3. RX / Acoustic Reception & DSP Decoding] • Real-Time Microphone DSP Analysis: Powered by an advanced Goertzel algorithm filter to detect Morse audio from ambient sound and decode it into clear text. • Integrated Signal Detector: Real-time tone strength (SNR) meter, squelch sensitivity, and target frequency controls combined into a sleek single panel. • Audio File Decoding: Import recorded sound files (WAV, MP3, etc.) for high-precision batch decoding. [4. CUSTOMIZE / Nordic Modern Themes & Wallpapers] • Nordic Modern Aesthetics: Clean, distraction-free color palettes inspired by Scandinavian polar nights, fjords, and evergreen forests. • Custom Wallpapers: Personalize the background of the circuit card with your favorite photos and adjust transparency. --------------------------------------------- ◆ In-App Purchases & Advertisements --------------------------------------------- All core features of this app are available for free. A banner advertisement is displayed at the bottom of the screen in the free version. An optional Premium In-App Purchase is available to permanently remove all advertisements for an uninterrupted experience. --------------------------------------------- ◆ Privacy & Security --------------------------------------------- Microphone audio used by the RX feature is processed locally and in real time using on-device digital signal processing (DSP). Audio data is never recorded to persistent storage, nor is it ever sent to any external server. The app functions completely offline with full privacy.
