Morse ICR vs MorsePCB

Why Morse ICR? Because learning Morse code is about listening, not just memorizing. Morse ICR helps you develop the ability to recognize Morse code by sound, reinforcing your skills through real-time audio and interactive practice. Whether you’re a beginner or a seasoned enthusiast, this app offers a comprehensive approach to Morse code mastery. Key Features: • Interactive Keyboard Input: Practice your Morse code by typing on a keyboard specifically designed for learning. • Visual Highlights: See which keys to press with visual cues that guide your learning. • Progressive Learning System: New characters are introduced gradually, helping you build confidence step-by-step. • Customizable Practice Sessions: Tailor the number of characters, practice length, and speed for the perfect training session. • Streak Tracking & Records: Stay motivated by tracking your longest streak of consecutive correct answers! • Comprehensive Stats: Track your total correct answers, practice time, and progress across sessions. • Adaptive Difficulty: Struggling with a character? After three consecutive mistakes, the app highlights that character to reinforce learning. • Full Morse Code Support: Practice with letters, numbers, and special characters in Morse code. • Customizable Settings: Adjust settings like WPM speed and more to fit your needs. • Keyboard & Device Compatibility: Supports physical bluetooth keyboard input. • Background Tracking: Keep your progress saved even when the app goes inactive.

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.
