// SCORE BREAKDOWN
Highly specialized real-time Morse decoder with impressive camera-based detection and dual encode/decode; niche but executed with remarkable polish and utility.
// ABOUT
Morse Watcher turns your iPhone camera into a real-time Morse code decoder — and your flashlight into a Morse code transmitter. DECODE MORSE FROM ANY LIGHT SOURCE Point your camera at any flashing light — a flashlight, LED, beacon, or screen — and Morse Watcher automatically detects the pulses, converts them to dots and dashes, and translates them into readable text in real time. Tap anywhere on the live camera feed to place a Region of Interest (ROI) precisely on your light source. The app processes only that area at ~30 FPS using efficient luminance analysis, so detection is fast and battery-friendly. SMART AUTO-CALIBRATION Morse Watcher's calibration engine observes incoming signals and automatically learns timing boundaries for dots, dashes, letter gaps, and word gaps. It adapts to any sender speed or style — no manual tuning required. SEND MORSE WITH YOUR FLASHLIGHT Switch to Sender mode, type any message, and Morse Watcher flashes your device's torch in precisely timed pulses. Adjust the dot unit duration and gap multipliers to match any receiver's expectations. Repeat your message up to 10 times for reliable communication. KEY FEATURES • Real-time Morse decoding from camera — works fully offline • Tap-to-place Region of Interest for precise light targeting • Auto-calibration adapts to any Morse speed automatically • Full text decoding: A–Z, 0–9, and punctuation marks • Morse Sender: type text and transmit via torch/flashlight • Telephoto lens support for detecting distant light sources • Optical zoom toggle on multi-lens iPhones (iPhone 13 Pro+) • Adjustable dot duration, dash and gap multipliers • Debug overlay with live FPS and luminance readout • All settings saved between sessions • Light and dark mode support • No internet, no accounts, no subscriptions IDEAL FOR • Ham radio operators and CW enthusiasts • Scouts, survivalists, and emergency preparedness • Morse code learners and students • Puzzle, cipher, and escape room enthusiasts • Teachers demonstrating communication fundamentals HOW TO USE 1. Grant camera permission when prompted 2. Point your camera at a flashing Morse code light source 3. Tap the light on screen to place the detection window 4. The app calibrates automatically — decoded text appears in real time 5. To send: tap the transmit icon, type your message, and press Send Morse Watcher requires a rear camera.
