Morse Watcher

Decode & Send Morse via Phone

Only for iPhone

$99.99 · Designed for iPhone

iPhone

Decode flashing light into Morse code in real time — or transmit messages via your iPhone flashlight. Works fully offline. 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.
