Morse Watcher

Send & receive messages via light. Flash messages with your phone's flashlight while decoding incoming light in real time. Now with audio tone feedback.

Morse Watcher turns your iPhone camera and flashlight into a two-way Morse code tool — send and receive on the same screen, in real time.

SEND AND RECEIVE TOGETHER Open the sender panel to type and flash a message with your torch while the camera keeps decoding incoming light pulses. Collapse the panel any time to focus on watching, or pin it open for live two-way conversations.

DECODE Point your camera at any flashing light — flashlight, LED, or beacon — and Morse Watcher detects the pulses and translates them to text in real time. Tap the screen to place a detection window on your light source. The app auto-calibrates to the sender's timing — works best with dot durations of 100ms or longer (camera-limited at 30 FPS).

SEND Type a message, hit play, and Morse Watcher flashes your torch in precisely timed pulses. Adjust timing to match any receiver. Audio tone feedback plays while the signal is on.
