Morse Watcher

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.
