About this app

Morse Watcher turns your Android phone’s camera and flashlight into a versatile Morse code communication tool — decode incoming optical signals with your camera and transmit messages with your flashlight.

SEND AND RECEIVE
Easily switch between watching and sending. Open the collapsible sender panel to compose and flash a message using your torch, or keep it collapsed to focus on watching and decoding incoming light pulses.

DECODE
Point your camera at any flashing light source — flashlight, LED, signal lamp, or beacon — and Morse Watcher detects the pulses (dash and dots) and translates them into text in real time. Tap the screen to place a detection target directly over your light source. The app auto-calibrates to the sender's speed and timing.

SEND
Type a message or use voice dictation, hit send, and Morse Watcher flashes your flashlight in precisely timed pulses. Adjust transmission speed (WPM) to match any receiver. An optional audio tone plays along with the decoded signal.
