MorseLight - Morse with Flash

MorseLight turns your phone's flashlight into a Morse code transmitter and its camera into a receiver. Signal a friend across a field, at a campsite, or anywhere without a network: no internet needed.

SEND

• Type a message and send it with the flashlight, watching each dot and dash light up as it goes

• Tap out Morse by hand: hold the torch button to key it yourself

• One-tap SOS and Signal

• Speed from 1 to 10 words per minute, with standard ITU timing

• Optional sidetone, loop transmission and keep-screen-awake

RECEIVE

• Decode a flashing light with your camera: point it, calibrate once, then read

• Or tap along with the light and let the app decode it

• An adaptive decoder works out the sender's speed by itself, so you don't need to agree one in advance

LEARN

• Decoding drill: copy a message flashed on screen

• Sending drill: key letters and words, with your progress saved

• A searchable chart of every letter and number

PRIVACY

• Ad-free

• The flashlight needs no special permission, and the camera is only requested when you open camera decoding

• Works without an internet connection
