Send text as Morse code with the flashlight and read it back with the camera, optionally encrypted with a master password. One phone flashes, another one points its camera at the light and turns the pulses back into text. It also reads any other blinking light: a lamp, a screen, a torch in the distance. • Send: type, pick the speed, flash. Repeat in a loop so the receiver has time to get settled. • Receive: aim and press Start. Pinch to zoom on distant lights. Each repeat lands on its own line, and the received text can be edited by hand. • Encrypt / Decrypt: AES-256 with a master password, in a compact format of letters and digits made for Morse: "HOLA MUNDO" becomes 26 characters. The receiver follows only what blinks, so a bright screen next to the lamp does not blind it. It measures the sender's speed by itself, tolerates a hand holding the phone and pauses while the phone moves. No network permission: nothing leaves the phone except light. Nothing is stored. Sending needs a phone with a flashlight; receiving needs a camera.
