Morse.

Say it across the dark. Morse turns a few words into flashes of light. Type a message, press Broadcast, and your iPhone's flashlight sends it in International Morse code while a paper tape punches each dot and dash as it goes. Point another phone's camera at the light, and Morse reads it back into text. SEND • Flashlight, screen light, sound and vibration, together or one at a time • Three named speeds: Learner (5 WPM), Standard (8 WPM) and Brisk (12 WPM) • Full International Morse: letters, numbers and punctuation, with the standard timing • Characters with no Morse sign are flagged on the tape, never silently dropped • A built-in translator converts text to dots and dashes as you type RECEIVE • Aim the rear camera at a flashing light. No pairing and no agreed speed: Morse works out the pace from the flashes themselves • A live transcript fills in as letters decode, with a copy button • A meter tells you whether it is hearing nothing, hearing light, or seeing light that is not Morse • A received log keeps your last 100 messages on your device • Works best with another phone running Morse. A hand-held flashlight keyed by a person is best-effort MADE FOR EVERYDAY USE • The screen stays on while a message is sending or the camera is listening • Light, dark, high-contrast and automatic themes, with a choice of accent colors • Choose the screen-light color for broadcasts PRIVATE BY DESIGN Nothing you type and nothing the camera sees leaves your iPhone. Camera frames are reduced to brightness samples in memory, never recorded or uploaded. There is no account, no advertising and no tracking. The camera closes the moment you stop. A NOTE ON FLASHING LIGHT Morse flashes a light on purpose. If you are photosensitive, stay on the Learner speed and do not watch the light directly. A caution is shown before your first broadcast.
