Morse Code Translator & SOS

Turn your iPhone into a real signal light. Flash Morse code from the LED, send a repeating SOS beacon, or hold a steady beam at exactly the brightness you want.

Five modes, one big button.

STEADY
A plain, dependable beam with a brightness slider that runs from a dim night reading light to full output.

SOS
The international distress pattern, keyed correctly and repeating on its own until you stop it.

STROBE
Adjustable from 1 to 20 Hz. Tap the tempo pad in rhythm and the flash locks to the beat of whatever is playing.

SCREEN
Fills the whole display with ivory, amber, ruby, jade, ocean, violet, blackout or daylight white, for when you need colour instead of a beam.

MORSE
Type any message and send it as dots and dashes. The pattern is previewed on screen before it goes out, and the character being keyed is highlighted as it transmits.

FOR PEOPLE WHO ACTUALLY KEY
- Keying speed set in words per minute, from slow enough to learn on up to operator pace
- An audible sidetone so you hear every dot and dash
- Haptic dots and dashes you can feel in the dark or in a quiet room
- The screen washes in step with the LED, so the signal stays readable with the phone face up on a table

LEARN MORSE, BUILT IN
- The full ITU chart of letters and digits
- Flashcards with a streak counter
- A decode drill that shows a pattern and asks you to name the character, with a running score

PRESETS
Save any combination of mode, brightness, speed and colour as a named preset and bring it back with one tap. Rename it, delete it, or share it as a link. Opening that link on another iPhone drops the preset straight into their library.

The app asks for camera access for one reason only: that is the permission iOS requires to drive the flashlight LED. Nothing is recorded, and there is no photo or video capture anywhere in the app.

Beam modes need an iPhone with an LED flash. Screen mode works on any device.
