Morse Beacon

Type any message and transmit it as Morse code via flashlight, screen flash, tone, or haptics. SOS, HELP, MAYDAY presets and a saveable phrase library included.

Morse Beacon turns your iPhone into a Morse code signaling device. Type any message and transmit it through your flashlight, screen, speaker, or haptic vibration — together or in any combination.

Designed for hikers, sailors, ham radio operators, scouts, teachers, and anyone who needs to signal across a distance.

PRIVACY

Morse Beacon does not collect, transmit, or share any personal data. All settings and saved messages are stored locally on your device. No accounts. No analytics. No ads. No network connection is used.

IMPORTANT — NOT AN EMERGENCY SERVICE

Morse Beacon is a signaling utility. It is NOT a replacement for emergency services. In a real emergency, always contact local emergency services first by calling 911 (US), 112 (EU), 999 (UK), or your country's equivalent. This app should only supplement, never substitute, proper emergency contact methods. Signaling effectiveness depends on weather, line of sight, ambient noise, and whether anyone is watching or listening.

REQUIREMENTS

• iPhone with rear camera flash for flashlight output
• iOS 26 or later
