Morse Code: Text to Light

Morse Code turns text into light with a clean, focused transmitter for iPhone.

Type a message and see its International Morse Code sequence before and while it sends. Use the rear flashlight for visible signaling, or switch to full-screen output when the torch is unavailable or you prefer the display.

Features:

• Live dot-and-dash preview with message progress
• Rear-flashlight and full-screen light output
• Adjustable Morse speed with a device timing estimator
• Pause, resume, stop, replay, and continuous repeat
• One-tap SOS text shortcut (does not contact emergency services)
• Support for letters, numbers, and common punctuation
• Accessible labels, large controls, haptics, and reduced-motion support
• No account, ads, analytics, or cloud backend

Everything you type is converted locally on your device. Messages are not sent to Sarcomere or stored on a remote server.

Flashlight control requires Camera permission because iOS exposes the rear LED through the camera system. Morse Code never takes, saves, inspects, or transmits photos or video. If Camera access is denied, Screen output remains available.

Safety: Do not aim flashing light at eyes, drivers, aircraft, or photosensitive people. Morse Code is a signaling utility, not an emergency service or certified safety device.

Optional support: leave a one-time tip from Settings if you would like to support development. Tips are entirely optional, do not unlock features, and are not a subscription. The App Store shows the price and asks for confirmation before charging.
