DotDotDoit: Morse Code

DotDotDoit turns your phone into a complete Morse-code studio — and it works
entirely offline, with no accounts, no ads, and no tracking.

SEND ANYTHING
• Type a message and play it as beeps, torch flashes, a screen strobe, or vibration.
• Tap it out yourself on the built-in Morse key.
• One-tap SOS: sound + flash + haptic together.
• Repeat a message on a timer (e.g. SOS every 10 seconds).
• Save your own quick phrases, or use the built-in ones.

RECEIVE & DECODE
• Point the mic at beeps and watch it transcribe in real time, with a live signal waterfall.
• Aim the camera at a blinking light to decode it.
• Read dots and dashes straight from a photo.
• Paste a Morse string to convert it back to text.

LEARN & PRACTICE
• A full, searchable reference table for letters, digits, punctuation and prosigns.
• A gamified practice trainer that teaches the alphabet the proven Koch way —
hear a letter, pick it, build streaks, and unlock new letters as you improve.

SHARE IT YOUR WAY
• Export your message as a shareable image card, a phone wallpaper ("your name
in Morse"), or an animated GIF.
• Share as text or as a real .wav audio clip.

PRIVATE BY DESIGN
• 100% offline. Your audio, camera and messages never leave your device.
• No accounts, no ads, no analytics.

Available in 14 languages: English, Portuguese (PT & BR), Spanish, French,
German, Italian, Turkish, Russian, Ukrainian, Arabic, Hindi, Chinese
(Simplified) and Japanese.

For fun and learning — please don't rely on it as your only way to signal in an
emergency.
