Morse Flashing

Send Morse code as light between two iPhones — and learn it for real with the Koch course and Echo Trainer. English and Arabic, fully offline.

FlashMorse turns two iPhones into optical telegraphs. Type a message on one phone and it flashes out through the torch, the screen, or as sound — point the other phone's camera (or microphone) at it and watch the message decode live. No internet, no accounts, completely offline.

The only Morse app with full Arabic support: the authentic 29-letter Arabic telegraph code alongside International Morse, with a fully right-to-left Arabic interface.

TRANSMIT & RECEIVE • Torch, full-screen flash, or 750 Hz sound transmission • Real-time camera decoding with auto speed calibration • Microphone decoding of Morse tones • Pinch-to-zoom, live signal timeline, haptic dot/dash playback • Works with other Morse apps and manual flashlights too

LEARN FOR REAL • Koch course: characters at full speed, one lesson at a time (the method serious operators use) — including the first-ever Arabic Morse course • Echo Trainer: hear a character, key it back, instant feedback • Morse Machine: endless adaptive practice • Tap-key practice pad, quizzes, per-letter stats, daily streaks

ALWAYS FREE IN AN EMERGENCY • SOS from Siri, the Action Button, or a Lock Screen widget • SOS loops until you stop it — never behind a paywall

TRANSLATE & REFERENCE • Instant text ↔ Morse translator with sound and flash playback • Complete reference chart for both alphabets

FlashMorse Pro (one-time purchase, no subscription): unlimited message length, 4–20 WPM speed control, auto-repeat, saved messages, received-message history, the full Koch course, Echo Trainer, and detailed stats.

Your messages never leave your phone. FlashMorse collects no data at all.
