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.
