MorsePhone turns an Android phone into a four-mode Morse code station that works in complete offline / airplane mode. Four tabs: Send (speaker, 700 Hz keyed tone), Listen (microphone decoding), Flash (torch key), Watch (camera light-pulse decoder). Two phones can exchange messages at night line-of-sight via flashlight, or across a quiet room over audio. Also works as a Morse training tool for radio operators.

Capabilities

Send mode — type text, plays as 700 Hz keyed Morse tone

Flash mode — keys the back-camera torch for visual Morse
Watch mode — camera watches a flashing light, decodes to text
