You can send and receive message using smart phone's flash light and camera with this app.
It could help you to communicate with others where mobile phone signal is off line due to disaster or other reason.
It converts text message into Morse code and send them as series of flash light or LCD display's on-off , It also receives Morse code using camera and interprets them into alphabet.
Recent disaster in Japan motivated me to make this application.
The main purpose of this application is helping people who meet with disaster to send SOS message.
