Flash It! allows you to send and receive messages in Morse code using your device's camera and its flash. If you see a Morse signal sent via Flash It! the app will decode the message for you.
No mobile reception is required, you simply need a clear line of sight to whomever you would like to communicate with. Sending and receiving Morse messages is of course free of any charge.
Communicate with neighbors across the street. Use it for distant communication in the outdoors where you have no reception. Drop optical flash signals in an emergency situation or simply have fun.
The app has been tested successfully on Samsung Galaxy S2, Galaxy Ace and HTC Desire. Camera behavior may be device dependent, so please try out the lite version to make sure the app runs properly on your device.
The full version offers an unlimited auto-detection of signals, customizing settings, an SOS-mode, a message history and is ad-free.
