Signal Light for iOS

Note: Your device must have a flash to use this app!This is a handy tool for campers, scouts, boaters, (and spies)!Use it to communicate with distant friends using Morse code, tap out a beat for a human-powered strobe light, or get the attention of rescuers.This app is based on a signal lamp which is a manually-controled shuttered spotlight used on warships to communicate securely while maintaining radio silence.Modern navies still use signal lamps, but now use infrared wavelengths and night vision goggles!Extra fun:Put a paper towel tube on the flash to make a tight spotlight and youve got a line-of-sight communication tool that only you and your partner can see.p.s. SOS is . . . . . .
