Signals

Signals is a simple app. You choose a color and your screen start blinking. Let your friends find you in live concerts, theaters, while camping outdoor. Alert drivers while you are on the side of the road, repairing your car, your bike or just walking. Decide a shared code for each color, and communicate with your group without an internet connection, gps working or phone reception. You can also use it with the white color, and it's an useful basic flashlight. Not too bad for a such simple app, isn't it?!
