CANARY.free is like the proverbial canary in the coal mine, monitoring your world to provide you with advanced warning of impending global disasters.
This free version monitors Near Earth Objects such as asteroids, significant seismic events such as those caused by earthquakes, volcanic eruptions, and nuclear weapons detonations. CANARY.free also monitors virus/bacterial outbreaks, wars, terrorism, piracy on the high seas, Space weather such as Solar flares and X-Ray bursts, as well as North American weather.
CANARY.free has offline survival tips available on your smartphone even if the cellular grid is down, and monitors ammunition prices, gold pricing, and stock pricing (optionally) while the grid is up in case a major price move signals that something big is happening (or impending).
CANARY.free allows you to communicate with, or simply view, the facebook posts of other CANARY.free app owners, if desired.
In addition, this app monitors global breaking news and the U.S. Military's DEFCON status.
If you are a world traveler, a prepper, a survivalist, a soldier of fortune, a diplomat, in the military, a businessman, a hiker, a rock climber, or engage in any pursuit that takes you either away from urban civilization or into global hot zones, then this app could save your life.
