A simple device that beeps and blinks. Set to warn all members of your faith about an upcoming disaster only your religious leaders have the button to press it.
Sold with a control panel it is activated only when two accredited leaders dial in with the Global Warning app.
The Global Warning website shows you all the warnings being issued.
Good for religions where the faithful do not use smartphones. For others, the Global Warning foundation has an app.
The advanced version can also send a short message with details about the warning.-- pashute, Nov 14 2016 I'm sensing a pattern here.-- st3f, Nov 15 2016 Quite useful for knowing when the world is about to end. I don't subscribe but I've always wanted to know.-- whatrock, Nov 15 2016 random, halfbakery
