And for those unexpected surprise tornados, the app keeps the mic open so it can detect that "incoming train" sound and still give you 3.7 nanoseconds warning. Included with the app is a leash to strap the phone to your wrist in case it gets rough and things start flying around in the wind.

The app sounds like a weather radio for your phone. Not a bad idea for some people/areas I guess. But I have found around here that alerting weather radios are a horrible annoyance, they go off for every little thing, sometimes counties away.
