Proved its usefulness
I live in an area prone to tornadic activity and got this app some time ago. After configuring my settings to alert me only to tornado warnings within 10 miles of me, it offers a super early warning system, with a siren that is loud and notable enough that it was able to wake me from a dead sleep last night about 5 minutes BEFORE my county got its own tornado warning, due to the neighboring county being within that 10 mile radius. I highly recommend this app for peace of mind.
