Great at some things, not at others
I live in Kansas and this app is not the best for the super cell storms we get. The radar is not really helpful and I use much more advanced weather radar apps for this. However, even in the best radar apps I have the weather service alerts are over a minute behind weather underground. This app can alert me to a tornado even 2 minutes before the sirens go off. Its worth downloading just for this speed alone. Minutes=safety in Kansas.
