The difference between this app and everything else is that it consolidates information on an easy to read page and you aren't redirected to a web based page explaining all the rules. And, it's a single countrywide app. Sure, I still have my state based alert systems but, when I'm tired, I can just find my location and I can see in simple terminology what rules are in place. My only quibble (for now) is scrolling down is a bit tricky.
