It is a safety item. Every time there is a weather or related watch, warning or whatever -- it shows up here. All of the information shows up. There are the complete NOAA text, maps, references to additl info, if it exists, anything else relevant. I think I have 20 (+/-) weather apps between the iPad and iPhone. They change from time to time, depending on the app development, seasons, etc. But this app hasnt been deleted yet. The app is especially relevant during severe weather season here in the Midwest for tornadoes, hail, thunderstorms, flooding. Simple and relevant. Good.
