Update: I wrote the developer and there have been no changes in how this app no longer works. He has not fixed this app for my state. I mentioned in the email something I did not mention here and that is that this app does not work on my Air 1 running iOS 10.3 nor my Air 2 running iOS 9.3.5. I really do not like to write reviews at this point, but the day I decided to do so was because my other weather apps showed a tornado alert. I once counted on this app to deliver radio updates for safety for all the millions of people who live here.
I guess many of us will have to find another app. Too bad. I know that developers can now respond within a review, and I challenge him to fix this app or to say that he no longer supports this app.
In case people have missed the news that many, many apps will not work unless they are updated for iOS 11, I warn you not to buy apps that have not yet been updated for iOS 10 at the very least. Apple is now, thankfully, removing many old apps from the store. If you are running iOS 10, you can find which apps that are on your device will not run unless updated.
From the middle of June: I bought this eons ago for iPad 1, and while many people did not have coverage, we did. Now only 2 of the stations work. Sadly this does not include the capital nor any of the major cities. Very disappointed as weather can change rapidly here.
