I like both
As already stated, there are reasons why a scanner is better. The app has too many limitations, but in my case I have found two situations where I use it. First, there are times when I miss my home town. I like to listen to what is going on, but distance is a problem. The app is handy for that. A one or two minute delay doesn't really matter . I have also found the app useful when I want to listen in on disaster response for other areas in the U.S. One example would be the tornadoes that hit Alabama. I have unlimited data on my phone, and I don't listen that much, so I don't have issues with useage. The limitation is that a link has to be provided, and as in all cases, there is a delay. When at home, I use this website to listen in. When away from my computer, I use the app. It works for me.
