The Best there is

The ONLY Scanner app Ive found that allows the scanning of four feeds at the same time. And you can store 4 separate sets (banks) of four feeds each. Unless you need an app that records a scanner feed, this is the one to spend money on. Its regularly updated with the latest available feeds (NONE of these scanner apps supply their source feeds - so no complaints, please, that your community or desired feed isnt there - the software developer has no control over this). You can even manually add a feed url on the rare occasion you find one you want thats not available on this scanner - I did once, but only a few days later it was included in of the available updated feeds on the list. Extremely pleased with this app.
