Note that Broadcastify archives recordings. You can download these recordings for later playback. That became very useful when trying to piece together what happened when two local fire departments couldn't find a fire location[1]. However, you do need to pay for a premium account: I don't need to download scanner sessions very often, so I just pay when I need a download.
[1] To be uncharacteristically fair, just about everyone involved screwed up in some manner. Summed together, the result was a mess. The RP (reporting part) was in such a state of panic they she was screaming into her iphone 4 at the 911 dispatcher, rendering her speech unintelligible. She wouldn't stop to listen to the dispatchers instructions. The dispatcher didn't tell her to not yell into the mic, but told her to slow down, which did nothing useful. Meanwhile, the street was on the border between two jurisdictions, both of whom arrived in force, creating a huge traffic jam. There was also a street/road with the same name nearby. The dispatcher guessed which street, and guessed wrong. Plenty of other scrweups, all nicely recorded by Broadcastify.
