I wonder if the "Siren" that we saw in the "Uniden New Scanner Launch" (
Uniden New Scanner Launch - YouTube) video was an artist rendering, and there really was no app at that time. Either way, any app developer for Android or iOS who is worth the money they're being paid should be able to pull it off.
Heck look at the apps coming out of the woodwork, like the FreeSCAN app that is being sold for $2 for example.
Either way, THAT app is what pushed me to buy the scanner. I find it a little disheartening that enough time has now past to where I (we) can't return the scanner for a refund and the app STILL not available.
I've been more than fair, and don't think I've been treated as such.
All in good fun my friend.
I'm hoping the app is as good as it was hyped, otherwise I'm sure a lot of us will be upset.
