Almost perfect!

This app is almost perfect! The only thing I wish you could do is listen to non-named talk groups. In my local area several talk groups appear only as numbers and cannot be listened to individual.

App not responsible for local malfunctions

This app isnt responsible for your towns local system having transmission issues or not working at all . You need to speak with the person who has the system setup in your town and maybe donate some money to for their time because they more then likely do it for free.

Bug or glitch

I love this app I use it almost everyday because 1. I’m nosey LOL and 2. Where my grandma lives is in a ghetto neighborhood so I like to keep track of things. However today the apps not working it’s suck on 3Am nothing past it. It’s almost 2Pm where I’m at currently there’s no way calls have not been made in since 3AM. Please fix this I would hate to have to find the next best thing.

My favorite app but

I really wish there was a way to save talk group preferences as a favorites list. I’d even pay for a pro version of the app if it was available!
