### 3/5 — Bug or glitch

*2026-07-26, version 1.1.1*

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.

### 4/5 — Good app

*2026-06-29, version 1.1.1*

Great app. An auto refresh would be fantastic!

### 4/5 — My favorite app but

*2026-06-18, version 1.1.1*

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!

### 3/5 — Good..could be better

*2026-06-02, version 1.1.1*

Overall, very good app. Lots of choices if scanner sorted by area. My one recommendation would be, is add a search feature to the talk groups. Its very difficult to exclude channels you dont want.

### 2/5 — Too many duplicate channels

*2026-05-30, version 1.1.1*

Scanner shows way too many duplicate channels sand cannot find one channel in my area.  Useless app!

### 1/5 — Limited areas

*2026-05-09, version 1.1.1*

Not a single New Mexico station

### 5/5 — Not working

*2026-04-28, version 1.1.1*

It’s not refreshing for today it’s stuck on 12 pm for Sacramento

### 4/5 — Archive Problem

*2026-04-13, version 1.1.1*

Hi, every time I enable the archive feature, select a date and what not and then when I unselect it, it doesn’t change. When you see like the vertical list of the radio logs, it’s still at the archive date and I always have to uninstall the app and reinstall it for it to fix itself. Everything else is perfect though.

### 1/5 — App Not Working

*2026-03-13, version 1.1.1*

Up until last week, 2026-03-02 the app was working fine; however; it’s now been 11 days of no service! When will the issue be fixed?

### 5/5 — OpenMhz

*2025-11-18, version 1.1.1*

Still working.
