### 1/5 — We

*2025-11-19, version 2.15*

My phone calls double upon adding this app

### 1/5 — Is this a joke?

*2025-09-13, version 2.15*

Can’t even move past the text verification. How effective can it be if it fails at such a simple level?

### 2/5 — Blocks contacts

*2025-09-07, version 2.15*

We all want to be protected from the calls we don’t want but when you choose to allow contacts, it shouldn’t block those calls. My own children couldn’t call me until I added them manually. I also am never notified anyone is calling. It just bypasses me and blocks EVERYTHING. I have repeatedly tried to change the settings but they all are where they should be. If I never wanted to ever receive ANY calls, that would be fine but I’d like to know when ppl are calling so I can decide to accept or decline a call.

### 1/5 — Wish it worked

*2025-09-04, version 2.15*

Installed app on my us cellular iphone 15.  Go through setup process and get to point it is supposed to send you a code and it never sends it.  Tried multiple times and on different days with no code sent.  Very disappointing

### 1/5 — All but useless

*2025-08-02, version 2.15*

Great, it notifies you that there’s a spam/spoof call, but it does do squat with it.  Heck, I KNOW it’s a spam call!  What ai need the app to do is straight up block it!  Worthless.

### 1/5 — Darbo

*2025-04-17, version 2.15*

I was receiving 10-15 spam calls everyday- so I contacted US Cellular and they said I qualified not only for the basic plan, but the premium plan for FREE!! So I downloaded it and set my phone and wow- now I get 15-25 spam calls everyday and my co-worker's calls got blocked! Gotta love it. What a P.O.S.

### 2/5 — Spam calls

*2025-04-10, version 2.15*

I still get spam calls… all the time…. And the app blocks my legit calls from people saved in my contacts… 

The app use to work so well.

### 1/5 — Last 3 days

*2025-03-14, version 2.15*

App worked for a few days and my amount of spam is back to the same amount. Doesn't block suspected spam.

### 3/5 — Updates

*2025-02-24, version 2.15*

I like using the Call Guardian but I keep getting messages asking me to update because the spam numbers may be outdated, and when I go to do so there’s no update to do. 
It’s a little frustrating.

### 1/5 — Pointless

*2024-11-09, version 2.15*

This  wasteful app stops nothing
