### 1/5 — Bad

*2026-08-02, version v13.23*

Requires a phone number to sign up to get a phone number lol

### 1/5 — Poor staff

*2026-07-28, version v13.23*

Got blocked my a staff member for simply using the app, wouldn’t recommend this app to anyone.

### 1/5 — Poor communication

*2026-07-28, version v13.22.1*

I was using the app as well as several of my team members, yes we use it to call people, and I then was blocked with no warning, I woke up this morning with my account blocked which my payment was charged 3 days ago funny enough… you’re not allowed to be unblocked from the app, the support people say “sorry, that’s all I can do” that’s the most robotic answer they could’ve given me.

### 4/5 — Update Glitch

*2026-07-25, version v13.22.1*

Today’s update broke it! (iPhone 17)

### 1/5 — Poor Quality

*2026-07-23, version v13.22*

“This is the most horrible phone service app out there. They’re so worried about their appearance? They should be more worried about function. Every survey is about appearance. My messages don’t go through to people, almost weekly. I don’t get notifications for messages, so often I’ll open the app to send something out and have messages waiting. YOU MAKE ME LOOK BAD. I am a doctor utilizing an app so I don’t have to carry two phones while raising a family and it has not only lost me business, it has failed me in showing up for my clients and operating a professional establishment. Their “support” has never helped me either but has always just pushed off the problem. I’d only recommend this app to someone looking for a CHEAP phone line to let their business FAIL.”

### 3/5 — DEVELOPER PLEASE RESPOND

*2026-07-16, version v13.22*

I loved this app to death. It worked great and did everything I needed it to do amazingly. Yet one day I was randomly banned and cut off from the app now when I try to log in I just get an error code and have no idea why. Please help!

### 3/5 — Overpriced

*2026-07-14, version v13.21.1*

Not worth the money

### 1/5 — Restricted account for no reason

*2026-06-30, version v13.20*

Save your time and money - don’t use this app!!! Restricted my account I was using for business because of zero reason and support said they can’t help. Horrible company

### 2/5 — Has big flaws

*2026-06-27, version v13.20*

Two biggest flaws: #1. You can’t save names of contacts in the app only.  #2. When someone’s calls me, my phone doesn’t ring no matter what settings I set. I only see missed calls and have to call them back. When I do, the app uses a stranger number to make the call.

### 1/5 — Trash

*2026-06-17, version v13.20*

Doesn’t let me make my account so what’s the point
