### 1/5 — No good

*2026-08-23, version 24.7.55*

This app doesn’t work-spam calls aren’t blocked-waste of money

### 1/5 — More spam calls

*2026-08-23, version 24.7.55*

On a free trial, you will literally get more spam calls. Horrible. No good.

### 1/5 — Was going to renew but..

*2026-08-21, version 24.7.55*

I had to cancel a couple months ago because my financial situation was getting pretty tight and I couldn't afford the $5.99/mo for this service. I come back to renew because the spam calls are ramping up again and my budget opened up to where I could afford it again and now the lowest subscription available for me is $10.99/mo. Um? No. I had to quit at $5.99 due to hard times. And now that I can afford that 5.99 tag it's telling me it's increased? Hell no. I'll just block numbers when they call. I don't care if they're being spoofed or not. I don't ever answer my phone anyway and I only know like 2 people. Bring your rates back down or keep losing customers. Everyone is struggling in this terrible economy. Being greedy isn't going to make people want your service.

### 1/5 — Calls

*2026-08-21, version 24.7.55*

The call continue to go through.

### 1/5 — Quality has gone downwards

*2026-08-21, version 24.7.55*

This use to be a great app when it came out. Now iPhones basically automatically screen your calls. The price was 5.99. Now it’s jumping to 10.99. That’s just greed. I’ll be canceling and moving onto a new spam blocker.

### 5/5 — Like it very much

*2026-08-20, version 24.7.55*

Finally got something that work for me thank you

### 3/5 — Good concept

*2026-08-19, version 24.7.55*

This app successfully screens spam callers and wastes their time. It also gives you a lovely recording of the spam callers talking to your robot. Unfortunately, many spam bot centers now use AI bots that look for specific responses fo avoid wasting time (“can you answer yes or no?”), which RoboKiller’s recordings can’t effectively counter.
Still, I appreciate not having my phone ring throughout the day, and I HUGELY appreciate them getting my information off the databases these spam callers use. That alone has decreased the number of spam bots I get.
If it were cheaper, 5*. Because they charge $100+/yr, 3* until they can figure out a RoboAIKiller to get the AI bots to transfer to a human.

### 5/5 — Outstanding

*2026-08-19, version 24.7.55*

Returns peace and tranquility to the ownership of my cell phone. What a joy. It cancels so many unwanted calls. Best in SPAM BLOCKING!

### 1/5 — Bruh

*2026-08-18, version 24.7.55*

It ain’t blocking the calls that I’m getting

### 5/5 — Works like a dream

*2026-08-18, version 24.7.55*

Thank goodness
