### 2/5 — Doesn’t block any calls

*2026-07-10, version 4.0.0*

Their database of spam numbers is pretty good. I like being able to look up a telephone number to see if it’s a telemarketer or phishing. However, it hasn’t blocked any calls in a long time.

### 1/5 — Does NOT WORK

*2026-07-10, version 4.0.0*

Garbage.  Test robo call wasn’t blocked. It came through as a normal call.  Only Xfinity call guard blocked its call.  This is a waste of time you have to enter calls and had a technical error with the second options in settings don’t bother downloading

### 4/5 — Robocall blocker

*2026-07-04, version 4.0.0*

You always want more money for call filters and Scam shield.

### 4/5 — Could block more

*2026-07-04, version 4.0.0*

I get a lot of calls that are potential spam and ones that are definitely spam that sometimes don’t get blocked. Also, it would be helpful if I was able to paste phone numbers into the app to report and block them.

### 1/5 — Save your money

*2026-07-01, version 4.0.0*

It doesn’t stop robo calls. Save your money.

### 1/5 — kid porn

*2026-06-28, version 3.5.1*

kid porn

### 2/5 — Not working well anymore

*2026-06-23, version 3.5.1*

Used to work great and no longer blocks calls or texts effectively.

### 2/5 — Used to be great

*2026-06-20, version 3.5.1*

I originally found out about Nomorobo years ago because I still had a VOIP landline through Spectrum, which had Nomorobo as a free option to manage spam calls. I got it for my iPhone and liked it enough during the trial period that I ended up subscribing.

In the last year or so, I wonder if it's working at all. I am again getting multiple calls per day. When I report the number on Nomorobo, it invariably says it's a known Robocaller. 

I tried every online fix and even contacted their Zendesk support group. It still doesn't appear to be blocking anything -- except the test call from Nomorobo.

Nomorobo claims that their database updates constantly and that the number was added after I got the call. Seriously? Every time the call just happens to get reported in the 30 seconds it takes me to copy and paste the recent call into the Nomorobo reporting tool? 

Maybe it's just me, but I'm
about to ditch this formerly great app.

### 1/5 — Nomorobo robocaller

*2026-06-16, version 3.5.1*

Nomorobo listed numbers repeatedly still get through.  Why?

### 2/5 — It’s sucks

*2026-05-12, version 3.5.0*

I have to input numbers so many times a day. And the spam keeps coming.
