Worthless

Every number that comes up as spam on my phone has no information when I enter it into number guru. I think they have given my number to spammers, in fact. Deleting app.

FRUSTRATED

I have been using NG for the last 6 yrs. ; now, all I get is a red swirling icon whenever I try to use it! I haven’t been able to use it for a while now. I will have to try to find another source. NG was great when it was working; very disappointing‼️

Beenverified.com Spy app

Beenverfied.com runs this app. This is nothing more than spyware and data mining on your device.

Do not download or pay for it

It is not longer supported. I think the developers have forgotten about this and have moved on to other projects.

It no longer works

This app used to be useful a few years ago but in the last few months it’s doesn’t work and gives no real info when it does. Women if you’re looking to check guys for dating use the tea app or AWDTG app to run their numbers. It’s easy and actual works
