I think they have given my number to spammers, in fact. Deleting app. ### 2/5 — FRUSTRATED *2026-01-21, version 4.2.82* 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‼️ ### 1/5 — Beenverified.com Spy app *2025-12-13, version 4.2.72* Beenverfied.com runs this app. This is nothing more than spyware and data mining on your device. ### 1/5 — Do not download or pay for it *2025-10-18, version 4.2.72* It is not longer supported. I think the developers have forgotten about this and have moved on to other projects. ### 1/5 — It no longer works *2025-08-20, version 4.2.72* 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 ### 5/5 — Great app! *2025-04-11, version 4.2.72* Super useful to find details on a number or look up address details as well. ### 1/5 — Useless APP *2025-02-17, version 4.2.72* Completely useless. Never pulls info on any number entered. Deleting now! ### 1/5 — Used to be better I SEE IM NOT THE ONLY ONE THAT THINKS IT USED TO BE GOOD BUT IS GARBAGE NOW *2024-12-02, version 4.2.70* Garbage, it used to give names & business names etc, the last 20 searches it doesn’t reveal anything tells the phone carrier, that’s it. Garbage app now. ### 1/5 — USED TO BE GOOD *2024-08-21, version 4.2.66* This was the premier app back in the day to get good intel. You could find out a lot of info with numbers. As of about two years ago, that all stopped. Now they don’t give you any information. Very wrong move by the developers as this used to stay on my phone. Now I download it in hopes it will give me info like it used to, but it never does. It’s trash now. ### 1/5 — Fraud - don’t pay a cent *2024-08-06, version 4.2.66* This app charges for services $24.99 but when you try use their services it keeps asking to parches again. Moreover, Apple bill department openly allowing this fraud on their Apple platform.. ## Frequently asked questions about NumberGuru ### What does NumberGuru do?
