User Reviews

Overall, reviewers say NumberGuru used to be a strong reverse-lookup tool with detailed number intel, but it has deteriorated. The top issues are reliability (crashes, not launching, blank results), degraded data (few names; only city/state; sometimes no info at all), and a heavy subscription model with high fees and confusing charges. Privacy concerns surface in several reviews (data mining and potential data leakage). A few notes highlight that the app seems abandoned or not maintained. The sentiment is largely disappointment and a move to alternatives.

Pros

Super useful to find details on a number or look up address details.
Premier app back in the day to get good intel; could find out a lot of info with numbers.
Used to be quite useful.

Cons

Reliability and functionality have degraded: the app often won't launch or crashes and provides little to no information.
Subscription pricing: users report high monthly fees (e.g., $24.99/month) and paywalls; charges described as deceptive.
Privacy concerns: accusations of spyware/data mining and potential data leakage.
Data quality/availability has declined: few names; results are blank or limited to city/state, or inaccurate.
Maintenance and cancellation issues: app appears unmaintained and users report difficulty canceling subscriptions.

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.

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‼️
