Ratings and reviews

I have tried many tracing methods and paid for apps. But this app gives accurate information. I tested it on my number. In fact, it is a little scary how accurate the information is. The app reveals information about myself that does not appear on Google, Microsoft, and many other platforms. past

Unable to report or block a number from a lying scammer

After your free trial, this app is utterly useless, unless you want to subscribe for $13/month. And the trial is over & gone in 3 days (!) ... that's so quick I never even got the chance to try it, not that I really care all that much. If I needed this service that badly I would've already had one for the same price or way less from one of the many companies with good reps that are all over the place online.
