This app is AMAZING!!

So I was skeptical at first because I’ve tried a million other apps that are supposed to work and provide all this information and they either don’t work or want you to pay a bunch of money…..NOT THIS APP!! This app really works!! Type in a phone number and you can literally use this app to find out ANYTHING on whoever’s number it is. Yes you have to pay for tokens which is like $3.99 but you get the name on the phone, their address, job, criminal history, if their married, who their related to, their email, and much more ! Totally worth it ! It really works! And if you think your spouse is cheating….well this app will tell you everything you need to know !! MUST HAVE APP!!!!! I’d give it 10 stars if I could !!!

I've been getting multiple spam calls a day lately so I've upgraded to premium. Premium must mean nothing because nothing changed. Searches still don't bring better results, spam calls are still not blocked, this app does nothing my phone's own blocker and a plain Google search can't do. What's the point of having it? I'm so frustrated I even paid that small amount just to have no adds maybe? Not worth it!

Developer Response ,

Hi Mamazsu, We're sorry to hear that CallerSmart Premium wasn't what you expected it to be. It's important to note that the Premium subscription comes with Premium Number Monitoring, which is different from our Premium Lookup Reports. Additionally, our automatic spam call blocker unfortunately can't block all spam calls, only those from numbers who have been reported to the FTC and in our phone book. You can reach us at if you'd like to let us know about any other issues you had. Thanks, Your CallerSmart Team

Not super helpful

I get at least 2 spam calls a day, sometimes more. The same scam (same recording) uses different phone numbers for every call. I got this app hoping it would help; I tried manually searching the numbers and marking them all as spam. 3rd number they called me with today came up as “this is not a phone number” in this app’s search function. Yes, it is a number, they were using it to bother me today. And so I gave up on marking the endless numbers as spam for other users.

Then today I got a wonderful 4th call for the day, and this app made no difference whatsoever. I activated the “filter out spam” feature of theirs through my settings, but spammers still called me just the same. What is even the point to this app, if it can’t find numbers being used to call you and doesn’t block phony calls?
