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 !!!

Phishing attempt using malware text message links

Have been a target by my X wives and associates for some time. Using malicious malware links via text message. Using this app to report them allows me to share these types of attacks with others. If you live in the Southern California area they are plentiful by this particular group to seize control of mobile phones. I only wished the technology was available to track these attacks to their true origin to create legally acceptable court evidence to prosecute these criminals utilizing the public cellular system for their gain.

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?
