Great for discovering someone's identity

I got freaked out at work today (after walking a friend out to their car) when I received a text from an unknown number that they liked my shoes. They made comments about how they were watching me and how they know I'm a nice person. When they asked me how long I was going to be at work I was a little nervous to leave to my vehicle.

I remembered a friend recommending this app for me a couple days ago to help block pesky callers. I ended up using a different function to help me identify who this anonymous person may be. It didn't give me a direct name, but it listed the name of the company associated with the phone the person was using to text me from.

Only two people associated with that company knew my number so I realized immediately it was a harmless prank by one of my girlfriends whom I hadn't seen in a year. She had gotten a promotion and was surprising me at work.

This app truly calmed my nerves. I was two minutes away from calling the police because I was paranoid. Thank goodness I didn't do that 😅


Some how I keep getting strange messages or calls
And I love being able to look up these people .,
And mostly block them since I don't know them !!
And frankly I'm tired of paying a ton of money and getting no real info on the number .. This is the best !!!

Ok app

I have only used this app a couple of times so far but it has always been accurate with the info it has given. Does what it should
