I first discovered and downloaded NumBuster a few years ago. And ever since, I’ve been impressed — and honestly happy I stumbled upon it. There’s nothing quite like it out there, nothing even close. Huge thanks to the creator — and please, don’t ever stop working on NumBuster. It just keeps getting better and better! Even though it already felt like everything was done, the developer keeps finding new ways to improve it!

I’ve been using NumBuster since day one. It’s honestly such a useful app! We work in the hotel business, and it’s always good to have a little more info about the client. That’s when NumBuster steps in — it helps protect you from “problematic” people. And lately, those aggressive types are showing up more and more. THANK YOU, NUMBUSTER!!!

Best app ever. You instantly see reviews if others have been called from the same number. Huge thanks for making this — everything is clear and easy to use. I’ve tried others, so I know the difference.

Solid number lookup. You can use it without paying, but the info is limited and some features are locked.
