Best app I’ve ever seen. Huge database, and it keeps growing with new numbers all the time.

Awesome app! I ditched the default phone manager for this one and instantly realized I should’ve done it way earlier. If I could give more stars, I totally would!

It identifies unknown phone numbers when you type them into the search bar. Solid app — I recommend it!
