Great app, and the support team is excellent. I reached out 2 or 3 times about negative comments — every time they replied and solved the issue. And I’m not even a paid user. Really impressed, thank you! They explain things clearly and take action. Felt genuinely appreciated.

Pretty good app. It identifies unknown callers better than others. The design is nice, clean, and easy on the eyes. It’s simple, practical, and does what it promises — solid five stars for quality!

Provides lots of info about the number — country, city, mobile carrier, and spam level.
