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.

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.

Super handy, practical, and really useful app. No more calls from debt collectors or other shady types. Seeing the rating and skipping unwanted calls — that’s a win. Saves time and nerves. Everything’s great! Huge thanks to the devs!

One of the best apps of its kind. I love that you don’t have to set it as your default dialer — makes life easier. All I need is to know who called, not to make calls through the app. Five stars. Oh, and the interface is super clean and easy to use too!
