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!

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!

Good app. The community updates it, which is great. Really helpful when there’s too much spam — you can filter and only take the calls that matter. Highly recommend!

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.
