Comments on KnownCalls - Whitelist calls for Android

★★★★★ Don Tobias · Jun 6, 2026

I really like the way this app works!!! I subscribed because of a scam call that keeps bothering me DAILY. And they have a large list of telephone numbers! I think "Known Calls" may have removed 4 of their numbers, but I have to verify this. If true, I will write back. The name they use is "Potential Spam", and I don't know what their game is, but it can't be good!! Thank you, Don

★★★★★ Sean Masters · Dec 16, 2025

This app works great for blocking any calls not in your contacts.

★★★★★ Robin Searcy · Apr 2, 2026

This app is awesome. Perfect way to handle unwanted calls, and it does it perfectly

★★☆☆☆ rancid crawfish · May 22, 2026

Looks like it could work. But there's ZERO information on this app. It doesn't show any options to create a white list OR a black list. But there are options to block people on the black list and only allow calls from the white list. It even lets you know your white list is empty. But there's no way to make the god-damn list. And if there is, it isn't obvious or easy.

Not working. I just received a call from Indiana not in my contacts, and it didn't block it

★☆☆☆☆ Mama M · Jul 13, 2026

This app may have worked in the past but not working in today's world. I gave this app about a week since it's not blocking any of my unknown calls. I even emailed them. I received no response. This app is still not working. The unknown calls are still coming through. I'm not sure what its purpose is except for occupying space on my phone.
