About this app

KnownCalls is the new ad-free and absolutely free call blocker app for Android that helps fight spam calls while respecting your privacy.

!This app only works with calls. For work with text messages, download the KnownCalls' version with SMS muting from its official website.!

With KnownCalls your phone will automatically reject calls from numbers not in your Phone book. It will save you time wasted on answering spam calls, and make you an uninteresting target for fraudsters.

This simple app works against telemarketers, anonymous or hidden numbers, robocalls, spam or other unknown calls, and various kinds of scammers.

! The app is for those who don't want to (or need to) answer calls from any unknown numbers.

!! This is a free app that DOESN'T provide tech support. Please use our online resources and community to get answers to your questions. However, you can mail us your ideas of improvement.


==NO INTERNET CONNECTION REQUIRED==
The app doesn’t use external resources. It works solely with your device’s Phone book so your privacy is safe!
Perfect for those who care about their digital imprint.


==WHY KNOWNCALLS IS BETTER==
1. Spammers usually call from different numbers each time, so adding each number to a block list might prove ineffective – next time they might just use another number. But KnownCalls blocks all unknown call numbers so it's not a problem any more.

2. Rejection of unknown callers is instantaneous because KnownCalls uses your device’s Phonebook only. Other call blocker apps usually work with a delay so you might be among earliest recipients that spam calls still get through to before being flagged as spammers.

3. 100% free. No hidden payments.

4. Absolutely no ads.

5. Extremely easy to use. 1 option to enable/disable blocking.

6. KnownCalls does not collect or send personal data or information on your phone calls anywhere - unlike other apps that use spam databases in the Internet and send your calls there too.

7. Installs well on almost any contemporary Android device.

8. Has additional internal pass and block lists (only for numbers that you interacted with after you had started to use KnownCalls).


STOP annoying robocalls or buzzing from call centers, telemarketers and fraudsters that always distract you when you're busy, wake you up in the middle of the night, or intend to scam you.
Finally you can enjoy the silence – and be sure that trusted callers still get through!

Recommend KnownCalls to your family and friends – let them feel the tranquility of life without spam too!

Ratings and reviews

Fantastic, incredible FREE app. No in-app purchases! (for real). Easy setup up and user friendly instructions. UPDATE: zero issues with this awesome app, I've been using it for a couple of months and I am still getting spam/scam calls. The same number calls me back at least 10 times in a row, but I don't hear my phone ringing anymore. SMS blocker is another of Known Calls perks. I am going to try it now. If only all my apps were this flawless. Virtual hug to Felenasoft.🫂

It actually works! Interface a bit awkward when it comes to settings, but it took me no more than 3 minutes to figure it all out. I've tested this app by calling from my backup phone (scam calls got scarce these days) - and yep, it works perfectly: number in the contacts = call comes through; number not in the contacts = no disturbance whatsoever. Happy, happy me! Thank you!

I live in Brazil and your application is an absolute joy, because of legal loopholes, telephone spammers make life miserable here and Samsung seem to ignore requests to be able to block unknown numbers, which your app does beautifully - thank you. What would be great to have, is the ability the export the list of blocked numbers in text format, with some basic filtering (numbers only, numbers with date and time) as the local regulatory body requires a list of numbers to take action.
