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!
