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!

==HOW IT WORKS==
* Download KnownCalls call blocker app from Google Play or our website and install it on your device.
* Turn on filtering with 1 click.
* Done! All unknown calls from numbers that are not in your Contacts or Favorites will be automatically rejected without bothering you.

==SPAM PROTECTION FOR EVERYONE==

It's really helping a lot, but some spam/scam calls are able to leave me voicemails, and sending text messages about guaranteed loans. A lot of the voicemails left are nothing but complete static. The nerve-wrecking calls keeps my call log with at least 30 calls a day. It's ridiculous having to spent precious time deleting them all every day. This is extremely bothersome and entirely irritating. Fix this if you want or can. I'll find something else. Thanks.

This app is the best compared to Truecaller, Hiya, Call Control and Robokiller. This is the only app besides Truecaller that allows you to select only calls from my contacts. Truecaller is so annoying with the advertisement embedded in your contact list, asking for more control than it should and not as simple to use like this free app. I love it.

I normally don't write reviews I had to on this app. This app is fantastic. All the other call blockers can block but do you want to block 1000 numbers that these companies have to keep calling you back. The calls only in your address book can get through. You're doing a great service for all of us. THANKS.

known calls is a wonderful app. I was receiving all kinds of unwanted calls on my mobile and had to do something about it when my boyfriend showed me his phone and known calls app.It was a blessing!! Now that I have the app I can keep track of my calls and no more unwanted spam calls!! My phone is only letting in calls that I accept now and no more ringing off the hook!! It doesn't interfere with my phone or other apps either and installed perfectlh!! I recommend this appp!! Try it out!!

Great app for specifically blocking calls not in my contacts. Works perfectly. Love it. Would definitely pay money for this app that's how useful it is to me. Love the narrowly focused functionality. Especially love the minimal required permissions. The only thing that could make this app better is if it was open source.

Just to let you know this is the best free app out there. Sure it can't catch everyone of the scam calls but if you report those scammers they will take care of it. pdq. I highly recommend this app. And tell you this other apps make the claim. But only one as what it take. Get this app and get some of those paid app these people but out there. I guarantee it worth it.

My Do Not Call option on my Android doesn't work. I still get 6-8 calls a day from scumbags. Out of frustration, I decided to try this free app because it doesn’t have in-app purchases or ads. I just tested it twice by having a friend call me that isn't in my contacts. It works!!! My Z Fold phone didn't light up, ring, or show a missed call. I had to go into my phone app to see that I missed both calls. I'm telling all of my friends and family about this app!!!
