KnownCalls - Whitelist calls

KnownCalls is a free app that helps protect your privacy and save you time by automatically rejecting calls from numbers not in your phone book. This includes telemarketers, anonymous or hidden numbers, robocalls, spam, and various types of scammers. It is perfect for anyone who wants to avoid answering calls from unknown numbers. The app does not require an internet connection, ensuring that your privacy is safe.

KnownCalls is better than other call blocker apps for several reasons. First, it blocks all unknown call numbers, rather than relying on a block list that may not be effective against modern spammers who use different numbers each time. Second, it works instantly because it only uses your device's phone book. Other apps may have a delay, allowing spam calls to still get through. Third, it is completely free with no hidden payments or ads. Fourth, it is extremely easy to use with just one option to enable or disable blocking. Fifth, it does not collect or send any personal information or information about your phone calls.

To use KnownCalls, simply download the app from Google Play or their website and install it on your device. Then, with one click, turn on filtering and all unknown calls from numbers not in your contacts or favorites will be automatically rejected. This app is perfect for anyone who wants to stop annoying robocalls, telemarketers, and fraudsters from distracting them or trying to scam them.

KnownCalls is also useful for different groups of people. Parents can use it to protect their children by creating a whitelist of trusted numbers and blocking all other calls. Public figures can use it to stop distracting phone calls while still allowing accessibility for known callers. Businessmen can use it to filter out spam call center calls while still receiving calls from their contacts. And seniors can use it to prevent scammers from taking advantage of them by blocking all unknown numbers.

In summary, KnownCalls is a unique and effective call blocker app that prioritizes privacy and ease of use. It is free and does not require an internet connection. It is perfect for anyone who wants to avoid answering calls from unknown numbers and can also be useful for parents, public figures, businessmen, and seniors. By using KnownCalls, you can become an uninteresting target for scammers over time. So why not recommend it to your family and friends and enjoy the peace and quiet of a life without spam calls?
