About this app

The Call Filter is a simple and effective app to block unwanted calls. The app is free, does not contain ads, and does not collect or transfer personal data and contacts.

The Call Filter automatically blocks the following types of incoming calls:

- Advertising and intrusive services over the phone;
- Calls from scammers;
- Calls from debt collectors;
- Intrusive offers from banks;
- Surveys;
- "Silent calls", instantly dropped calls;
- Calls from the numbers in your personal blacklist. Wildcards are supported (optional);
- All incoming calls from the numbers that are not in your contacts (optional);
- Any other unwanted calls.

The Call Filter does not require access to your contacts!

Unlike other blocker apps, Call Filter does not require access to your contacts. It is easy to use and stable in operation.

The blocked numbers database is updated several times a day. Your phone chooses the refresh rate automatically based on the state of your battery, Internet connection speed, and connection type (Wi-Fi, LTE, H+, 3G, or EDGE). The Call Filter is designed to update the blocked numbers database as often as possible, without draining your battery, wasting extra traffic or slowing down your Internet access when you use it.

Ratings and reviews

For months now I have received spam calls three times or more per week from a specific area code and prefix with the last 4 digits changing. I installed this, used the wildcard option to block the above mentioned problem and haven't received one in over three weeks. It doesn't show any blocked calls from that series of numbers or any notifications though and I'm wondering why not. I do believe this is the best call filter app anywhere. Tried others but this one is a true masterpiece. Thanks!

Finally, a call blocker that really does block calls. Occasionally, something makes it through to voice mail, and that is not often. When I block a number, it is blocked. I don't get any notifications on my phone, my watch, or my car, which, for me, is a relief. Other call blockers would have a notification of a block call and put them to voice mail. The calls would always ring through my car and watch, regardless of whether they were blocked or not. Call Filter stops the call.

FINALLY!! Call filter really does filter any incoming calls that are not in my contact list!! I was previously using Verizon's call filter which was nearly useless It lets so many unsolicited phone calls through. I've deleted it since this Call Filter works so well. It's important to remember to add doctor's phone numbers, etc. to your contacts

What's new

1. Added additional notification when the app doesn't see some incoming calls.
2. Significant optimization of the phone number verification module. Now the app works more stable on older and/or slower phones.
