Callfilter.app vs Getcontact

Callfilter.app is an Android app that blocks incoming calls according to rules set by the user. It can reject 8-digit numbers, numbers on a personal list, custom-pattern matches, or all incoming calls. Custom matching supports regular expressions, and users can choose to receive a notification when a call is rejected. CallFilter checks calls on the device through Android’s CallScreeningService API, using a local SQLite-based rule engine without remote database lookups. The maker describes it as offline, with no accounts or tracking. Its privacy policy says the app does not send personal data to external servers and does not use third-party SDKs, advertising networks, or tracking libraries. The app is free and open source, and the maker invites users to audit or contribute to the project on GitHub. It filters calls according to the user’s settings; it does not replace the phone app. The Play Store listing warns that some features may not work correctly on Samsung devices running Android 12 or later.

Getcontact is a caller ID and spam-blocking app that identifies calls from numbers outside a user's contacts and alerts them to unwanted calls. Spam Protection can automatically guard against robocalls, telemarketers, and scam calls. Users can also report unwanted calls, contributing to the community-powered number lookup that helps identify callers and flag spam. The free mobile app provides standard functionality. Premium adds ad-free use, information about who viewed tags or queried a number, private mode, a Premium badge, and three-month phone-number search statistics. Other monthly tariffs set allowances for searches and tag views: listed plans range from 100 to 1,500 searches and 10 to 150 tag views. Getcontact is available on Android, iOS, and web. To use Getcontact Web from a computer, users open the phone app and scan a code; minimum app versions are listed for Android and iOS. The Privacy Management Centre lets subscribers and non-subscribers adjust profile visibility, edit profile information, or deactivate a profile. Getcontact says it does not sell personal information and offers 24/7 customer support.
