Callblock

Callblock is an app that blocks phone calls from over 2 million telemarketers.

Callblock is something of a sequel to our ad blocker, Adblock Fast, which has 750,000 users and is rated 4.5 and 4 stars in the App Store and Google Play since launching alongside iOS 9 then the Samsung Galaxy S6. We’ve built on our experience filtering online advertisers to compile, classify, and apply what we think is the world’s biggest directory of telemarketers, with millions of entries from almost every country in the world.
