A better everyday experience
Your browser was only the beginning.
Take the next step from blocking website ads to protecting more of your device.
Take ad blocking into your apps
Browser extensions stop at browser tabs. Our Windows, Mac and Android apps filter traffic across your device, and the iOS app blocks in-app ads through DNS, so ads disappear from other apps too.
Get help from our team
A paid Ultimate license includes premium customer support. When you need help getting set up or adjusting protection, you have a team to turn to.
Compare what matters
More of your device. More protection.
Both offer free browser ad blocking without Acceptable Ads. Ultimate also offers paid apps for protection beyond your browser.
