Scroll is not a traditional ad blocker, but we use a content blocker to help activate Scroll on iOS. This is because Safari's tracking protection currently does not provide a way for users to stay logged in to services they trust.
On desktop browsers and Android phones, Scroll will simply work automatically when you're logged in to Scroll.com.
To activate Scroll on iOS, download the Scroll app. The app will guide you through using the content blocker settings on your phone.
If you're still having issues with the content blocker in Safari on iOS, please check here for some additional troubleshooting instructions.
