Shieldio
Blocks ads, trackers, cookie notices and other annoyances in Safari on iPhone and iPad. Pay once, no subscription, and no data collected.
What it blocks
Five simple switches. Turn on what you want gone.
Ads
Banners, sponsored boxes and requests to ad networks.
Trackers
Analytics scripts, tracking pixels and other data collectors that follow you from site to site.
Cookie notices
Cookie and consent banners are hidden.
Annoyances
Newsletter and notification pop-ups, app banners and other page clutter.
Social widgets
Like and share buttons and embedded posts. Off unless you turn it on, because some pages need them.
Turn it on once
Shieldio uses Safari's built-in content blocking, so Safari needs your permission once. Shieldio walks you through it on first launch and checks each step.
- Open the Settings app and go to Apps > Safari > Extensions.
- Open Shieldio — Ads, Shieldio — Trackers and Shieldio — Annoyances in turn, and turn on Allow Extension for each.
- That's it. Shieldio's status changes to Protected.
On iOS 26.2 and later, a button in Shieldio opens the right screen in Settings for you.
Private by design
- Shieldio can't see what you browse. Safari applies Shieldio's rules itself. Content blockers have no access to the pages you visit or anything you type.
- Nothing collected. No account, no analytics, no ads, no tracking, and no server of our own.
- Fresh lists, straight from the source. Shieldio downloads updated filter lists from the people who maintain them, over HTTPS, with no identifiers and none of your settings. You can turn automatic updates off. See the privacy policy for exactly what is sent.
- Works offline from the start. A recent copy of every list comes with the app.
Good to know before you buy
- Safari only. Shieldio works in Safari and in web pages that other apps open with Safari's built-in viewer. It can't block ads in other browsers, in apps' own built-in browsers, or inside apps.
- No YouTube video ads. Content blockers can't block ads that play inside videos on YouTube.
- One site acting up? Turn blocking off for just that site with Safari's own controls. Here's how.
- Requirements: iPhone or iPad with iOS 18 or later.
Price
- $2.99 once
