What AppBlock can and cannot block on iPhone

AppBlock uses Apple’s Screen Time framework to block apps and websites on iPhone. This means some things are possible, and some aren’t — not because of AppBlock, but because of how iOS works.

What AppBlock can block

  • Apps — any app installed on your device, including social media, games, and browsers.
  • Websites — domains and keywords in Safari and most major browsers.
  • App categories — block entire categories like Social or Games.
  • New app installationsAppBlock can hide the App Store via Strict Mode.
  • Settings and Screen Time — via Shortcuts (iOS 17 and earlier; limited on iOS 18+).

What AppBlock cannot block

  • Phone calls and SMSApple does not allow third-party apps to block the Phone or Messages app.
  • In-app content like Reels or ShortsAppBlock blocks the app entirely, not specific features inside it.
  • Browsing in apps with built-in browsers — these use in-app browsers that bypass website blocking.
  • Settings on iOS 26+Apple’s Shortcuts-based method no longer works reliably.
  • Screen Time settings directly — Apple restricts this for third-party apps.

A note on iOS limitations

AppBlock works within what Apple allows for third-party apps. When Apple changes their APIs or restrictions, some features may stop working or behave differently. We update AppBlock to match new possibilities as quickly as we can.
