Block Reels on iPhone
You don't want Instagram blocked. You want Reels blocked. Screen Time can't do that — it's all-or-nothing. Dull can. It's an iOS app that loads Instagram in a browser and strips Reels, Explore, and suggested posts before the page draws. Feed, Stories, and DMs still work. 7-day free trial, then $3.99/mo.
Most 'block Reels' advice online comes down to: use Screen Time, delete the Instagram app, or try a Shortcut automation that breaks on the next update. None of them actually block just Reels — they either block all of Instagram or pretend the content isn't on the page. Dull removes Reels at the DOM level inside its own browser, which is the only way iOS allows a third-party app to touch Instagram's UI.
