What Instagram actually offers
Three settings get repeated in every guide to this question. Turn off "Reels made for you" notifications, under Notifications → Live and Reels. Switch your main feed to Following, which drops recommended content including reels. Mark reels Not Interested one at a time to retrain what gets suggested.
All three do something. None of them touch the part most people mean when they say they want Reels off: the tab itself, sitting in the bottom navigation bar, and the reel player that opens the moment someone sends you a link.
Why there's no real off switch
Reels is Instagram's answer to TikTok, the same way YouTube Shorts is. It's the format Meta is currently optimizing engagement around, which makes an off switch a direct hit to the thing the feature exists to grow. The settings that do exist are aimed at relevance, not removal, tuning which reels you see rather than whether you see any.
What's left: the web version
Instagram's web version runs the same core app: feed, Following, DMs, Stories, all functional. And because it's a web page, a Safari extension can act on it before anything renders, which the native app's sandboxing doesn't allow.
On the web version, that means:
- The Reels tab disappears from navigation, not just the notifications about it.
- Reel links resolve differently, so a link someone sends still opens instead of erroring, but without dropping you into the vertical Reels player.
- The main feed goes chronological, following-only, with the algorithmic Home mixed feed hidden underneath it.
- Explore's reel-heavy grid hides too, while search inside Explore keeps working.
None of that requires retraining an algorithm one dismissal at a time. It's just gone.
Making the web version the one you land on
Same problem as any of these fixes: you have to actually open the web version instead of tapping the app icon out of habit. A personal iOS Shortcut, run automatically when the Instagram icon is tapped, can hand you off to the fixed web version instead.
That's the whole mechanism behind DoomOff: a Safari extension that removes Reels, Explore's grid, and Stories where you choose to, paired with a guided Shortcut that makes the cleaned-up version the default. Every toggle has a live preview before you turn it on, so you can see exactly what changes.
