How to Block X (Twitter) on iPhone: App, Site & Doomscroll

X — still "Twitter" to most people — is the app of just checking. Checking the news, checking the replies, checking whether the thing everyone's angry about is still happening. Each check is short. Together they fill the day, and the late-night ones are the worst.

Here's how to block X on iPhone — the app and the website, under both its old and new names.

Quick answer: on iPhone, the most reliable built-in way to block X is Settings → Screen Time → App Limits, with Block at End of Limit on and a Screen Time passcode someone else holds. Add x.com and twitter.com to the blocked websites so the browser isn't a back door. If you want a block that holds even when you're mid-scroll, use a dedicated blocker (more below).

Why is X so hard to put down?

X is built on novelty and conflict. The For You timeline is algorithmic and endless, and outrage travels fastest, so the content that keeps you scrolling is often the content that makes you feel worst. Pull-to-refresh turns checking into a slot machine: sometimes something new, usually nothing, always worth one more pull.

How do I block X with Screen Time App Limits?

These steps work on iOS 16 through iOS 26.

1. Open Settings → Screen Time. If it's off, turn it on.
2. Tap App Limits → Add Limit.
3. Find X — open the categories or use the search bar — and select it.
4. Set a time. To block it almost completely, choose 1 minute; to cap it, choose something like 20 minutes.
5. Turn on Block at End of Limit. (You need a Screen Time passcode for this — Settings → Screen Time → Lock Screen Time Settings, or Use Screen Time Passcode on iOS 16.)

When the limit hits, X greys out on your Home Screen. Without a passcode, though, the limit screen just offers Ignore Limit — which is why the passcode matters. See how to remove "Ignore Limit".

How do I block X at certain times?

For a time window — nights, work hours, dinner — use Downtime:

1. Settings → Screen Time → Downtime.
2. Turn on Scheduled and pick your hours (e.g. 9:00pm → 7:00am).
3. Under Always Allowed, make sure X is not on the list.

News-driven doomscrolling peaks at night. A Downtime window that starts a couple of hours before bed protects your sleep from breaking-news spirals.

How do I block X in Safari and other browsers?

An App Limit only covers the app. X works perfectly well in a browser, so close that door too:

1. Settings → Screen Time → Content & Privacy Restrictions (turn it on).
2. App Store, Media, Web & Games → Web Content → Limit Adult Websites (on iOS 16 to 18.0, the first menu is called Content Restrictions or Store, Web, Siri & Game Center Content).
3. Under Never Allow, add x.com and twitter.com.

This blocks the site completely in Safari and in apps that use Apple's web view. It's all-or-nothing — there's no time limit option for websites here.

Does X have a time limit?

No. X has no built-in daily limit or break reminder. What helps inside the app:

• Switch to the Following tab instead of For You — a chronological feed of accounts you chose has an end.
• Mute words and topics: Settings and privacy → Privacy and safety → Mute and block → Muted words.
• Cut notifications: Settings and privacy → Notifications — turn off recommendations and "trending" alerts.

These make X calmer. They don't limit it.

Can I lock X behind Face ID?

Yes. On iOS 18 and later, long-press the X icon, tap Require Face ID, and confirm. You can also choose Hide and Require Face ID to move it into a hidden folder in the App Library.

It adds a second of friction and stops other people opening the app — but your own face unlocks it instantly, so it won't stop you.

Why don't these blocks hold?

X blocks leak through the browser (x.com and twitter.com both work), through links shared into group chats, and through the feeling that you'll miss something important. Blocking it completely can feel like cutting yourself off from the news, so the block tends to come off during any big event.

More broadly, every built-in method has the same weakness: you set it, so you can undo it. The App Limit has an "Ignore Limit" button or a passcode you know; Downtime has "Ignore Limit" too; the website block can be switched off in Settings; Face ID is your own face. We cover every gap in Screen Time loopholes.

And a daily limit is the wrong shape for X. Most X checks are under a minute. The damage is the evening scroll where you refresh for an hour. A daily total gets used up by the quick checks and then gets ignored.

What's a way to block X that actually holds?

Detox is an iPhone and iPad app built for the moment the built-in tools fail: mid-scroll, low willpower.

• Consecutive-usage limit: open X to look something up or read a thread someone sent — that's fine. Once you've been scrolling X continuously past your limit (say 20 minutes), Detox hard-blocks the X app for a cooldown. Step away for about a minute and the counter resets, so quick checks never add up to a lockout.
• Schedules: block X completely at set times — e.g. every night from 9pm.
• Focus sessions: a countdown block for deep work or study.
• Websites too: add x.com and twitter.com so the browser isn't a way round.
• Strict mode: while a block is active you can't edit or delete it, and Detox can stop you deleting the Detox app itself during a strict block. The emergency unblock is capped at one per 24 hours.

Detox blocks the whole X app, not individual parts of it. It's iOS only, paid, with a free trial.

Which method should you use?

The bottom line

To block X on iPhone, set a Screen Time App Limit with Block at End of Limit, and add both x.com and twitter.com to Never Allow so the browser isn't a way round. Switching to the Following tab and cutting notifications takes away a lot of the pull. If you want to stay informed without the late-night refresh loop, limit continuous sessions rather than the day.
