How to block TikTok on iPhone

Semo is an iPhone app that blocks distracting apps by asking an AI question that quotes your own reason back to you. This page is only about TikTok.

How do you block TikTok on an iPhone?

It depends on what you mean by a block. Screen Time can limit TikTok, and you can ignore that limit if you know the passcode or never set one. Semo asks an AI question that quotes your own reason, and you can dismiss it. The steps on this page are Apple's. Semo is not on the App Store yet. Price shown in the app.

Block TikTok with iPhone Screen Time

TikTok sits with other social apps. On iOS 26, give it its own App Limit so the timer is not shared with every social app you still want. On iOS 27, TikTok falls under Social Media in Time Allowances, and that allowance is shared with the rest of the category until you adjust it. The For You page is the part that runs on; a limit on the TikTok icon does not by itself cover tiktok.com opened in Safari on iOS 26.

iOS 26

  1. Count TikTok before you limit it Open Settings, then Screen Time. If App and Website Activity is off, turn it on. Until it is on, a TikTok limit has nothing to count.
  2. Limit the TikTok icon, not all of Social Tap App Limits, then Add Limit. Open Social, and tick TikTok alone. A limit on the whole Social category also caps other social apps.
  3. Set the TikTok day, then check Always Allowed Tap Next, set the time, and use Customize Days if weekdays should differ. Then open Always Allowed and remove TikTok if it is listed, or the limit never starts.

iOS 27

  1. Put TikTok under a Social Media allowance Open Settings, then Screen Time, then Time Allowances. Turn on App and Website Activity if asked. Set the daily total, then set a shorter Social Media allowance if TikTok is the app you want to cut.
  2. Check whether TikTok's site is included On iOS 27, a website the app has linked can count toward the same allowance. Open Manage Categories and confirm TikTok is in the category you set. Safari can still open other sites.

Apple's steps: App Limits on iOS 26 and Time Allowances on iOS 27. A limit you set for yourself can be ignored if you know the Screen Time passcode, or if you never set one.

What TikTok's own limits do, and why they fail

TikTok's own Screen time control, under Settings and privacy, Digital Wellbeing, asks you to set a daily time and a passcode. The passcode is one you choose, so the prompt is something you can dismiss. The feed then continues from the same place. Sleep reminders and a restricted mode change what is shown or when a prompt appears. They do not close the app when the time is up. Notifications of new videos still ask you to open it, which is a separate switch under iPhone Settings, Notifications, TikTok.

An example reason

Written for this page. Not a quote from a user.

I open TikTok when I sit down to start homework, and the For You page takes the hour I meant to spend on it.

How Semo helps with TikTok

You can tell Semo that reason in your own words, and add a rule such as "a message from one friend is fine, the For You page is not". When TikTok is one of the apps you chose, Semo blocks it by asking an AI question that quotes that reason back to you. We have no published results for whether that question shortens TikTok sessions.

Questions

Does a Screen Time limit on TikTok also block tiktok.com?

On iOS 26, an App Limit on the TikTok app does not cover the website in Safari. On iOS 27, Time Allowances can include a website the developer has linked to the app. Check Manage Categories on your phone. Limiting Safari itself blocks every site, not only TikTok.

Why does TikTok's daily screen time let me keep watching?

The in-app daily time uses a passcode you set yourself, and the button to continue is part of that control. It is a prompt, not a limit held by someone else. A Screen Time passcode that another person knows is the stricter version of the system limit.

Can Semo limit only the For You page inside TikTok?

iOS cannot see which part of TikTok is on screen. Semo does not claim to block one tab inside the app. What you can do is write a rule in your own words, and the question Semo asks quotes that rule back when you open TikTok.
