Direct answer: Open Settings, choose Screen Time, and turn on App and Website Activity. Use App Limits when you want a daily allowance for selected apps. Use Downtime when you want most apps unavailable during a schedule. Use a focused blocker when you need a clearer routine or stronger commitment. Always review essential access before making a block strict.

Apps that block apps on iPhone generally use one of these three approaches. Apple provides daily limits and blocking schedules. Dedicated tools can restrict access during a narrower routine and add more friction when you want to stay focused. Twilock blocks selected apps during Night and Morning windows, but it does not block websites.

Three useful ways to control app access

Make most apps unavailable at set timesDowntimeUses a recurring schedule with chosen apps always available
Protect a specific habit windowA focused blockerCreates a purpose built routine around the apps and times you choose

Method 1: block selected apps with App Limits

App Limits is the simplest Apple setting when you want to control a few apps without changing the rest of your iPhone.

  1. Open Settings and choose Screen Time.
  2. Choose App and Website Activity and turn it on if needed.
  3. Choose App Limits, then choose Add Limit.
  4. Open a category to select individual apps, or select a whole category.
  5. Choose Next and set the daily allowance.
  6. Use Customize Days if weekends need a different allowance.
  7. Save the limit and test what happens when the allowance ends.

If several apps share one combined allowance, remember that time used in any selected app can reduce the time remaining for the group. Separate limits are easier to understand when the apps serve different purposes.

Method 2: schedule a broader block with Downtime

Downtime is better when the issue happens during a predictable period such as bedtime, class, or a morning routine.

  1. Open Settings, choose Screen Time, then choose Downtime.
  2. Choose Scheduled.
  3. Select Every Day or customize each day.
  4. Set the start and end times.
  5. Turn on blocking during Downtime if you do not want the schedule to behave like an optional reminder.
  6. Open Always Allowed and confirm that calls, messages, maps, health tools, transportation, and authentication remain available when needed.

Test a new Downtime schedule while you are awake and calm. Open every app you may genuinely need before relying on the schedule overnight or away from home.

Method 3: use a focused app blocker

A dedicated blocker can make the boundary easier to understand. Different apps solve different problems, so choose the smallest system that matches yours.

Twilock is designed for unwanted scrolling near sleep. Its free Night window shields the apps or categories you choose for up to two hours. Twilock Pro adds a Morning window and Strict Mode. It is not an all day blocker, website blocker, parental control service, or emergency tool.

  1. Choose only the apps that begin the unwanted loop.
  2. Set a short window before the time you usually open them.
  3. Run the schedule normally for several days.
  4. Confirm that every essential app is outside the blocked selection.
  5. Add stronger commitment only if changing the rule is the loophole that remains.

If you need work sessions, website blocking, broad schedules, or several devices, read the screen time app comparison before choosing a tool.

Why an app may still open after you set a limit

The setting is acting as a reminder

Apple notes that Screen Time limits can be ignored by default. Review the blocking setting for Downtime and consider locking Screen Time settings if an easy override defeats the purpose.

The wrong app or category was selected

Categories can contain more or fewer apps than expected. Open the category and verify the individual apps instead of assuming the group matches your intention.

The schedule starts after the habit begins

A block that begins at midnight cannot interrupt a scroll that usually starts at ten thirty. Start the boundary before the first automatic check.

The rule is too broad to trust

If one necessary app is blocked, removing the entire rule becomes reasonable. Narrow the selection before increasing strictness.

If the limit still does not behave as expected, work through the App Limits troubleshooting checklist.

A safe first setup

  1. Select one or two distracting apps.
  2. Choose a thirty minute allowance or schedule.
  3. Keep essential communication and safety tools available.
  4. Test the rule before making it difficult to change.
  5. Review the result after three days and change only one weak point.

This smaller setup gives you useful evidence. You will learn whether the issue is total time, a specific part of the day, an easy override, or simply seeing the app icon.

Frequently asked questions

Can I completely block an app on iPhone?
Downtime can make apps unavailable during a schedule, while App Limits control daily use. The exact strength depends on your Screen Time settings and whether you can change them. Test the setup before relying on it.
Can I block only one app?
Yes. In App Limits, open the relevant category and select the individual app. Dedicated blockers can also let you choose individual apps through Apple Screen Time controls.
Can I block apps at certain times?
Yes. Downtime supports a recurring schedule. Dedicated blockers can also provide scheduled windows with different levels of commitment.
Can I keep Phone and Messages available?
Yes. Review Always Allowed in Screen Time, or leave essential apps outside the selection in a dedicated blocker. Always test urgent access before making a rule strict.
Does Twilock block apps all day?
No. Twilock focuses on Night and Morning windows, each capped at two hours. Choose a broader tool if you need workday or all day schedules.
