How to set app limits on iPhone (and actually stick to them)

First, check which iOS version you have

iOS 27, released on September 14, 2026 for iPhone 11 and later, redesigned Screen Time. App Limits became Time Allowances and Downtime became Screen Time Schedules. As Apple puts it, allowances set how long and schedules set when.

Check in Settings › General › About. On iOS 26 or earlier, follow the first set of steps; on iOS 27, the second. Most guides online still describe App Limits, which is why the menus you see may not match them.

Set App Limits on iOS 26 or earlier

1. Open Settings › Screen Time. If it’s off, turn it on so your iPhone starts recording how long you use each app.
2. Tap App Limits, then Add Limit.
3. Choose a whole category (Social, Games, Entertainment…) or expand it and tick only the apps you want, like Instagram or TikTok. Tap Next.
4. Set the daily time. Customize Days lets you allow a bit more on weekends.
5. Turn on Block at End of Limit and tap Add.

One detail that matters: apps in the same limit share it. Thirty minutes for “Instagram + TikTok” means thirty minutes between them, not thirty each. That usually works better than one limit per app, because scrolling hops from one to the other.

Time Allowances in iOS 27: where app limits went

1. Open Settings › Screen Time › Time Allowances. If prompted, turn on App & Website Activity.
2. At the top, set a total daily time for the whole device with the + and − buttons.
3. To limit just one category, tap Manage Categories, then the + button. Pick, for example, Social Media, or create a custom category with the apps you choose.
4. Adjust the allowance with the slider or + and −, then tap Done.

Two changes worth knowing. First, an app stops being available when either its category allowance or the device total runs out, whichever comes first: if raising the category allowance does nothing, check the total. Second, if you use schedules, Match Screen Time Schedule gives each time window its own allowances (for example, no social apps from 9 to 2).

For your evenings, go to Settings › Screen Time › Screen Time Schedule, turn on Schedule, tap Add Schedule and add a night window that only allows the apps you really need. There’s a full walkthrough in how to stop using your phone before bed.

Why your app limits aren’t working (and how to fix it)

The usual problem isn’t setting the limit up. It’s that it dissolves. When you hit it, your iPhone covers the app with a screen, but without a passcode you just tap Ignore Limit and choose 15 more minutes or the rest of the day. Two taps, and at 11:40 p.m. two taps stop nobody. These are the levers that do help:

• Set a Screen Time passcode. In Settings › Screen Time, tap Lock Screen Time Settings and create a passcode that’s different from your unlock code. If you make it up yourself you’ll know it, so ask someone else to type it in for you. Then extending your time means asking them.
• Always turn on Block at End of Limit. Without it, the limit is just a reminder. It’s set per limit, so check each one.
• Start with a limit you can keep. Look at your daily average in Settings › Screen Time and start a little below it. A limit you break every day ends up being ignored out of habit.
• Leave out what you need. Add Phone, Messages or Maps to Always Allowed so you never have to bypass the limit for something important.
• Check your time zone and clock. Limits reset every day at midnight; if the time is wrong, so is the counter.

There’s a simple idea behind this: what helps most isn’t a taller wall but a moment to think before going in. A study published in PNAS in 2023 looked at an app that adds a short pause before opening social media and found that, over the weeks, people tried to open those apps less. Small, consistent friction works better than a punishment you learn to skip.
