Set Time Limit App iPhone iOS 12

To set a time limit on an app in iOS 12, go to Settings > Screen Time > App Limits, tap Add Limit, choose the app category, set the amount of time, and tap Add. This feature, introduced in iOS 12, lets you cap daily usage for specific apps or entire categories, after which the app is blocked until the next day or until you approve more time.

What Is Screen Time in iOS 12?

Screen Time is a built-in feature that tracks how you use your iPhone and iPad. It shows a weekly report of your activity, including time spent in each app, how many times you picked up your device, and which apps send you the most notifications. More importantly, it gives you tools to manage that usage: App Limits (which we’re focusing on), Downtime (a schedule when only allowed apps work), and Always Allowed (apps that bypass limits).

Screen Time works across all your devices signed into the same Apple ID, so limits you set on your iPhone also apply to your iPad (if you enable “Share Across Devices�). It’s designed to help you reduce mindless scrolling, curb social media overuse, and create healthier digital habits.

How to Set an App Time Limit (Step by Step)

1. Open Settings on your iPhone.
2. Tap Screen Time.
3. If you haven’t set it up yet, tap Turn On Screen Time and then Continue. You’ll be asked if this is your device or your child’s. Choose accordingly.
4. Tap App Limits.
5. Tap Add Limit.
6. Select the app category (e.g., Social Networking, Games, Entertainment). You can also select multiple categories by tapping each one. If you want to limit a single app, you can’t pick it individually – you must choose its category. (In later iOS versions you can pick specific apps, but iOS 12 only allows categories.)
7. Set the time limit using the hours and minutes wheels. You can set different limits for different days by tapping Customize Days.
8. Tap Add in the top right.

Once the limit is reached, the app’s icon will gray out and a timer appears. You can tap Ask for More Time and either enter your Screen Time passcode or approve it if you’re a parent. If you don’t want to allow extra time, just ignore the prompt.

What Happens When the Limit Is Reached?

When you hit the daily limit, the app is blocked. You’ll see a message that says “You’ve reached your limit� and a countdown of how long until the limit resets (which is at midnight by default, but you can change it in Screen Time settings). You have two options:

• Ask for More Time – This requires your Screen Time passcode (if you set one) or, if you’re a child, a parent’s approval.
• Ignore – You can’t open the app until the next day (or until the limit resets).

Note that if you set a limit for a category, all apps in that category share the limit. For example, if you set a 1-hour limit on “Social Networking,� then using Instagram for 30 minutes and Twitter for 30 minutes uses up the full hour combined.

How to Set a Passcode to Prevent Changes

If you’re setting limits for yourself and want to prevent yourself from bypassing them, you can set a Screen Time passcode. This is also essential for parental controls. Here’s how:

1. In Settings > Screen Time, tap Use Screen Time Passcode.
2. Enter a 4-digit passcode (or a longer one if you prefer).
3. Enter it again to confirm.

Now, to change limits or approve more time, you’ll need this passcode. If you forget it, you can reset it using your Apple ID password (if you enabled that option). Note that on iOS 12, you can’t recover a forgotten passcode without resetting the device, so write it down somewhere safe.

Common Problems and How to Fix Them

Many users run into a few issues when using App Limits in iOS 12:

• Limits not applying to a specific app – Because iOS 12 only allows category limits, you can’t limit a single app. If you want to limit only one app, you’ll need to block the entire category, which affects other apps too. A workaround is to delete the other apps in that category or use a third-party parental control app.
• Limits resetting at the wrong time – By default, limits reset at midnight. To change this, go to Settings > Screen Time > Downtime > Start & End (or in App Limits, tap Customize Days and look for the “Limit Resetâ€� option). In iOS 12, you can set a custom reset time under Screen Time > App Limits > Customize Days.
• App still accessible after limit – Sometimes the limit doesn’t block the app if the app is in the “Always Allowedâ€� list. Check Settings > Screen Time > Always Allowed and remove any apps you don’t want to be exempt.
• Screen Time not showing data – If the tracker isn’t recording usage, make sure Screen Time is turned on and that you haven’t disabled it in Settings > Screen Time. Also, restart your iPhone.

Alternatives to Screen Time App Limits

If Screen Time doesn’t meet your needs, there are other ways to limit app usage on iOS 12:

• Downtime – Instead of per-app limits, Downtime lets you schedule a block of time (e.g., 10 PM to 7 AM) when only apps you choose are available. This is useful for bedtime or work hours.
• Third-party apps – Apps like Freedom, Offtime, or Moment can block apps or websites, but they often require a subscription and may not work as seamlessly with iOS 12 as they do with later versions.
• Manual self-control – Turn off notifications for distracting apps, move them to a folder on the last page, or delete them temporarily. This isn’t a technical limit, but it can help.

For parents, Screen Time in iOS 12 offers a “Family Sharing� setup that lets you manage your child’s devices remotely. You can set limits, approve purchases, and see activity reports from your own iPhone.

Frequently Asked Questions

Can I set a time limit for a single app in iOS 12?

No, iOS 12 only allows you to set limits for entire categories (e.g., Social Networking, Games). You cannot pick a single app. If you need to limit just one app, you’ll have to either block the whole category or use a third-party app.

How do I change the time limit after setting it?

Go to Settings > Screen Time > App Limits, tap on the limit you want to change, then tap Edit (or just tap the time value) to adjust the hours and minutes. You can also delete the limit entirely by swiping left on it and tapping Delete.

What happens if I ignore the “Ask for More Time� prompt?

If you don’t tap “Ask for More Time,� the app remains blocked until the limit resets (usually at midnight). You can’t open it, but you can still receive notifications from it (unless you also disable those).

Does Screen Time work on older iPhones?

Screen Time is available on any iPhone that can run iOS 12 or later. That includes iPhone 5s and newer models. However, some features like “Share Across Devices� require you to be signed into iCloud.

Can I set different limits for weekdays and weekends?

Yes. When adding or editing a limit, tap Customize Days and you can set different time limits for each day of the week. For example, you might allow 2 hours on weekends but only 30 minutes on weekdays.

Will Screen Time limit my usage of built-in apps like Safari or Mail?

You can set limits for system apps as well. In the App Limits list, you’ll see categories like “Productivity� which includes Mail, Calendar, and Safari. You can select those categories and set a limit, but note that some core functions (like making phone calls) are not affected.
