Screen Time on iPhone is enabled through Settings, tracking app and website usage while allowing you to set Downtime, App Limits, and content controls for yourself or your child.
One tap in the wrong menu and the feature stays dark. The actual switch is three screens deep, buried under a name that sounds like a report card rather than a parental control system. Enable it once and the iPhone logs every minute you spend scrolling, plus gives you the tools to cap it. Here is the exact path to turn it on, whether you are locking down your own phone or managing a child’s device.
Where The Screen Time Switch Lives
Apple does not put the toggle on the Home Screen or inside a quick-settings panel. It sits inside the main Settings app, inside a submenu that itself has a submenu. The current path on iOS 17 and 18 is the same:
- Open Settings.
- Tap Screen Time.
- Tap App & Website Activity.
- Tap Turn On App & Website Activity.
The screen will flash for a moment, then show a daily usage graph that starts counting from zero. That is the if you see the graph, Screen Time is live and tracking everything you open.
Setting It Up For A Child’s iPhone
Managing a child’s Screen Time from your own phone adds two prerequisites Apple does not always make obvious. You must first have Family Sharing configured, and you must have added the child’s Apple Account to your family group. Without those two steps the child’s name will not appear under Family inside Screen Time.
Once Family Sharing is ready, the path is:
- Open Settings.
- Tap Screen Time.
- Under the Family section, tap the child’s name.
- Follow the onscreen prompts to choose Downtime, App Limits, and content restrictions.
- When prompted, tap Lock Screen Time Settings and enter a 4-digit passcode twice to confirm. This passcode keeps the child from changing the limits later.
Apple specifies that if you do not own an iPhone or iPad but your child does, and the child is between 13 and 17 years old, you can still set up and manage Screen Time directly on the child’s device using the same sequence above.
How To Share Limits Across iPhone, iPad, And Mac
A limit set only on the iPhone means the child can pick up the iPad and keep watching. Apple’s Share Across Devices toggle fixes that single-device gap. After Screen Time is on, go back to Settings → Screen Time and turn on Share Across Devices. Every device signed into the same Apple Account will then enforce the same Downtime schedule and App Limits.
The common failure point is mismatched software. If one device is running an older iOS version, the settings will not sync correctly. Apple recommends updating all devices to the latest OS before turning on or changing any Screen Time setting across a Family Sharing group.
What You Can Control Once Screen Time Is On
Three toggles make up most of what parents and power users actually need. Each one lives inside Screen Time after you have enabled App & Website Activity.
| Control | What It Does | Where To Find It |
|---|---|---|
| Downtime | Blocks all apps except those on Always Allowed during a set schedule | Settings → Screen Time → Downtime |
| App Limits | Sets a daily time cap per category or individual app | Settings → Screen Time → App Limits → Add Limit |
| Always Allowed | Chooses contacts and apps that stay available even during Downtime or after a limit is hit | Settings → Screen Time → Always Allowed |
Each control requires App & Website Activity to be on. If you turn off App & Website Activity, all three of these lose their power — Downtime, App Limits, and Always Allowed all stop working because the underlying tracking engine is disabled. Turning off only Downtime or deleting a single App Limit does not disable the whole system; the full shutdown happens only when you toggle off App & Website Activity.
How To Fully Disable Screen Time
The quickest way to stop all Screen Time reporting and restrictions is to go back to Settings → Screen Time → App & Website Activity and turn that toggle off. A confirmation prompt will appear because turning it off wipes the current usage history and disables every limit and schedule you set. If you want to keep the history but pause restrictions temporarily, just turn off Downtime or remove individual App Limits instead.
Common Setup Mistakes And How To Avoid Them
- Forgetting the passcode. When setting up a child’s device, skip the Lock Screen Time Settings step and the child can turn off all restrictions in seconds. Enter the 4-digit passcode during setup and do not share it.
- Share Across Devices is off. By default each iPhone, iPad, and Mac maintains its own Screen Time settings. One device with Share Across Devices turned on and another without creates a gap.
- Family Sharing not fully configured. The child’s name will not appear under Family in Screen Time until the child’s Apple Account is added to the family group. Set that up first or the management screen stays empty.
- Devices on different software versions. A parent’s iPhone on iOS 18 and a child’s iPad on iOS 16 may not sync limits reliably. Update everything to the current version before setting up Screen Time controls.
Screen Time Passcode Checklist
One passcode controls all the protection. Here is the sequence that locks it down correctly:
- Enable Screen Time on the child’s device or via Family settings on your own phone.
- Tap Lock Screen Time Settings when the option appears during setup.
- Enter a 4-digit passcode the child does not know.
- Confirm the passcode by entering it again.
- Store the passcode in a password manager or a note the child cannot reach.
If you lose that passcode, Apple cannot recover it — the only workaround is erasing the device and restoring from a backup made before Screen Time was locked. Keep the code somewhere safe.
