Turn on iPhone Screen Time

Do this, in order

1. 1

   Sit next to your child with their iPhone

   Unlock it. Tell them: "I'm making your phone safer." It's better if they know.
2. 2

   Find the grey app called Settings

   It has a picture of grey gears on it. It's usually on the first home screen. Tap it once.
3. 3

   Scroll down with your finger until you see "Screen Time"

   It has a purple square with a white hourglass. Tap it.
4. 4

   Tap the blue words "Turn On Screen Time"

   If you don't see those words, that's fine — Screen Time is already on. Skip to step 7.
5. 5

   Tap Continue, then tap "This is My Child's iPhone"

   A few screens will pop up asking about Downtime and App Limits. For each one, tap "Not Now" in the bottom corner. We'll come back to those another day.
6. 6

   Make up a 4-number secret code

   The phone will ask for a "Screen Time Passcode". Type 4 numbers your child does NOT know. Write them down on paper and hide it. Type the same 4 numbers again when it asks. If it asks for an Apple ID, tap "Skip" at the bottom.
7. 7

   Now you're back on the Screen Time page. Tap "Content & Privacy Restrictions"

   It's near the bottom of the list.
8. 8

   Tap the white switch at the very top

   It turns green. That means it's on.
9. 9

   Tap "Content Restrictions"

   A new page opens with lots of options.
10. 10

    Tap "Web Content"

    Then tap "Limit Adult Websites". A blue tick appears next to it. Done — most rude sites are now blocked.
11. 11

    Check the App Store age limits

    Tap the back arrow at the top-left twice. Then tap "App Store, Media, Web & Games". Set Movies, TV Shows and Apps to your child's age (for example "12+").
12. 12

    Stop them changing the safety settings

    Back on the "Content & Privacy Restrictions" page, scroll down to the list starting with "Account Changes". Tap each one and choose "Don't Allow".
13. 13

    Stop them deleting or installing apps

    Tap "iTunes & App Store Purchases". Set Installing Apps and Deleting Apps both to "Don't Allow".
14. 14

    Set a bedtime (Downtime)

    Back to Screen Time → tap Downtime → turn the switch on. Pick a Start time (e.g. 8:00 PM) and End time (e.g. 7:00 AM).
15. 15

    Set time limits on apps

    Tap App Limits → Add Limit. Tick Social and/or Games. Set 1 hour. Tap Add.
16. 16

    Lock who they can talk to

    Tap Communication Limits → During Screen Time → Contacts Only.
17. 17

    Test it together

    Open Safari and try a rude site — it should be blocked. Open Settings → Screen Time — it should ask for your code.
