"How do I block this app on my kid's iPhone" sounds like it should have one answer. It has four, and they behave very differently. Choosing the wrong one is the reason so many parents block an app on Monday and find their child using it again on Wednesday.
Here is each method, what it actually stops, and how to pick.
Method 1: Block by Age Rating (Best for Blocking a Whole Tier at Once)
This stops any app above a rating you choose from being used or installed — including apps that do not exist yet.
- Go to Settings > Screen Time > Content & Privacy Restrictions and turn it on.
- Tap Content Restrictions > Apps.
- Choose an age ceiling: 4+, 9+, 12+, or 17+.
Use this when your concern is a category of content rather than one specific app. It is the only method that covers apps your child has not discovered yet, which makes it the strongest single setting for younger kids. Its weakness is that App Store age ratings are self-reported and frequently too generous — plenty of 12+ apps contain open chat with strangers.
Method 2: Block Installation Entirely (Best for Stopping the Reinstall Loop)
If you have ever deleted an app only to find it back the next day, this is the setting you were missing.
- In Content & Privacy Restrictions, tap iTunes & App Store Purchases.
- Set Installing Apps to Don't Allow.
- Set In-app Purchases to Don't Allow as well while you are here.
- Consider setting Deleting Apps to Don't Allow too — this stops the trick of deleting a monitored app to wipe its usage history.
Use this when the problem is not one app but a revolving door of them. Blocking individual apps is a treadmill you cannot win; blocking installation ends the race. Pair it with Family Sharing's Ask to Buy if you would rather approve downloads than forbid them.
Method 3: Hide a Built-In App (Best for Safari, Camera, and AirDrop)
You cannot delete Apple's built-in apps, but you can remove them from the device.
- Go to Content & Privacy Restrictions > Allowed Apps.
- Switch off anything you do not want available — Safari, AirDrop, Camera, Mail, and others.
Use this when the built-in app is the issue. Turning off Safari is particularly effective for younger children, since an unrestricted browser makes almost every other block irrelevant — anything you block as an app is usually reachable through the web.
Method 4: Block by Time Instead of Blocking Outright
Often what a parent wants is not "never" but "not now" — not during homework, not at 11pm, not for six hours straight.
- App Limits (Screen Time > App Limits) cap daily minutes per app or category.
- Downtime (Screen Time > Downtime) blocks everything outside your Always Allowed list during set hours.
Setting a category limit to one minute is the common workaround for an effectively permanent block that still lives under the same schedule as everything else.
Lock Everything Behind a Separate Passcode
Every method above is undone in seconds if your child knows the Screen Time passcode. Set one under Screen Time > Lock Screen Time Settings, and make sure it is not the same as the phone's unlock code. This is the single most common reason blocks fail, and it costs nothing to fix.

Where Apple's Blocking Runs Out
Apple's tools are genuinely capable at saying no. What they are not built for is the everyday middle ground most families actually live in.
Three specific gaps come up again and again:
- Changing a block means handling the phone. Without Family Sharing set up, most of these settings are adjusted on the child's device, not yours.
- Blocking is all stick, no carrot. Restrictions can stop a behavior. They cannot encourage a better one.
- Mixed households get two systems. If one child is on iPhone and another on Android, you are maintaining two unrelated sets of rules that work differently.
Blocking Less by Making Time Worth Earning
Tap Guardian approaches the same problem from the other direction. Rather than adding more things to forbid, it puts the day's screen time on a budget you set once and then lets your child extend it by doing things you have already approved — chores, homework, reading, or a quick Brain Boost quiz. Finish the task, the minutes are added.
In practice that changes what you are blocking for. Instead of playing whack-a-mole with individual apps, you set the overall envelope, and the apps compete for the time inside it. Your child starts making the trade-off themselves, which is the habit you actually wanted.
It also fixes the household split: iPhone and Android children are managed from the same dashboard, with the same rules and the same rewards. Tap Guardian is free for 14 days with no credit card, then $6.99/month or $49.99/year.
Tell Your Child What You Blocked and Why
A block your child discovers by hitting it is an ambush; a block they were told about is a rule. The second one generates far less effort spent trying to defeat it. Say what you restricted, say why, and say what would change your mind. Our guide on talking to kids about screen time covers how to have that conversation without it becoming a fight.
Final Thoughts
Match the method to the problem: age ratings for whole tiers of content, installation blocks for the reinstall loop, Allowed Apps for Safari and other built-ins, and time limits for "not now." Lock all of it behind a separate passcode, then shift as much of the work as you can from blocking toward earning. Blocks that exist alongside a clear way to earn time get tested far less often than blocks that are simply a wall.
