Most schools now allow phones in bags but not in hands, and enforcement varies enormously between classrooms. Plenty of parents decide to handle it at the device level instead — the phone stays available for contact, but the distracting apps simply do not open between 8:30 and 3:15.
Here is how to set that up on an iPhone, and the one Apple limitation that trips almost everyone up.
Option 1: Downtime on a Custom Schedule
Downtime blocks everything except your Always Allowed list during hours you choose.
- Open Settings > Screen Time > Downtime on your child's iPhone.
- Switch it on and choose Customize Days.
- Set your school hours on Monday through Friday, and leave Saturday and Sunday off.
- Open Always Allowed and trim it hard — Phone and Messages usually stay, most else does not.
Because the schedule is per-weekday, you can also handle early finishes and a different Wednesday without touching anything else.
Option 2: One-Minute Category Limits
If you only want a handful of apps gone during the day rather than everything, App Limits are the lighter tool. Set a category like Social or Games to a very small daily allowance and it is effectively unavailable — though note this caps the whole day, not just school hours, so it is a blunter instrument than it first appears.
The Limitation Nobody Mentions: One Downtime Window
Here is where the straightforward plan runs into a wall. Apple gives you a single Downtime window per day. You can customize it per weekday, but you cannot have two separate blocks on the same day.
That is a real problem, because most families want exactly two: school hours during the day, and a curfew at night. With one window you have to choose. Some parents stretch a single window across both and accidentally block the afternoon; others cover bedtime and give up on school hours entirely.
The common workaround is to use Downtime for the night curfew and lean on tight App Limits for the school day. It works, but the school-day portion is now a daily total rather than a genuine time window — a child who does not touch their phone in the morning still has the full allowance available in class.
Getting Both Windows Properly
This is a case where a dedicated app solves something Apple's tools structurally cannot. Tap Guardian has separate school and bedtime schedules rather than one shared window, so both run on the same day without competing. School hours can end at 3:15 and the evening curfew can start at 9, with the afternoon left alone in between.
Because it is set per weekday, a Wednesday half-day or an exam week does not require dismantling anything. And you set it from your own phone rather than borrowing theirs — including without Family Sharing or a child Apple Account, which is often the blocker for families whose devices were not all bought and configured together.
The other half is what happens outside those windows: your child extends their remaining time by completing tasks you approve — homework, chores, reading, or a Brain Boost quiz. During term that points the incentive at exactly the things school already demands. It runs on iPhone and Android from one dashboard, free for 14 days with no credit card, then $6.99/month or $49.99/year.
Lock It Behind a Separate Passcode
Whatever you configure, set a Screen Time passcode under Lock Screen Time Settings that is different from the phone's unlock code. A school-hours block that a child can switch off in the corridor before first period is not a block. This is the most common reason these setups quietly fail — for the rest of them, see how kids get around iPhone Screen Time.
Check Your School's Policy First
Worth five minutes before you configure anything. Some schools run their own device rules, some require certain apps to stay reachable for timetables or announcements, and some expect students to be contactable during specific windows. Building your block around the school's actual policy avoids a conflict on day three.
Tell Your Child What You Set
A block discovered mid-lesson is embarrassing and generates immediate effort to defeat it. A block explained beforehand is just a rule. Say which apps are unavailable, during what hours, and what stays reachable so they can still contact you. That last part matters most to them — the fear is being cut off, not being limited.
Final Thoughts
Downtime on custom days handles school hours well, right up until you also need a night curfew and discover Apple only offers one window. Decide which one matters more, or use a tool with genuinely separate schedules. Either way, lock it behind its own passcode and tell your child what you did — the technical setup is the easy half.
