How to block apps on your iPhone while you study

Your iPhone can already block apps. It's all in Screen Time, it's free, and nothing needs installing. The catch is that Apple built it for daily habits, not for the two hours you need to get a paper done. Here's how to set it up for studying, and where it falls short.

Menu names below are from recent versions of iOS. If yours look a little different, search Settings for “Screen Time.”

Option 1: Downtime, for set study hours

Downtime blocks everything except the apps you allow, on a schedule. It's the closest built-in thing to “lock my phone from 7 to 9.”

1. Open Settings, then Screen Time, then Downtime.
2. Turn on Scheduled and set the hours, or set different hours for each day.
3. Turn on Block at Downtime if you see it. Without it, Downtime is more of a suggestion.
4. Back in Screen Time, open Always Allowed and add only what you need for school: maybe Canvas, a calculator, your notes app.

Good for: a regular study block every weeknight. Not good for: “I'm starting now,” since it runs on a fixed schedule, and it blocks nearly everything rather than just your problem apps.

Option 2: App Limits, for the apps that eat your time

App Limits block chosen apps after you've used them for a set time each day.

1. Open Settings, then Screen Time, then App Limits, then Add Limit.
2. Pick a category like Social, or open it and pick single apps.
3. Set the time. The smallest limit is one minute, which works as a near-total block.
4. Turn on Block at End of Limit.

Good for: cutting down overall. Not good for: studying. The limit counts across the whole day, so it can run out at lunch or not at all, and it doesn't care when your homework is.

Option 3: a Study Focus, for notifications

Focus modes silence notifications from everything except the people and apps you choose. In Settings, open Focus, tap +, and make one called Study. You can also have it hide distracting home screen pages while it's on.

A Focus doesn't stop you from opening an app. It stops the app from calling you. Pair it with one of the options above.

The part that decides whether any of this works

Every Screen Time block has an escape: a button to ignore the limit for a minute, fifteen minutes, or the rest of the day. If you know the Screen Time passcode, that button is one tap away, and in the middle of a hard assignment you will tap it.

So the passcode is the lock. Under Screen Time, choose Lock Screen Time Settings (called Use Screen Time Passcode on some versions) and have someone else type it, a roommate or a friend you trust, so you don't know it. Make sure your Apple Account details are right first, since that's how you reset it if you're ever truly stuck.

Where Screen Time falls short for studying

• It runs on clocks, not assignments. It knows it's 7 PM. It doesn't know your essay is due at midnight or that you already turned it in.
• Starting a session takes digging. There's no one tap for “block my apps for the next 45 minutes.”
• The escape is all or nothing. Either you know the passcode and the block is weak, or someone else does and you have to ask them for every exception.

That gap is why app blockers exist. Some put a deliberate pause before an app opens, some make you scan a physical object to unlock, and some tie the lock to something you're supposed to be doing.

The low-tech option still wins

Put the phone in another room. When we asked eight students where their phone is while they study, most said right next to them, on the desk or in a pocket. A couple of them had tried moving it to another room or into a bag, and one said studying somewhere public helps. Distance is the one block with no ignore button.
