How do I reduce my screen time?

Start with the two apps that eat the most hours instead of trying to fix everything at once. Put a real barrier in front of those two, and move the phone out of reach at the moments it gets picked up by default, like overnight. Two apps and one barrier, given two weeks, is enough to feel the hours come back.

Does Screen Time actually work?

As a report it is useful: it shows you which two apps are costing you the most. As a brake it is weaker, because app limits and screen-time reminders sit on the same phone as the apps, one tap from being dismissed in the exact moment you are least able to resist. A limit you can extend in two taps usually gets extended.

How much screen time is too much?

There is no single number that settles it, and picking one is not what makes the difference. What matters is what the hours are made of: for most people two apps take most of them, and those two are the ones worth cutting. If the easy path keeps leading back to the feed when you meant to stop, the default matters more than the total.

Why can't I stop using my phone even when I want to?

Most phone use is cued by proximity rather than desire: the phone is there, and the easy path stays one tap away. Advice built on willpower leaves that default intact, which is why it holds for about three days and then stops. Friction doesn't depend on your resolve, so it lasts longer.

How do I block apps so I can't just unblock them?

The block has to require an action your tired self won't take, which means the switch cannot live on the phone you are trying to escape. Anything you can undo in two taps will eventually be undone. Norma is one way to do it: you scan a steel disc with your iPhone, the apps you chose stay blocked until you scan again, and leaving the disc in another room keeps the block in place.

How to cut your screen time

To cut your screen time, start with the two apps that take most of your hours and put a barrier in front of them that you can't remove from the phone itself. Most screen-time advice asks for more discipline. The changes that last add friction in the right place instead.

The usual lists say: turn on grayscale, hide social apps in a folder, set an app limit. Most of these work for about three days and then stop, because each one leaves the easy path one tap away. Below is the principle behind the changes that last, and a method built on it.

The principle: make it harder to reach than to resist

A habit changes when the easy path stops being the default. The rest is detail.

The reason willpower-based advice fails is that it leaves the default intact. App limits and screen-time reminders sit one tap away, on the same phone, ready to be dismissed in the exact moment you're least able to resist: late, tired, bored. Friction that works sits off the screen, where a weak moment can't reach it. Researchers call the calm-moment version of this a commitment device: a decision you lock in now to protect you from the choices you'll be tempted to make later.

The University of California, Irvine's Gloria Mark has measured what each lapse costs: an average of 23 minutes and 15 seconds to refocus after a single interruption. The aim is to make those interruptions unavailable, rather than to sit through them on willpower.

Key takeaways

Remove the easy option instead of fighting the urge.
Friction works better than willpower because it doesn't depend on how you feel in the moment.
Put the barrier somewhere other than the phone you're trying to use less.
Decide once, while calm, and let the setup enforce it.

A method you can start today

1. Name the two apps that cost you most

Don't try to fix everything. Open your phone's screen-time report and find the two apps that eat the most hours; for most people it's a social feed and one more. Cutting those two is worth more than adjusting the other forty.

2. Move the trigger out of reach

Most phone use is cued by proximity, not desire: the phone is there, so you pick it up. Break the cue. Charge it in another room overnight instead of on the nightstand. The short walk is the friction, and it removes the two worst windows of the day: the last hour before sleep and the first after waking, when more than 80% of people reach for the phone within ten minutes of opening their eyes.

3. Block them with something you can't undo in two taps

This is the step the others depend on. Put a physical barrier between you and those two apps, one you set once and can't casually undo. A limit you can extend in two taps will get extended. The block has to require an action your tired self won't take.

Image to add: the steel disc resting on a desk beside a phone, the off switch, off the screen.

4. Protect the morning

Keep the feed off until you've started your own work for the day. The first hour sets the tone: if it begins inside an algorithm, the morning tends to go to reacting; if it begins with your own plans, the focus usually carries.

Where Norma fits

Norma is one way to do step 3. Scan a steel disc with your iPhone and the apps you chose are blocked until you scan again. The disc sits on your desk or by your bed, so unblocking means getting up and reaching for it, and leaving it in another room keeps the block in place without any willpower. With the free Mac app, the same scan also blocks the websites you choose. The mechanism is a passive NFC tag, the same kind of chip used for tap-to-pay.

Why this works when the tips don't

Each step above changes the default so the easy path no longer leads to the feed. Instead of relying on how you feel in the moment, you arrange your surroundings in advance, so the moment has nothing to decide. That's also why your screen time was never a discipline problem to begin with.

Start with two apps and one barrier, and give it two weeks. The hours tend to come back faster than you'd expect, and it takes no extra willpower.
