Scrolling does not stop because you decided it should. It stops when the reach costs something, when the trigger is gone, or when the same minute has a better job. This page covers why the usual advice fails, what holds up instead, and how to set it up on an iPhone in about ten minutes.
Almost every tip assumes a moment of choice. Be more mindful, set an intention, notice the urge. The problem is that the pickup happens before the noticing does: the hand moves in a gap, and awareness arrives two or three screens later. Advice aimed at a decision cannot work on a behaviour that contains no decision.
The second failure is free removal. Any limit you can dismiss in one tap costs nothing to dismiss, so it stops mattering within days. That is the whole reason iPhone Screen Time limits go decorative: the notification arrives, you press Ignore Limit, and the price of that press is zero.
| What people try | Why it appeals | Where it breaks |
|---|---|---|
| Willpower and resolutions | Free, immediate | Needs a decision point the behaviour does not have |
| Deleting the app | Feels decisive | The reflex moves to the nearest substitute, reinstalled within a week |
| Screen Time limits | Built in, no extra app | One tap to ignore, and the tap is free |
| Greyscale and notification purges | Genuinely reduce pull | Get reversed on the first inconvenient day |
| Total bans | Simple to state | Broken once, then abandoned entirely |

Any delay between the reach and the reward reduces the behaviour, and it does not need to be large. A few seconds of waiting, an extra step, a screen that will not open until something else happens. What friction cannot survive is being free to remove. The cost is the active ingredient, not the delay.
The minute you took back is still empty, and an empty minute is what the reach was answering. Something has to occupy it, ideally with your hands: a book in the same pocket, an instrument in the same room, food that needs cooking. A plan that only subtracts leaves a hole the phone will fill again by Thursday.
Rules attached to places and times hold better than rules attached to intentions. One room, one table, one hour. The charger in the hallway rather than beside the bed. These work because they need nothing from you at the moment of temptation, which is precisely the moment you have nothing to give.

Step one, find the hour. Open Settings, then Screen Time, and look at the daily graph rather than the total. You are looking for the hour with the most pickups, not the most minutes. For most people it is the hour before sleep or the first hour after waking.
Step two, name the two apps that own it. Not all of them. Two. Everything else stays untouched, which is what makes the change survivable.
Step three, put those two behind a real cost. Apple's own limits are worth trying first because they are free, and for some people the extra tap is enough. If Ignore Limit becomes automatic within a week, the limit is not working and no amount of resetting it will change that. That is the point at which a blocker with a price attached is the honest next step, whether that is Handover or anything else that cannot be waved away for free. The Opal Alternative page compares what the paid apps actually cost and where they differ.
Step four, decide what fills the hour. Write down the replacement before you arm anything. If you cannot name it, the rule will hold for three evenings and then be deleted on the fourth.
Step five, leave it alone for two weeks. Adding four rules on the first night is the commonest way to end up with none. One rule, one hour, two weeks, then add the next.

Move the charger out of the bedroom and put the two apps you reach for behind a rule that runs from an hour before bed. The charger move matters more than it sounds: it removes the phone from arm's reach at exactly the hour when your judgement is worst.
Because Ignore Limit is free. A limit only holds while dismissing it costs something you would rather keep.
Usually not for long. The reflex is not attached to one app, so the time moves to whatever is nearest, and the app tends to come back within a fortnight.
Give it two weeks. The first three evenings are the loudest, then the hour starts filling itself with whatever you put in its way.

Handover blocks the apps you choose and keeps a way back in that costs you something: a set of repetitions, a step goal, a barcode you left in another room, or days off the streak you have built. Five rules free, no card required.
