Can you limit apps on an iPhone without paying for anything? Yes. Screen Time is already installed, it can cap any app or whole category by the day, and it takes about two minutes to set up. The steps are below. The more useful half of this page is the part after them, because the setup is not where limits fail.
The steps
- Open Settings, then Screen Time.
- Tap App Limits, then Add Limit.
- Pick a category, such as Social, or tap the arrow next to it to pick single apps. Picking one app is almost always better than picking a category, for reasons below.
- Set the time. Start higher than feels right.
- Tap Add.
- Open the limit again and turn on Block at End of Limit. Without this, the daily cap is a suggestion.
- Go back to Screen Time and set a Screen Time Passcode that is not your phone passcode.
Two related settings live in the same screen and do different jobs. Downtime turns the phone into a short list of allowed apps between two times, which is a schedule rather than a budget. Always Allowed is the exceptions list, and it should stay short. Messages and Phone are reasonable. A feed app on that list makes the rest of it pointless.
What each setting is really doing
An app limit is a daily budget with a reset at midnight. It counts foreground time only, so a video playing while the screen is off is free, and a feed you are reading is not.
Downtime is a schedule with no budget. Between the two times, everything not on Always Allowed is behind a screen. This is the better tool for the phone in bed, because the problem there is a time of day rather than a quantity.
The Screen Time passcode is the only part with real teeth. Without one, every limit on the phone can be turned off from the same Settings screen you just used, by you, in four seconds, at the exact moment you least want to be reasonable.
Where this breaks
Every limit on iOS ships with a door, and the door is called Ignore Limit. When the cap is reached you get a screen with the app name and a small option to ignore the limit for fifteen minutes, or for the rest of the day.
That option exists for good reasons. Apple cannot know whether the app you just hit a wall on is a time sink or the thing you need for work at that moment, and a phone that will not let you into an app during an emergency is a worse phone. So the door is correct, and the door is also the whole story.
What people describe is remarkably consistent. The limit holds for about four days. Then one evening the ignore tap happens with almost no thought behind it. The next evening it is faster. Within two weeks the limit screen is a thing you walk past rather than a thing that stops you. Nothing broke. It just stopped being a wall and became a doorknob. We took that pattern apart in full in what Ignore Limit really costs you.
The common response is to make the limit stricter, and that mostly makes it shorter lived. The stricter version produces a worse evening when you defeat it, and you will defeat it, so it gets uninstalled or switched off entirely. We wrote up what happens next in when strict mode made it worse.
Limits are one of six native and third party routes, and each breaks in a different place. The full comparison is in how to block apps on an iPhone.
Three ways to make a limit last longer
Set it higher than feels right. A limit you never hit is useless, but a limit you hit at 11am has taught you nothing except how to tap Ignore. Pick a number you would meet around the evening, then move it down once, later.
Limit one app, not a category. Social as a category includes the app you use to talk to your family. When the limit fires on that one, you will ignore it, and you have just practised ignoring it.
Give the passcode to someone else, carefully. This works and it has a cost, because the person holding it becomes the person you are negotiating with at midnight. Read what happens when a partner holds the passcode before you do it.
If the limit keeps getting ignored
At that point the tool is not matched to the failure. A limit answers the question "have I had too much of this today". It is a good question and it is not the one that produces most lost evenings.
Most lost evenings do not begin with a decision to spend time. They begin with a check. You picked the phone up to look at the time, your thumb went where it goes, and the deciding never happened. There was no moment to decide in, which is why a tool that arrives at minute thirty of a budget arrives late.
The other shape of tool puts something short in front of every open, including the first one, and then lets you in. No budget, no line to negotiate, nothing to defeat. That is described properly in what a scroll-breaker is and why it is not a blocker, and it is what reCalm does with a single breath.
Neither approach is a moral position. If the honest answer is that one specific app needs to be gone rather than slowed, use the limit with the passcode and mean it. If the honest answer is that you keep arriving somewhere you did not choose to go, a cap is the wrong instrument.
Frequently Asked Questions
How do I block an app on iPhone completely?
Screen Time cannot make an app permanently unreachable while it is installed, because Ignore Limit always exists. The closest you can get is a one minute limit with Block at End of Limit on, plus a Screen Time passcode you do not know. If it truly needs to be gone, deleting the app is faster, free, and does not require maintenance.
Why does my app limit not work?
Three usual causes. Block at End of Limit is off, so the cap only shows a notification. There is no Screen Time passcode, so the limit can be removed as easily as it was set. Or the app is on the Always Allowed list, which overrides limits entirely.
Do app limits work on the web version too?
Only if you also limit the browser or the site. Opening a site in Safari is usually the first workaround people find, and it takes about a day to find it. Screen Time can restrict specific websites under Content Restrictions, which closes that particular door.
Is a paid app blocker better than Screen Time?
For most people, no, at least not at first. Paid blockers mainly add friction to the exit, and the exit is not the real problem. Spend a week with Screen Time properly configured before paying for anything. If a limit you actually respected still did not change your evenings, the shape of the tool is what needs to change, not the price.
