Free app blockers for iPhone, and what free means here
We sell a subscription, so read this page with one eyebrow raised. snowscroll costs $49.99 a year and has no reduced edition, which means anyone searching for an iPhone blocker that costs nothing is, by definition, not our customer. The useful thing left for us to do is answer the question properly anyway, and then say plainly where we do not belong on the list.
Two things on this page cost nothing and keep costing nothing. Apple Screen Time is already on the phone, and ScreenZen states in one sentence that it will not charge you. Most of the rest of this category sets its price inside the App Store, where the word at the top of the listing refers to installing rather than to using.
Start with the controls already on the phone
Apple documents seven Screen Time controls: Downtime, App Limits, Communication Limits, Communication Safety, Content and Privacy Restrictions, Always Allowed and Screen Distance. Downtime is described as "Block apps and notifications for specific periods." App Limits is described as "Set a time limit for a category of apps (like games or social networking) and for individual apps." Checked against Apple's own Screen Time support page on 14 September 2026.
There is no price on that page because there is nothing to charge for. It arrives with the operating system, it covers every app on the device rather than a chosen handful, and it is the only thing on this page that a parent can enforce on somebody else's iPhone.
Adults drift away from it not because it breaks but because a limit is a quantity. It governs how many minutes an app stays open, and the smallest thing it can act on is an app or a category. Thirty minutes inside a recommendation engine is still thirty minutes inside a recommendation engine.
The outside option that is funded by donations
ScreenZen puts an intervention screen in front of an app you have flagged, with breathing and other activities to sit through while it unlocks, and it offers stricter blocking if the pause is not doing the work. Its site lists iOS, macOS, Windows and Android.
On money its site is unambiguous: "Do I have to pay to use ScreenZen? No. ScreenZen is completely free." It describes itself as "the only donation-supported screen time app that blocks distracting apps and websites." Checked on screenzen.co, 14 September 2026. Its App Store record the same day showed 4.9 stars from 49,509 ratings, last updated 6 September 2026.
That matters because it is not a sample of something larger. There is no level above it you are being walked towards, which in this category is rare enough to be worth saying twice.
The caveat nobody prints next to the word free
In August we counted every iOS app built to fight phone overuse that twelve frozen search terms returned, and read all 692 listings by hand. Three numbers from that pull, dated 30 August 2026, are the ones that should change how you read a store page.
- 681 of the 692 carried no upfront download price. Eleven were paid before install, at a median of $3.99 and a range of $0.99 to $4.99.
- Apple's search API has no in-app-purchase field at all. It reports the download price and nothing else, so free to download is not the same as free to use, and no amount of querying that API will tell you which apps charge later.
- 355 of the 692 descriptions, 51.3%, mentioned a subscription or a premium tier in their own words. Treat that as a text proxy and not as a measurement. It misses anything that charges without saying so in its listing, and it counts anything that still names a tier it has stopped selling.
So roughly half this category tells you it charges, in prose, somewhere below the fold. The other half we genuinely cannot classify from public data, and neither can anyone else quoting a number at you.
How to check any listing in about a minute
None of this needs a census. It needs three habits.
- Open the Information panel on the App Store product page. If an app sells anything inside itself, an In-App Purchases row sits there and expands into the named products and their prices.
- Read the bottom of the description. Auto-renewing products are named down there because Apple requires the terms, and that is usually where Premium or Plus first appears.
- Check Settings, your name, then Subscriptions. That list is what you are paying for now rather than what you think you are.
Cheap is not free, but it is not a renewal either
Three of the eleven apps that charged before install were Safari extensions from one developer: UnTrap for YouTube at $4.99, SocialFocus at $4.99 and Shorts Blocker at $1.99, from the same 30 August 2026 pull. They act on websites rather than installed apps, which SocialFocus says outright: "This extension does NOT work with the apps, it works only for websites while using the Safari browser." If your budget is close to zero rather than at it, $1.99 once is a different kind of decision from agreeing to a renewal.
Cost and reach, side by side
Every figure below is read from the source named in the note at the foot of this page, on the dates given there.
| What it costs | What it reaches | Where it runs | |
|---|---|---|---|
| Apple Screen Time | Nothing. It arrives with the operating system | Every app and category on the device, and it is the only entry here a parent can enforce on somebody else's iPhone | iPhone and iPad |
| ScreenZen | Nothing. Donation-supported, and its site says so in one sentence | Any app you flag, with an intervention screen in front of it | iOS, macOS, Windows, Android |
| UnTrap for YouTube, SocialFocus, Shorts Blocker | Paid once before install, never a renewal. The three amounts are in the section above | Websites, not installed apps | Safari |
| snowscroll | $49.99 a year, or $9.99 a month. No trial and no reduced edition | Six social services, and nothing else on the phone | iPhone |
Where we fit, and where we do not
snowscroll is the paid entry on this page and it is last on purpose. It is an iPhone browser. Sign in to Instagram, YouTube, TikTok, X, Facebook or LinkedIn through it and the surfaces built to run forever are not loaded at all, while messages, search, your profile and the accounts you follow carry on. It asks for Screen Time permission during setup, because that permission is what lets its shield catch a habitual tap on one of those six and land you inside snowscroll with the feed already gone. It reroutes you rather than refusing you.
What it costs, checked 14 September 2026: $49.99 a year, which works out at about $4.16 a month, or $9.99 charged monthly. There is no trial and no reduced edition. Referral codes grant days, and that is the only way in without paying.
Do not buy it if you arrived here because the budget is zero. That is not a modest disclaimer, it is the main finding of this page. Do not buy it either if the hours disappear into a game, a news app, a shopping app or a group chat, because we reach six social services and nothing else on the device. And do not buy it if you want something that refuses to let you in, since a redirect is not a wall and we would rather you heard that from us than found it out in week two.
If you want to narrow this down properly
There is a tool on this site that does the sorting: put your own constraints in and see what is left. It runs on the same 692-app dataset, costing nothing is a filter in it like any other, and it will happily return an answer that is not us.
Common questions
What is the best free app blocker for iPhone?
Two answers stand up. Apple Screen Time is already installed and reaches every app and category on the device. ScreenZen is the strongest outside option funded by donations rather than a subscription, and its own site says so in one sentence. Which suits you depends on whether a scheduled limit or a pause in front of the app is closer to your actual problem.
Is Apple Screen Time enough on its own?
For a lot of people it is, and trying it first costs an evening rather than a subscription. The reason people move on from it is rarely that it fails to run. It is that a limit governs how long an app stays open, and every one of its controls treats an app, or a category of apps, as the smallest unit it can act on.
Why do so many blockers say free and then ask for money?
Because the App Store lets an app carry no download price and still sell a subscription inside itself, and the listing you skim does not lead with that. In our census of 692 iOS attention apps, 681 carried no upfront price, yet 355 of the descriptions named a subscription or a premium tier. The word at the top of the page refers to installing, not to using.
Can I use snowscroll without paying for it?
Only with a referral code, which grants a number of days. There is no reduced edition and no trial, so if your budget for this is zero then the honest answer is that we are not the tool for you, and the two options at the top of this page are.
Keep going
For the full shelf there is a longer catalogue sorted by how each tool intervenes, and the counting behind these figures is published in the method, with the raw file attached. Apple's own controls get a longer treatment in the built-in timer, examined at length. If you are weighing the paid option anyway, there is the case for and against paying us, and the numbers themselves sit on a page with two figures and nothing behind them.
Prices, platform lists and feature descriptions on this page were checked on 14 September 2026 against Apple's Screen Time support page, screenzen.co and the Apple iTunes API records for each app named. Category figures come from our own census of 692 iOS apps, pulled on 30 August 2026. We have no affiliation with Apple, ScreenZen LLC or Yevhen Tretiakov, none of them were consulted, and every product name belongs to the company behind it.
