The best app blockers for iPhone

Different app blockers solve different behaviors. A schedule helps when distraction has predictable hours. A delay helps when your thumb opens an app before you notice. A physical device makes changing your mind inconvenient. BookGate takes a narrower approach: it uses the blocked period to create a reading session.

That distinction matters more than declaring one app the winner for everyone.

How this comparison was prepared

This page was checked on 26 August 2026 against the companies’ own product pages and support documentation. It compares the main blocking mechanism and intended use; it does not reproduce every setting, price or platform-specific limitation.

Disclosure: This comparison is published by BookGate, which is included because it represents the reading-specific option. Its placement is not an independent review, and no paid placement or affiliate ranking is used.

Features can change. Follow the linked first-party sources before paying for any option.

Best free starting point: Apple Screen Time

Apple’s built-in Screen Time should be the first test for most iPhone users. Downtime can make most apps unavailable during chosen hours, and App Limits can cap daily use for an app or category. Apple also lets you turn on Block at Downtime so restricted apps cannot simply be opened during the scheduled period.

Choose it when you want to learn whether a schedule or daily allowance is enough before installing anything else. Move to another option when you need a different commitment mechanism, a cross-device block or a purpose for the reclaimed time.

Best for cross-device schedules: Freedom

Freedom combines blocklists, advance and recurring schedules, and a Locked Mode that prevents a session from ending early. Its clearest advantage is coverage across phones, tablets and computers, so the distraction cannot simply move from the iPhone to a laptop.

Choose Freedom when your problem follows you across devices and appears at predictable times, such as work hours or a nightly wind-down.

Best for detailed strict rules: AppBlock

AppBlock’s iOS product includes Quick Block, recurring schedules, usage limits and Strict Mode. That makes it suitable when you want several kinds of rule rather than one fixed focus timer.

Choose AppBlock when rule flexibility and resistance to changing those rules matter. The trade-off is complexity: the most useful setup is the one you can understand and maintain.

Best for interrupting reflex opening: one sec

one sec inserts an intervention before a selected app or website opens. Its current product also supports full blocks on a schedule, but the distinctive mechanism is the pause: it is designed to interrupt the automatic open before it turns into a session.

Choose it when you often arrive in a feed without consciously deciding to go there. If you deliberately choose to scroll, a pause may not be enough; use a stricter block.

Best for configurable friction: ScreenZen

ScreenZen combines pauses with app limits, blocks and schedules. It is donation-supported, which distinguishes it from the usual subscription model.

Choose it when you want to tune the amount of friction around different apps. Expect to spend some time deciding which controls are useful instead of enabling everything at once.

Best for reports alongside blocking: Opal

Opal combines app and website blocking with sessions, time limits, open limits, schedules and focus reports. Its own documentation says it uses Apple’s Screen Time API on iPhone and keeps device-activity data on the device.

Choose Opal when measurement helps you follow through and you want multiple kinds of focus rule in one place. If you only need one recurring block, a simpler tool may be enough.

Best for flexible iPhone rules: Jomo

Jomo organizes blocking around rules for apps and websites. Its documentation describes it as both a screen-time tracker and an app blocker, with several rule types managed from one place.

Choose Jomo when you want an iPhone-focused toolkit and prefer to construct the rule that matches the situation rather than adopt one fixed blocking philosophy.

Best physical commitment: Brick

Brick pairs an app with a physical device. You choose a mode and tap the phone against the Brick to activate it. The appeal is behavioral rather than technical: leave the device somewhere inconvenient and reversing the decision requires going back to it.

Choose Brick when settings on the same phone are too easy for you to change. It adds a purchase and a physical object to remember, which is either the point or unnecessary friction depending on your habits.

Best for replacing scrolling with reading: BookGate

BookGate is not a general productivity suite. At the reading time you selected, it rings like an alarm. You begin with a physical book, selected distracting apps are shielded for the reading session, and a short reflection closes the session.

Choose BookGate when the real sentence is, “I meant to read, but I scrolled instead.” Choose a broader scheduled blocker if you need protection throughout a working day or across several devices.

How to choose without overthinking it

Match the tool to the moment that fails:

1. You need a free daily limit: start with Apple Screen Time.
2. The distracting hours are predictable: choose Freedom or AppBlock.
3. You open apps automatically: choose one sec or ScreenZen.
4. You want blocking plus progress data: compare Opal and Jomo.
5. You override every software control: consider Brick.
6. Scrolling replaces the book you meant to read: consider BookGate.

Start with one rule for one week. If it fails, identify whether the problem was an easy override, the wrong schedule or an empty gap after the app disappeared. That tells you which mechanism to try next.
