The 7 best free app blockers for iPhone
Almost every screen-time app has the same business model: block a bit for free, charge for the part that actually works. That's frustrating, and it's also why so many people conclude blockers don't work - they only ever tried the defanged free tier. These seven are genuinely usable without paying, ranked by the only metric that matters: whether they still hold at 11pm on a bad Tuesday.
Quick Answer
The best genuinely free iPhone app blockers are: FightMode (free, unlocks via a 60-second boxing round), iPhone's built-in Screen Time (free but easily bypassed), ScreenZen (free delays and intention prompts), one sec's free tier (breathing pause on limited apps), and Opal's free tier (basic sessions). Start with Screen Time to learn your failure mode, then add whichever free tool targets it - a pause for reflex opening, a physical toll if you keep disabling things.
What "free" means in this category
Three different things, and the distinction matters:
- Actually free. The core mechanism works forever without paying. Rare.
- Free tier. Works, but capped - three apps instead of unlimited, one schedule instead of many.
- Free trial. Not free. A countdown.
Everything below is in the first two categories.
1. Screen Time - free, built in, and the one you should try first
You already own it, and most people have never configured it properly. App Limits set a daily cap per app or category. Downtime blackouts a scheduled window. Combined, that's the core of what most paid apps sell.
The weakness: when the limit fires, iOS offers "Ignore Limit," and one tap later you're back in. Within two weeks that tap is muscle memory. Treat Screen Time as a measuring instrument first - two weeks of honest data telling you which apps and which hours are the problem. Setup walkthrough: how to block apps on iPhone.
2. FightMode - free, and the hardest to bypass
Free on the App Store with the core mechanism intact. Your chosen apps stay locked until you win a 60-second boxing round - a coach calls combos, an AI scorecard grades whether you actually threw them.
It solves the specific failure the other free tools share: they all end with a decision, and you make bad decisions when you're tired. There's no decision here, only a toll. And unlike a countdown timer, the minute produces something - a month of unlocks is a month of conditioning you didn't plan for. See why boxing works as friction.
3. ScreenZen - the best free delay tool
Free, no subscription, and more configurable than Apple's built-in options. Set a delay before an app opens, require a stated intention, cap the number of opens per day. If your problem is unconscious reaching rather than deliberate bingeing, this may be all you need.
4. one sec (free tier) - a pause on your worst app
The free tier limits how many apps you can guard, which is fine - guard the worst one. The breathing pause interrupts autopilot better than a warning dialog does. See where the pause approach runs out.
5. Opal (free tier) - basic sessions
The free tier gives you limited focus sessions. Enough to find out whether scheduled blocking suits how you actually work before committing to a subscription. Opal alternatives, compared.
6. Focus modes - free, and nobody uses them properly
iOS Focus modes aren't a blocker, but they're a free and badly underrated layer. A Focus can hide entire Home Screen pages, silence app notifications, and switch automatically by time, location, or when you open a specific app. Hiding the icon removes the visual trigger, and a huge share of opens are triggered by seeing the icon rather than wanting the app.
7. The free things that aren't apps
Zero-cost changes that beat most paid blockers
Charge the phone outside the bedroom. The highest-leverage single change available to most people.
Delete the app, keep the account. Reinstalling takes a minute and a conscious decision - that's the friction.
Log out and forget the password. A real toll, applied every time.
Turn on grayscale. Accessibility, Display & Text Size, Color Filters. Strips a surprising amount of the pull.
Move the app off page one. Into a folder, on the last page, unsorted. Removes the visual cue.

The free stack that actually works
- Week 1-2: Screen Time on, no limits, just data. Find your two worst apps and your two worst hours.
- Week 3: Downtime over your worst window. Move the two worst apps off page one. Charger out of the bedroom.
- Week 4: Add a real toll on those two apps - a pause if you're an autopilot opener, an exercise unlock if you're a bypasser.
- Ongoing: Review the weekly report. If a number stops moving, change the mechanism, not the app.
Total cost: nothing. See also how to stop doomscrolling.
Frequently Asked Questions
What is the best free app blocker for iPhone?
For pure blocking power at no cost, FightMode is the strongest free option because the core mechanism isn't paywalled and there's no dismiss button - you unlock by winning a 60-second boxing round. iPhone's built-in Screen Time is the best free starting point for understanding your habits, and ScreenZen is the best free delay-based tool. Which one is right depends on whether your problem is reflex opening or deliberate bingeing.
Is Screen Time good enough on its own?
It's good enough to measure your habits and to enforce a schedule you already want to keep. It's not good enough to stop a determined bypass, because the Ignore Limit button is one tap away at exactly the moment your resolve is lowest. Use it as your data source and your first layer, then add something with a real cost on the two or three apps where the hours actually go.
Are free app blockers worse than paid ones?
Not inherently. What separates a working blocker from a decorative one is the mechanism, not the price. A free app that makes you do something physical will outperform a subscription that shows you a dismissible dialog. Paid tiers mostly buy breadth - more apps, more schedules, cross-device sync - rather than a fundamentally stronger block.
Can I block apps on iPhone without downloading anything?
Yes. Screen Time's App Limits and Downtime, Focus modes that hide whole Home Screen pages, grayscale via Color Filters, moving icons off the first page, and simply deleting an app while keeping the account are all free and built in. Stack three or four of them and you have a real system before you install a single thing.
