The Best Free App Blockers for iPhone (2026)

"Free" hides a lot. Some apps are trials in disguise; others block only one app until you pay. Here are the genuinely free options that actually block — ranked, with the fine print spelled out.

What Ice Block actually is

Ice Block is a free iPhone focus timer (iOS 26+) built for students — and anyone who wants to actually start and finish a focus session. You choose the apps to freeze, and Ice Block enforces a real block through Apple Screen Time for the length of each session, while a melting-ice companion tracks your progress. Free to download; Ice Block Plus ($69.99/year or $14.99/month) adds unlimited sessions and weekly insights.

How we ranked these

Two rules: it must be genuinely free for real use (not a trial), and it must actually block rather than only report usage. We spell out exactly what each free tier includes.

1. Ice Block — best genuinely-free blocker

Free tier: download free and run focus sessions that freeze your chosen apps via Apple Screen Time, with a melting-ice timer. Plus ($69.99/yr or $14.99/mo) is optional for unlimited sessions and weekly insights.

Cons: iPhone-only (iOS 26+); the free tier caps how many sessions you can run, and it blocks per session rather than 24/7.

2. ScreenZen — best free friction tool

Free tier: fully free pause/intention screens before opening chosen apps.

Cons: it nudges rather than hard-blocks, so a determined moment beats it. See our ScreenZen alternative.

3. Apple Screen Time — best built-in (free)

Free tier: built into iOS — app limits, Downtime, and usage stats at no cost.

Cons: the one-tap "Ignore Limit" makes self-imposed limits easy to bypass. See our Screen Time alternative and why limits stop working.

Frequently asked questions

Is there a free app blocker for iPhone?

Yes — Ice Block (free to download), ScreenZen (free), and built-in Apple Screen Time.

Are free blockers any good?

The best ones genuinely block. Ice Block freezes apps during a session, more effective than stats-only tools.

Does Ice Block have a free version?

What's the catch with free app blockers?

Some are trials or limit blocking to one app. Check whether free means real, ongoing blocking.
