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.

Want free blocking that holds while you focus? Ice Block. Prefer a gentle free nudge? ScreenZen. Just want what's already on your phone? Apple Screen Time — though it's the easiest to ignore.
Frequently asked questions

What's the catch with free app blockers?
Some are trials or limit blocking to one app. Check whether free means real, ongoing blocking.
