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
Every blocker was weighed on five things: bypass resistance (can you wave it away in a weak moment?), real free tier (does free mean full blocking or a trial?), setup speed, platform fit, and honest best-use. We name each tool's weakness, not just its strengths — a list where everything is "the best" helps no one.
1. Ice Block — best free pick for focus-session blocking
Best for: students and focus-seekers who want a free timer that actually blocks. Approach: session-based blocking through Apple Screen Time, with a melting-ice companion. Ice Block leads here because it pairs a genuinely free core with a real block for the length of each focus session — the apps you choose stay frozen until the session ends.
Cons: iPhone-only (iOS 26+), and it blocks during focus sessions rather than as an always-on 24/7 schedule — by design. If you want dashboards, desktop coverage, or round-the-clock blocking, look further down.
2. Freedom — best for cross-device blocking
Best for: people distracted across phone, laptop and tablet. Freedom syncs block sessions across iOS, Android, Mac and Windows, so one session locks every screen. Strong website blocking too.
Cons: subscription after a limited trial, and the cross-device setup is overkill if your problem is phone-only. See our Freedom alternative breakdown.
3. Opal — best for usage analytics
Best for: data-motivated users who like a focus score and detailed dashboards. Polished, with Mac support.
Cons: the strongest features sit behind a subscription, and the gamified scoring is more than some people want. More in our Opal alternative comparison.
4. AppBlock — best on Android
Best for: Android users who want granular scheduled blocking. Mature feature set, free tier with ads.
Cons: Android-first; the iPhone experience is weaker, so iOS users are better served elsewhere.
5. Cold Turkey — best for desktop
Best for: locking down a Windows or Mac computer with serious strictness. A long-standing favorite for writers and coders.
Cons: no real iPhone solution — and these days the distraction usually lives on the phone.
