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
iOS-specific criteria: native reliability (proper use of Family Controls / Screen Time), how well it holds in a weak moment, real free tier, and setup friction. Honest downside on every pick.
1. Ice Block — best free pick for focus sessions
Best for: students and anyone who wants to start a focus session and have distractions vanish. Ice Block freezes your chosen apps through Apple Screen Time for the length of each session, with a melting-ice companion making the commitment tangible. Free to download.
Cons: iPhone-only (iOS 26+), and it blocks during focus sessions rather than as an always-on 24/7 schedule — by design. Free tier caps sessions (Plus unlocks unlimited).
2. Opal — best for analytics
Best for: data-motivated users who want a focus score and dashboards, with Mac support.
Cons: strongest features are subscription-gated. See our Opal alternative.
3. Freedom — best for cross-device
Best for: people who also fight distraction on a computer; synced sessions and deep website blocking.
Cons: subscription after a trial; heavier than needed for phone-only use. See our Freedom alternative.
4. One Sec — best gentle option
Best for: mild habits that respond to an elegant pause before opening an app.
Cons: it's a pause, not a block, and the free tier covers only one app. See our One Sec alternative.
