The Best Screen Time Apps, Tested for a Month
Five popular screen-time apps, tested for a month against normal day-to-day phone use rather than compared on paper. ScreenZen is the one to start with for most people; the other four earn their place for a specific failure mode.

The short answer
Start with ScreenZen. It's free, works on both platforms, and targets the most common failure mode: dozens of short, reflexive checks rather than a few long sessions. Add Freedom if your scrolling also happens on a laptop. Add One Sec specifically if your problem is opening apps without deciding to, not staying in them once open. Move to Cold Turkey only once you've tried the others and need something that genuinely cannot be undone mid-session. Forest is worth adding on top of any of these if you want structured, scheduled focus sessions rather than all-day control. The split is deliberate rather than a ranking: ScreenZen, One Sec and Forest are soft (they delay you, they never stop you) Freedom is firm across phone, tablet and computer at once, and Cold Turkey is the only one here built so that restarting, reinstalling or deleting will not lift a block. Match the tool to your failure mode rather than to its price.
This list comes from a month-long trial run on this site, one app at a time, roughly a week each, against ordinary phone use rather than a lab setting. That means it's one person's experience over one month, not a controlled study, and it covers five apps rather than the entire category. Pricing and platform details below are checked against each vendor's own page; where a profile doesn't show an exact figure, the vendor doesn't publish one to check.
How they differ
| Feature | ScreenZen | Freedom | One Sec | Cold Turkey | Forest |
|---|---|---|---|---|---|
| Best for | The most common failure mode: dozens of short, reflexive checks | Blocking that has to hold across phone, tablet and computer at once | Compulsive opening, the reach before the decision | Serious procrastination once gentler tools have already failed | Scheduled, timeboxed focus sessions rather than all-day control |
| How hard to undo | Soft. It delays you, it never blocks you outright | Firm. A locked session is difficult to end early, but it is a single app you control. | Soft by design. It only delays you, never prevents you. | Very hard. Its stricter modes are designed so that restarting, reinstalling or deleting will not lift a block. | Soft: nothing stops you leaving the app, the tree just dies |
| Platforms | iOS, Android | iOS, Android, Mac, Windows, Chrome | iOS, Android | Mac, Windows | iOS, Android |
| What it costs | Free, donation-supported | $8.99/month, $3.33/month billed annually, or $99.50 once | Free essentials, with a one-off purchase covering all your devices | Free tier, with a one-time purchase for Pro, no subscription | Free tier, with a Plus upgrade priced per region and platform |

Common questions
Which one should I actually start with?
ScreenZen, unless you already know your problem is specifically cross-device scrolling (Freedom) or a locked-in commitment device (Cold Turkey). It's free, so trying it costs nothing but a week.
Do I need more than one of these?
Possibly, but not to start. They solve different failure modes: reflexive short checks, cross-device leakage, compulsive opening, absolute enforcement, and scheduled sessions, so pick the one that matches your actual pattern rather than installing all five at once.
Is this list exhaustive?
No. It's five apps the site tested first-hand over one month, not a survey of the whole category. For a platform-specific shortlist, see the best blockers for iPhone or the best free website blockers.
