Most screen-time apps have the same theory of change: identify the app you shouldn't be using, block it, feel bad when you try. Cold Turkey locks you out. Opal takes over your Mac. Freedom kills your network. If you slip, you get an angry animation and a lecture. The premise is that willpower fails, so the tool should be the willpower.

The premise is half right. Willpower does fail. But there's a wide gap between "I need help noticing what I'm doing" and "I want to be punished for it," and the market has been building for the second when most people actually want the first. Hard-blocking works for a small number of users with genuine compulsions. For everyone else — the person who opens Twitter absent-mindedly ten times a day and would rather just not — it usually backfires. You uninstall the app, or you work around it, or you resent it enough to stop trusting it.

There's a smaller category of screen-time apps built around a different theory: you probably know what you're doing, you just don't notice how often. Give you gentle awareness — a colour that shifts, a soft chime, a peripheral counter — and you self-correct without ever hitting a wall. Here's the field.

Hard-block apps (worth knowing what they do)

Cold Turkey

Cold Turkey is the strictest tool in the category. Block apps, block websites, block your entire computer for a scheduled block of hours. There's a "frozen turkey" mode that removes your ability to disable the block until the timer runs out. If you have an active gambling or gaming compulsion and you've genuinely tried everything else, Cold Turkey is a serious option. It's also, by design, unpleasant to live with day-to-day.

Opal

Opal is mostly an iOS tool but its Mac companion applies the same model — blocked apps, scheduled sessions, streaks. Heavy gamification (streaks, "focus score," social features) makes it feel less like a utility and more like a habit tracker with punishment built in. Works for people who like gamified habits; friction for people who don't.

Freedom

Freedom blocks apps and websites at the network level across devices. Useful if you're context-switching between phone and Mac and want the same block on both. Less useful if the thing you need blocked is a Mac app rather than a website.

All three have their place. If you know the hard-block model works for you, one of these is what you want. If you've bounced off it, keep reading.

Soft-nudge apps

One Sec

One Sec is the most famous of the "friction not blocks" apps, though it started on iOS. When you open a target app, it makes you wait a second (or ten) while showing a breathing animation. That pause is enough that a real percentage of the time you close the app before it opens. It's a small idea that turns out to be surprisingly effective — you're not blocked, you're just briefly asked to notice what you're doing.

The Mac version exists but the experience is stronger on phones where the friction is more felt.

ScreenZen

ScreenZen also lives in the friction-not-blocks category. Configurable delay before opening target apps, plus session limits. Free, minimal, does one thing. The Mac support is more limited than iOS.

GentleLimit

GentleLimit is the app we built for the Mac specifically. It's built on three ideas:

  • Visual awareness in your peripheral vision. Calm progress bars for each app you're monitoring, colour-shifting gently as you approach your limit — green to amber to red. You can drag any row out into a floating widget and keep it visible without switching windows.
  • A soft cap, not a hard block. When you hit your daily limit, GentleLimit pauses the moment with a short optional overlay — step away, or extend by a few minutes. Never a lockout. The point is to make the moment noticeable, not punishable.
  • Cues you can turn down. An optional soft chime when an app reaches its limit; a subtle haptic feedback as you approach one. Both configurable. If cues aren't your thing, the visual progress is enough.

There's also an Insights view that shows patterns — immersion sessions, frequent context switches, high-usage days — so over a couple of weeks you get a real picture of how you're spending time, not just a nagging total.

GentleLimit is on the App Store and available direct. Menu-bar native, no dock icon, no tracking — screen time data never leaves your Mac. Small studio, one-time purchase.

The hidden option: macOS Screen Time itself

Apple's Screen Time is built into System Settings and it's underused. It shows per-app usage, has App Limits (which do enforce), and downtime scheduling. It's free, it's local, and it does the basics.

The reason people install third-party apps despite Screen Time existing: the enforcement model is either "on" (the app is fully blocked, you have to override) or "off" (informational only). There's no middle setting where the app tells you "you've hit your limit" without also making you fight the OS to keep using it. And the interface is Settings-based rather than a live indicator you glance at.

If you haven't tried Screen Time itself, do that first. If it doesn't fit — especially the on-or-off enforcement — the soft-nudge tools are where to look.

How to choose

If you have a compulsion you've genuinely tried to break and nothing has worked: Cold Turkey. It's the tool for that specific case.

If you're on both iOS and Mac and want a unified block across devices: Freedom.

If you like gamified habits and streaks: Opal.

If the moment of opening an app is where you want a small pause: One Sec (especially on iOS) or ScreenZen.

If you want ambient awareness — a colour shift in your peripheral vision, a soft cap that never locks you out, and a picture of how you're actually spending time over weeks: GentleLimit. It's the Mac-first tool for people who want the pattern to change without being punished into it.

Why the "gentle" side of this exists at all

The behaviour-change research on habits is mostly about awareness. When you can see a thing you're doing, you tend to do less of it — not because you've been ordered to, but because seeing it accurately changes what you want. Hard blocks skip that step. They enforce the outcome without teaching the pattern. That's fine if you've already decided; it's counterproductive if you're still figuring out what you actually want to change.

The gentle side of the category exists because for a lot of people the awareness itself is the intervention, and adding a block on top makes things worse, not better. Try the gentle tools first. If they don't work for you, escalate.
