TL;DR — Most "focus apps" do roughly the same thing — block websites and apps for a while. The differences that matter are how hard they are to bypass, whether they target the Mac or your phone (the actual problem), and what they cost. Quick picks: Cold Turkey for serious blocking, One Sec for a softer nudge, Apple Focus if you want free, PhoneDown if your problem is the phone next to your laptop. Yes, I make PhoneDown — full disclosure below, the comparison is honest.
I've spent years cycling through every focus / blocker / phone-shame app on macOS, mostly because I needed one to work and none did. Here's an opinionated breakdown of what's actually out there in 2026, what each one is good for, and where each one breaks down.
Disclosure: I make PhoneDown, the last app on this list. I've kept the writeup blunt about what it doesn't do. If a different app on this list is right for your situation, pick that one — I'd rather you stay focused than buy mine.

Freedom
What it is: The original cross-platform blocker. You set a session, pick a list of websites/apps to block, and Freedom enforces it across your Mac, iPhone, iPad, and Windows machines simultaneously.
Pros: The cross-device thing is genuinely useful — blocking Twitter on your laptop is pointless if you can just unlock the phone and open it there. Polished, reliable, has a recurring-schedule feature that's good for routine.
Cons: Subscription pricing for what is essentially a list of domains plus a system extension feels rough. The app blocks the websites, not the urge — when a session ends, you'll often immediately go check the thing you were blocked from.
Pick this if: you want polished cross-device blocking and don't mind paying yearly.
Cold Turkey Blocker
What it is: The most unforgiving blocker on the Mac. Pro version supports "Frozen Turkey" (locks you out of the entire computer), block lists, scheduled blocks, and the famous "no way to disable mid-session" mode that requires a randomly-generated string from a sister page to unlock.
Pros: Genuinely hard to bypass. One-time pricing. The implementation is more "system-level" than most competitors — they go to real lengths to defeat the workarounds (DNS, hosts file, browser extensions, etc.) that defeat softer blockers.
Cons: No iPhone support, so it can't help with the actual phone problem. The UI is dated. The "you can't escape" framing feels punitive for some users.
Pick this if: you've already tried softer tools and bypassed them. Cold Turkey is the maximum-security option.
Opal
What it is: An iPhone-first app blocker with social-accountability features (groups, streaks, friend visibility). Has a Mac companion via web for stats but the blocking is iPhone-side.
Pros: Targets the actual problem (the phone). Polished UI. The social/accountability framing actually helps some people stick with it.
Cons: Subscription. The "social" piece is great for some, claustrophobic for others. Depends on iOS Screen Time APIs, which means Apple's choices constrain what Opal can do — and they're slow with new APIs.
Pick this if: your problem is iPhone scrolling and you respond well to streaks and social pressure.
One Sec
What it is: Instead of blocking apps, One Sec inserts a forced "deep breath" delay (default ~10 seconds) when you try to open one. The friction is the point.
Pros: The pause-and-breathe pattern is well-supported by behavioral research — most compulsive opens are autopilot, and a 10-second interruption is enough to break the autopilot a lot of the time. Has a Mac version too.
Cons: Doesn't actually stop you — if you really want to open the app, you'll wait the 10 seconds. So it's a nudge, not a wall. Subscription.
Pick this if: you want to be reminded, not handcuffed. The data they publish (own + independent) suggests this is the right intensity for most casual users.
Apple Focus modes
What it is: Built into macOS and iOS. Custom Focus modes let you allow only specific contacts/apps to send notifications, hide app icons, swap home screen pages, etc. Syncs across devices.
Pros: Free. Already on your devices. Surprisingly capable now (Filters per-app, Focus + Stage Manager combos, etc.). Cross-device by default.
Cons: Notification-focused, not block-focused. You can still open the app — Focus just won't ping you. Requires non-trivial setup; most people configure it once and forget.
Pick this if: your problem is interruptions, not compulsive opens. Try this before paying for anything else.
PhoneDown
What it is: Mac-only menu-bar app that uses your laptop camera to detect when you reach for your phone, then ticks up a counter. No popup, no audio, no shame text — just a small number that grows in your menu bar. phonedown.io.
Pros: Targets the gesture, not the app. Doesn't run on the phone — so unlike app blockers, you can't disable it from inside the rabbit hole. On-device camera processing (Apple Vision framework); no frames are uploaded or stored. $9 one-time, no subscription. Lives in the menu bar with no Dock icon and no window.
Cons: Mac-only. Needs the lid open and the camera unobstructed. Doesn't actually block anything — you have to care about the count for it to work. (For most people, that's enough; for some, it isn't.)
Pick this if: your specific problem is "I'm at my Mac and my phone is right there and I keep grabbing it." That's the situation it's built for, and nothing else on this list addresses it directly.
Decision guide
- Just need to stop interruptions while working? Apple Focus, free, set it up tonight.
- Compulsively opening Twitter/Reddit/etc. on the laptop? Cold Turkey if you've already tried softer things; One Sec if this is your first attempt.
- Compulsively opening Instagram/TikTok on the phone? Opal, or Apple Screen Time as the free baseline.
- Want everything blocked everywhere on a schedule? Freedom.
- Phone-on-the-desk problem? PhoneDown, $9, mine.
None of these are silver bullets. The best one is the one you'll actually leave installed for more than a week. Pick the cheapest plausible match, try it, and if it's not landing, swap.
