The 7 Best iPhone App Blockers in 2026
Most "best app blockers" lists are SEO landing pages that recommend whichever app the author has an affiliate deal with. This is not that — though we should say up front: we make one of these apps (DMOnly). We'll tell you exactly when not to pick it.
We tested seven serious options used by actual people, including Apple's own free tool. Each entry covers what the app does, how its blocking mechanic works, what it costs, and — most usefully — who it's the wrong choice for.
TL;DR — pick the one that matches your problem
- You want it free: ScreenZen or Apple Screen Time
- You want polish + cross-device: Opal
- You want it across iPhone, Mac, and laptop: Freedom
- You break "scheduled blocks" by overriding them: DMOnly (hard daily cap removes the override loophole)
- Your problem is reflexive opens, not duration: One Sec
- You want it to feel like a wellness coach: Jomo

| App | Mechanic | Price (annual) | Platforms |
|---|---|---|---|
| DMOnly | Default-off, 15-min windows, daily quota | $39.99 | iPhone |
| Opal | Schedules, limits, Focus sessions, Deep Focus | $99.99 (or $399 lifetime) | iPhone, iPad, Mac, Android |
| One Sec | Intentional pause before opening apps | $17.99 (or $23.99 lifetime) | iPhone, Android |

| Apple Screen Time | Built-in OS limits & app limits | Free | iPhone, iPad, Mac |
1. DMOnly
DMOnly's mechanic is unusual: your distracting apps are locked by default, all day. When you really need them, you open a 15-minute window. The apps unlock, the timer counts down, and when it hits zero they auto-lock again. You get a fixed number of windows per day (2 on free, 10 on Pro). Once spent, you're done until midnight.
The point of this design is to remove the failure mode that kills most blockers — the "10 more minutes" loophole. There's no extension. There's no override. When your quota is gone, only uninstalling the app gets around it, which is a much bigger barrier than dismissing a dialog.
Pros
- Hard daily cap removes "just one more session"
- Simple — one mechanic, nothing to configure wrong
- Among the cheapest paid options ($40/yr)
- 15-minute window length is short enough to stay intentional
Cons
- iPhone only — no Mac, iPad, or Android
- No analytics dashboards or gamification
- No flexible scheduling (it's all-day-every-day)
- Newer than most competitors — smaller review history
Don't pick DMOnly if: your problem is at the laptop, not the phone. Or if you want flexible scheduling ("blocked during work hours, unblocked after"). The mechanic is intentionally rigid.
2. Opal
Opal is the most polished app in this list. It won an Apple Design Award. The interface is rewarding to use, and the gamification (Opal Score, Focus Gems, leaderboards) is genuinely well-executed. You get three blocking tools — daily limits, scheduled blocks, and manual focus sessions — and a "Deep Focus" mode that prevents you from ending a session early.
The big complaint, repeated in many reviews, is the price: $99.99/year is the most expensive option here by a significant margin. For your money you get a wide feature set and multi-platform support that none of the cheaper options match.
Pros
- Deep feature set: scheduling, limits, sessions, Deep Focus
- Cross-device (phone, Mac, Android)
- Polished UI; Apple Design Award winner
- Detailed analytics and rewards system
Cons
- Most expensive paid option at $99.99/year
- Free tier is heavily limited (1 recurring session)
- Lots to configure — easy to set up wrong
- Standard mode is easy to bypass; you need Deep Focus (Pro) for real friction
Don't pick Opal if: $100/year feels like a lot, or you've already noticed that you can dismiss its sessions when you want to. The Deep Focus mode is the version of Opal that actually works — and it's behind the paywall.
3. One Sec
One Sec attacks a different angle: it doesn't block anything, it just adds a pause before each opening. You tap Instagram, a 10-second breathing animation appears, and you decide whether to continue. It's the only app in this list with peer-reviewed evidence behind it — a 2023 study published in PNAS found a 57% reduction in app usage.
The mechanic is gentle, which is both its strength and its weakness. If you're a reflexive opener — you pick up your phone, swipe to Instagram, and only then realize you didn't actually decide to — the pause works well. If you're someone who can decide to scroll for an hour and means it, the 10 seconds won't slow you down.
Pros
- Cheap, especially the $23.99 lifetime option
- Backed by published research (PNAS, 2023)
- Gentle — doesn't feel like a punishment
- Works without confrontation, so you keep using it
Cons
- Doesn't actually block — you can always continue past the pause
- Limited free tier (only a few apps)
- If your problem is duration (you scroll for 90 minutes), this won't fix it
Don't pick One Sec if: you've tried "intentional pause" apps before and concluded that you just hit "continue" every time without thinking. The mechanic depends on your willingness to actually pause.
4. ScreenZen
ScreenZen is the rare app blocker that genuinely doesn't push you toward a subscription. The core product — configurable per-app delays and intention prompts — is free, with no aggressive paywall behind it. There's a paid tier for fancier features, but you can use the app indefinitely without it.
The mechanic sits between One Sec (gentle pause) and Opal (hard blocks). You add friction — a 5-second wait, a question prompt — between you and the distracting app. It works for the same kind of user One Sec works for, but at zero cost.
Pros
- Genuinely free, not "free trial" free
- Simple to set up
- Reasonable friction without feeling punitive
- Good first try before paying for anything
Cons
- UI less polished than paid competitors
- Same fundamental weakness as One Sec — you can always continue
- Smaller team; updates can be slower
Don't pick ScreenZen if: you've already tried delays and pauses and need stronger constraints.
5. Jomo
Jomo positions itself as more of a digital wellbeing companion than a pure blocker. It has a strong library of ready-to-use routine templates — "morning routine," "deep work block," "weekend reset" — that you can apply in a tap. The framing is friendlier, less prison-warden.
The blocking mechanic is competent — sessions, schedules, limits — without anything mechanically novel. What Jomo is really selling is the feel: a more emotionally intelligent take on the same problem Opal solves.
Pros
- Friendliest UX in this list
- Strong template library for common routines
- Generous free tier
- Cheaper annual than Opal ($29.99 vs $99.99)
Cons
- iPhone only
- The "wellness coach" voice isn't for everyone — some find it patronizing
- Mechanically similar to Opal but with fewer power-user features
Don't pick Jomo if: you find affirming wellness language annoying. The voice is part of the product.
6. Freedom
Freedom is the oldest player here and the only one that takes cross-device blocking seriously. Start a session and it applies simultaneously across your phone, your laptop, your work computer, and your browser. If your distraction problem is really a "stop checking Twitter on every device" problem, this is the only app on this list that actually solves it.
The trade-off: Freedom's iPhone-side experience is good but not as polished as Opal or Jomo. It's a desktop-first product extended to mobile.
Pros
- True cross-device blocking — no other option matches this
- Long track record and mature feature set
- Strict scheduling that works
Cons
- Expensive (~$107/year) for the iPhone-only user
- iPhone UI less polished than competitors
- Overkill if you only need phone blocking
Don't pick Freedom if: you only need to block on your phone. You'll be paying $100+/year for capability you won't use.
7. Apple Screen Time (built-in)
Before you pay for anything else, try this. Settings → Screen Time → App Limits lets you set daily time limits on individual apps or whole categories ("Social Networking," "Entertainment"). It's not as flexible as the paid apps — but it's free, it's already on your phone, and for some people it's enough.
The famous weakness: when you hit your limit, iOS lets you tap "Ignore Limit For Today" with no friction. You can disable Screen Time entirely with your passcode in about 4 seconds. Every paid blocker exists partly because Apple's version is too easy to bypass.
Pros
- Free, no install, already there
- System-level, not subject to App Store restrictions
- Works across iPhone, iPad, Mac with one Apple ID
Cons
- Trivial to bypass ("Ignore Limit For Today")
- No scheduling beyond "Downtime"
- No analytics worth looking at
Don't rely on Apple Screen Time alone if: you've already tried it and tapped "Ignore Limit" enough times to know it doesn't work for you. That's why this list exists.
How to pick one — a decision tree
If you're undecided, try this:
- Haven't tried Apple Screen Time? Start there. Free, and it's the right answer for maybe 30% of people who think they need a third-party blocker.
- Tried Screen Time and tap "Ignore Limit" daily? Skip the "gentle" tools. You need real friction.
- Distraction is across phone + laptop? Freedom is the only serious cross-device option.
- Want polish, can afford $100/yr? Opal.
- Want polish, want to spend less? Jomo or DMOnly, depending on whether you want flexible routines (Jomo) or a hard daily cap (DMOnly).
- Problem is reflexive opens, not duration? One Sec.
- Want to spend zero dollars first? ScreenZen.
What none of these will fix
All seven apps share the same fundamental limit: every iOS blocker uses Apple's Screen Time API, which means none of them can prevent you from uninstalling the app or disabling Screen Time in iPhone Settings. If you're determined to override your own choices, the OS doesn't give third-party apps the power to stop you.
The honest framing is: these apps make it marginally harder to do the impulsive thing. They don't make it impossible. The right blocker is the one whose friction matches the size of your impulse — too gentle and you walk through it; too strict and you uninstall it within a week.
Try DMOnly

What's the cheapest serious iPhone app blocker?
ScreenZen if you want truly free. Among paid options, One Sec's $17.99/year or $23.99 lifetime is the cheapest. DMOnly's $39.99/year is mid-range. Opal at $99.99/year and Freedom at ~$107/year are the most expensive.
Which has the strongest blocking?
By "strongest" we mean "hardest to bypass": DMOnly's daily quota and Opal's Deep Focus are the strictest mechanics on this list. Neither can stop you from uninstalling the app — no iOS blocker can — but both make it harder to game the system day-to-day.
Do any of these work with Apple Watch?
Not directly. The Screen Time API is iPhone/iPad/Mac. Apple Watch enforcement happens at the iCloud-Family level via Apple's Screen Time, not through third-party apps.
Are these blockers safe? Do they see my data?
Apple's FamilyControls / Screen Time API is privacy-preserving by design — third-party blockers can specify which apps to block, but they can't see what you do inside those apps, what you message, or who you message. Always read the privacy policy of whichever app you choose.
Is there an Android equivalent?
Yes — Opal, One Sec, ScreenZen, and Freedom all have Android versions. DMOnly and Jomo are iPhone only.
