DMOnly vs Opal: Which iPhone App Blocker Actually Works?

Opal and DMOnly are both built on Apple's Screen Time framework, both promise to help you put your phone down — but they take almost opposite approaches to getting you there. This is an honest, feature-by-feature comparison from someone who built one of them (DMOnly) and uses both. No fluff, no fake "we win everything" verdict.

The core difference: philosophy

Most app blockers, Opal included, work like a parental control: you decide what to block, when, and for how long. The default state is access; you carve out periods of blocking around your day.

DMOnly is built around the opposite mental model. Your distracting apps are locked all day, every day, by default. To use Instagram or TikTok, you actively open a 15-minute window. When the window closes, the apps auto-lock again. You get a limited number of windows per day (2 on free, 10 on Pro). That's the whole product.

Opal asks: "When do you want to be blocked?"
DMOnly asks: "When do you want to be unblocked?"

This isn't a marketing framing — it's a real mechanical difference that shapes everything downstream: which mistakes are easy to make, what the friction feels like, who the app fits.

Blocking mechanic, head-to-head

How Opal blocks

Opal gives you three tools:

• Daily limits — cap a specific app to N minutes/day (e.g., 30 min of Instagram)
• Scheduled blocks — block apps during set hours (e.g., social media off 6 PM to midnight)
• Focus sessions — start a manual timer; apps are blocked for the duration

In the free tier, you can stop any session early. The paid Deep Focus mode prevents early termination — that's the main gate behind the $99.99/year paywall. The mechanics are flexible, and if you like configuring things, the surface area is rewarding.

How DMOnly blocks

DMOnly has one mechanic: your apps are always locked, except inside a 15-minute window. You tap "Open a window," the apps unlock, the timer starts. When it hits zero, the apps lock again — automatically, with no opt-out screen.

The constraint is your daily quota. Free users get 2 windows per day (30 minutes total). Pro users get 10 (2.5 hours). When you've used them all, you're done for the day. There is no "10 more minutes" prompt, no session extension, no overage. The day resets at midnight.

Which one is "harder"?

Honest answer: both can be bypassed if you really want to. Both rely on Apple's Screen Time API, which means anyone determined enough can uninstall the app, disable Screen Time in Settings, or use the same blocked apps on the web. Neither blocker is "foolproof" — Apple doesn't give third-party apps that level of system control on iOS.

But there's a meaningful difference in everyday friction:

• Opal's friction is per-session. You decide to start a session, you decide when to stop. The decision happens many times a day. Decision fatigue is the failure mode.
• DMOnly's friction is per-day. You can't add more windows once they're spent. The decision happens once (at the moment you spend a window). The failure mode is uninstalling the app entirely — a much bigger commitment.

Opal Deep Focus addresses this by locking the session for its duration. DMOnly's quota addresses it by capping the total. They solve the same problem from different ends.

Analytics, rewards, and "feel"

This is where Opal wins clearly. It's an Apple Design Award winner; the interface is polished, the gem-based reward system ("Opal Score," "Devoted Gem at 1,000 focus hours") is genuinely well-executed, and the analytics dashboards are deep. If you enjoy looking at charts of your own behavior, Opal feels rewarding.

DMOnly is minimal by design. The home screen shows a countdown if a window is active, your remaining quota for the day, and a simple weekly bar chart. There are no badges, no leaderboards, no streaks-to-protect. The thinking is that gamifying focus turns the blocker itself into something to engage with — and engagement is exactly what we're trying to spend less of.

Reasonable people can disagree on which is better. If seeing your progress motivates you, Opal will feel rich. If you've already learned that you'll game any system that has points in it, DMOnly's flatness is the feature, not a missing one.

Platforms and ecosystem

Platform	DMOnly	Opal
iPhone	Yes	Yes
iPad	Not yet	Yes
macOS	No	Yes
Android	No	Yes
Web / Chrome extension	No	No

If you bounce between iPhone, Mac, and a work laptop and want consistent blocking across all of them, Opal is the better fit today. DMOnly is iPhone-first by design — most distraction problems originate on the phone, and supporting fewer platforms means a smaller, simpler product. That trade-off may not be the right one for you.

Pricing, honestly

Opal is the most expensive mainstream app blocker on the iOS App Store:

• Monthly: $8.29
• Annual: $99.99
• Lifetime: $399

For that money you get a polished product across multiple platforms with deep features. It's not unreasonable — Opal is a real company with a real team. But the price has become a common complaint in reviews; if you found this comparison because you searched "Opal alternative cheaper," you're not alone.

DMOnly's pricing:

• Monthly: $4.99
• Annual: $39.99 (saves about 33%)
• Lifetime: none

DMOnly is roughly 40% of Opal's annual price. You're paying less because you're getting a narrower product — one platform, one core mechanic, no multi-device sync, no team or family features.

Who should pick which

Pick Opal if:

• You want cross-device blocking (iPhone + Mac + iPad)
• You enjoy data, charts, and reward systems
• Your distraction problem is mostly about scheduling — you want apps blocked during work hours, unblocked otherwise
• You've never used an app blocker before and want the polished onboarding
• $100/year doesn't feel like a lot relative to your income

Pick DMOnly if:

• You've tried Opal, Freedom, ScreenZen, etc., and bypassed all of them
• Your problem isn't scheduling — it's that you reach for your phone constantly, all day
• You want a hard daily cap, not a flexible system you'll game
• You're iPhone-only and don't need Mac/Android coverage
• You prefer paying $40/year over $100/year for narrower scope
• You believe gamifying focus is part of the problem, not the solution

Final verdict

Neither app is "better" universally — they're built for different users with different failure modes. Opal is the right answer if your relationship with your phone is fixable with smarter rules. DMOnly is the right answer if you've concluded that no rule system survives contact with a tired Tuesday night.

The real test for either is the same: can you go three days using only what the app allows? If yes, it's working. If no, it doesn't matter how polished the dashboard is — you've already found the workaround. We'd rather you find that out on a 7-day free trial than after spending $99.

Frequently asked questions

Is DMOnly a clone of Opal?

No. The default state is opposite (locked vs. unlocked), the pricing is different, the mechanic is different. We do use the same underlying Apple Screen Time API — every iOS app blocker does, because Apple doesn't allow another way.

Can I use both?

Technically yes — they'll both apply Screen Time restrictions independently. In practice, you'll be confused about why something is blocked at any moment. Pick one.

Does DMOnly work on Android?

Not today. Android's permission model is different from iOS's, and we wanted to ship a focused iPhone product before splitting attention. If Android matters to you, Opal supports it.

What about Freedom, ScreenZen, Jomo, One Sec?

Full comparisons: DMOnly vs Freedom, DMOnly vs One Sec, DMOnly vs ScreenZen, DMOnly vs Jomo. Or see our roundup of the 7 best iPhone app blockers.

What if I want a lifetime deal?

DMOnly doesn't offer one yet. If the math matters: Opal's $399 lifetime is roughly 4 years of DMOnly Pro at the annual rate.

I bought Opal and want to switch — can I get a refund?

Apple handles all App Store refunds, not us or Opal. You can request one at reportaproblem.apple.com — Apple's policy is usually generous within 14 days, less generous after.
