How Blok and Opal block apps differently

Opal uses a Software-only blocking system. When you start a focus session, Opal routes your internet traffic through a local VPN that blocks connections to specific apps and websites. This is a common approach used by many screen time apps.

Blok uses Apple's Family Controls / Screen Time API on iOS and built-in device restrictions on Android. This is the same system-level framework that powers parental controls. When Blok activates, the blocked apps literally cannot be opened.

The difference matters more than you'd think. Software-only solutions can be disabled through settings with minimal friction. System-level blocking combined with a physical device creates a fundamentally different barrier. We wrote about why physical phone blockers beat software in depth.

Blok adds another layer: a physical NFC device. To start or stop blocking, you tap your phone to a card, keychain, or magnet. If that device is in another room, you have to physically get up to change anything.

Can you bypass Blok vs Opal?

Let's be honest about this, because it's the most important question.

Opal: Yes, you can bypass it. Because Opal is software-only, there's always a path back to your apps through your phone's settings. Opal has added friction to this process (warnings, confirmations), but at the end of the day, you're fighting software with software. Multiple Reddit discussions confirm that users find ways around it when the urge is strong enough.

Blok: Much harder to bypass. Because Blok uses Apple's Screen Time API at the system level, there's no simple toggle. And because activation requires a physical NFC tap, you need the actual device in hand. Leave your Blok card at home and you genuinely can't turn it off.

Neither is 100% unbypassable (a factory reset will beat anything), but Blok creates significantly more friction between the impulse to check your phone and actually doing it.

Where Opal wins over Blok

Credit where it's due. Opal does some things better:

Real friction beats willpower every time

Blok's NFC card creates a physical barrier between you and your distractions.

Get Blok
  • Screen time analytics: Opal provides detailed breakdowns of your screen time, app usage patterns, and trends over time. If you're data-driven and want to understand your habits before changing them, Opal's analytics are genuinely useful.
  • No physical device needed: Everything is in the app. No card to carry, no keychain to pair. If you want simplicity, Opal is easier to get started with.
  • App design: Opal has a polished, well-designed interface with nice onboarding and clear session management.
  • Community features: Opal has group sessions where you can focus with friends or coworkers.

If you're someone who responds well to data and gentle nudges, and you trust yourself not to toggle off the VPN, Opal is a solid choice.

Where Blok wins as an Opal alternative

Here's where Blok pulls ahead:

  • Can't bypass it: System-level blocking + physical NFC device = the highest friction of any consumer app blocker we've seen.
  • Physical activation: The NFC tap creates a ritual around focus. It's not just pressing a button. It's a deliberate physical action that signals a mindset shift.
  • Android support: Opal is iOS only. Blok works on both iOS and Android.
  • Price: At $59.99/yr, Blok is about 40% cheaper than Opal's ~$99/yr subscription.
  • 3 preset modes: Work, Sleep, and Focus modes with separate block/allow lists. Set up once, tap to switch.
  • Scheduled blocking: Automatically activate modes at set times. Sleep mode at 10pm, Work mode at 9am, no manual action needed.
  • Streaks and Blok World: Track your consistency and see how you compare to other users on the social leaderboard.

The core difference: Opal trusts your willpower. Blok doesn't. And research on self-control suggests that designing your environment beats relying on willpower almost every time.

Pricing: Blok vs Opal

Opal pricing starts around $99/yr for their premium plan. They offer a free tier with limited features, but the full blocking capabilities require a paid subscription.

Blok is $59.99/yr or $9.99/mo for full app access. Physical NFC devices (card, keychain, or magnet) are sold separately through the Blok store.

On a yearly basis, Blok saves you roughly $40 compared to Opal, while offering stronger blocking that's harder to bypass.

Who should use Opal vs Blok?

Choose Opal if:

  • You mainly want screen time analytics and usage insights
  • You prefer an all-software solution with no physical device
  • You're disciplined enough not to bypass a VPN-based blocker
