Opal vs ScreenZen in 2026: Is Opal's $99.99 a Year Worth It Over Free?

Opal Pro is $99.99 a year; ScreenZen is free and donation-supported. Here's what each one blocks, how each stops you cheating, and which to install first.

Prices checked Oct 15, 2026 on Opal’s pricing page and ScreenZen’s site (Opal student and website details and ScreenZen’s Halo price checked Oct 17, 2026; platforms and blocking features checked Oct 20, 2026). Everything is linked under Sources. No affiliate links on this page (how we work).

Here’s the short answer: install ScreenZen first. It’s free, it runs on iOS, macOS, Windows and Android, and it has a lock mode that its own site says can stop you uninstalling it. Pay for Opal Pro only if you’ve already tried a free blocker, you keep talking your way past it, and you want the one switch Opal sells as “No way out.”

We haven’t tested Opal or ScreenZen. Everything below comes from their own sites, help pages and store listings.

TL;DR by situation

You want free: ScreenZen. “ScreenZen is completely free,” with optional donations. Opal Free gives you 1 rule.
You’re on iPhone: both work. Opal’s website blocking is most reliable in Safari, per its own help docs. Start with ScreenZen; move to Opal Pro if you need Hard Mode.
You’re on Android: both list Android. ScreenZen blocks websites on Android through Accessibility permissions. Opal’s help docs we read don’t cover Android website blocking.
You always cheat: Opal Pro’s Hard Mode, or skip software you control and give the key to someone else (more on that below).

If you want the wider field, our Opal alternatives page has eight options and the best screen time app list goes broader. This page is the head-to-head.

Opal’s Free plan is “forever $0” with 1 rule: a schedule, a time limit or an open limit. Pro is $19.99 a month, $99.99 a year (shown as $8.29 a month, with a free week to start), or $399 once. Twelve months on the monthly plan is $239.88, so if you’re paying, the yearly plan is the obvious one.

And yes, the lifetime plan to help you use your phone less costs $399. Gollum would call it “my precious” and mean the phone, not the subscription.

ScreenZen’s FAQ answers the money question directly: “Do I have to pay to use ScreenZen? No. ScreenZen is completely free. You can always support the project with a small donation.” Its Google Play listing shows in-app purchases of $4.99–$19.99 per item (Oct 15, 2026). Those are donation items, not a plan price. The optional Halo device is $49 one-time, and the app stays free.

One Android wrinkle: Opal’s Google Play listing shows in-app purchases of $2.99–$79.99 per item (Oct 15, 2026), which tops out below the $99.99 yearly price on Opal’s site. So the Android price may differ from the website. Check current price in the app before you subscribe.

What each one blocks

Platforms (checked Oct 20, 2026). ScreenZen calls itself “the only free screen time app for iOS, macOS, Windows and Android.” Opal says it’s “Available on iPhone, Mac and Android.” So ScreenZen covers a Windows PC and Opal doesn’t list one.

Apps. Both block apps. ScreenZen’s site: “You choose which apps and websites to block,” and “You decide when to limit or fully block apps using simple schedules or daily limits.” Opal Free gives you one rule; Pro adds unlimited rules, Advanced Timers, “Allow Only” and Opal Score with history.

Websites. Both say yes, with footnotes.

Opal: blocks apps and websites. Its help docs say website blocking is reliable in Safari on iOS but often not in third-party browsers, and the Mac app supports Chrome, Safari, Opera, Edge, Brave and Arc (checked Oct 17, 2026).
ScreenZen: its Play listing says “Pause before opening apps or websites” and “ScreenZen uses Accessibility permissions to block websites” on Android (checked Oct 20, 2026).

If you live in Chrome on an iPhone, Opal’s own docs are telling you something. Listen to them.

How each one stops you cheating

This is the real comparison. Nobody downloads a blocker because they lack willpower in theory. They download it because at 1 AM, life, uh, finds a way. Jeff Goldblum was talking about dinosaurs. He could have been talking about your thumb finding Instagram.

ScreenZen: friction first, lock if you want it. Its Play listing describes the tools:

“Pause before opening apps or websites: Take a moment before launching a distracting app. The wait time can increase with each use.”
“Interrupt your scrolling: Limit your time on distracting apps to short bursts.”
“Set usage goals: Define daily limits per app — and optionally block access when you hit your target.”
“Mindful prompts before opening apps: Messages like ‘Is this important?’”

Its homepage adds: “There’s a lock mode that protects against common loopholes. You can prevent uninstalling and make it much harder to bypass limits.” ScreenZen doesn’t publish the default wait length or a numeric open limit, so I won’t quote one.

Opal: rules, then Hard Mode on Pro. Opal lists Hard Mode as a Pro feature and describes it in one line: “No way out. You can’t turn Opal off.” That’s the whole public spec. Opal’s help center doesn’t publish Hard Mode mechanics beyond it.

Opal’s “how do I make Opal foolproof” article (checked Oct 20, 2026) describes something different: setting rules to “No Unblocks Allowed” or “No Resets Allowed”. A running “No unblocks allowed” schedule can only be edited when it ends; “otherwise, you MUST use your Emergency Pass to exit.” The same article lists iOS settings to close loopholes: a Screen Time passcode, an Opal PIN, App Uninstall Protection, hiding Opal from the Home Screen and locking Screen Time access.

So the honest difference: ScreenZen’s free lock mode makes cheating “much harder”, by its own wording. Opal’s paid Hard Mode says “No way out.” Neither company’s page gives you test results, and we don’t have any either.

Opal puts Hard Mode, the one feature built for people who cheat, behind Pro, and the cheapest way in without a year’s commitment is $19.99 a month. The people who most need “No way out” are exactly the people who’ll cancel a monthly plan at 1 AM. It’s Tony Soprano booking therapy and walking out of every session.

When neither holds: a lock someone else controls

Here’s the uncomfortable bit. Every setting above is a setting you control, so the off switch is always one settings screen away. Our piece on why app blockers don’t work goes into why. One fix is a commitment device where someone else holds the key.

On Android, that’s what FriendLock does. A friend holds the unlock key: they approve or deny your request in the app, or read you a 6-digit code over a call. It can block just Reels, YouTube Shorts or Snapchat Spotlight so WhatsApp and maps keep working, it can block websites, and it alerts your friend if you try to uninstall or bypass it. The free plan blocks up to 3 apps and may show ads on in-app screens; Pro isn’t priced on its Play listing, so check current price in the app (Google Play, checked Oct 15, 2026).

It’s Android only. And it isn’t tamper-proof: the alert tells your friend, it doesn’t stop a determined phone owner. That’s the point. Cheating now means a conversation.

Disclosure: the team behind this site has a stake in FriendLock.

More Android options are in our best app blocker for Android list. If you’d rather lock the phone with a physical object, see Brick alternatives.

Here’s what I’d do

Install ScreenZen tonight. It’s free, it covers more platforms, and its pause-plus-limits setup is enough for a lot of people. Turn on its lock mode on day one, not after the first relapse.

Give it two weeks. If you keep waiting out the pause and opening the app anyway, then pay for Opal Pro, and pay yearly ($99.99), not monthly ($19.99). Student? Ask for the up-to-50% discount first. Skip lifetime unless you’re sure; $399 is a lot of money to bet on future you.

On Android, and you know you’ll cheat on any lock you control? Hand the key to a friend instead.

If a phone-side app keeps losing to your thumbs, Brick vs Opal covers the hardware route.
