Jomo vs Opal: Which Is Better?

Jomo vs Opal comes down to a simple tradeoff: a tighter, cheaper iOS and Mac tool, or broader platform coverage with heavier features behind a pricier tier.

Quick Verdict

• Choose Jomo if: You're on iOS or Mac only, want a clean interface, and don't need Android or Chrome coverage
• Choose Opal if: You want the widest platform reach (iOS, Mac, Chrome, Android) and are willing to pay for the anti-bypass settings that make Deep Focus hard to get around

Opal vs Jomo: Same Two Apps, Reverse Order

If your search led you here as "opal vs jomo" instead, this is still the right page. Both apps use Apple's Screen Time API on iOS, and the comparison below covers the same feature set regardless of which name came first in your search.

Jomo in 30 Seconds

Jomo, made by Jomo SAS, runs on iOS (iPhone and iPad) and Mac. It uses Apple's Screen Time API to block apps and websites by schedule, usage limit, or "until you take an action." Category-based blocking covers groups like Social Media, Games, and Shopping. Its Strict Mode advertises a lockout for a set duration with no early opt-out, plus an anti-uninstall protection while active. It's freemium, with a Jomo Plus subscription unlocking unlimited blocking, Strict Mode, and app exclusions.

Opal in 30 Seconds

Opal, from Opal OS Corporation, runs on iOS (iPhone and iPad), Mac, Chrome (via browser extension), and Android, though the Android version is described as having ads on its free tier and weaker blocking than iOS due to platform limitations. Its "Deep Focus" mode cannot be cancelled once a timer is set, and optional Screen Time Passcode and App Uninstall Protection settings can prevent disabling or deleting the app mid-session. Without those settings turned on, Opal's own help center acknowledges the app can be disabled in one step through iOS Settings. It's freemium, with the free tier excluding Deep Focus mode.

Best for	iOS/Mac users who want a clean, focused blocker	Users who want the widest device coverage and AI-driven usage analytics

Key Differences

The jomo vs opal gap shows up most clearly in how each app handles the moment you actually try to get around it.

Strict Mode Reliability

Jomo's Strict Mode is advertised as a lockout with no early opt-out and an anti-uninstall protection, but Jomo maintains a dedicated troubleshooting article acknowledging that blocking "doesn't turn off when it's supposed to" and similar engagement failures happen often enough to need documentation. Opal's Deep Focus is non-cancellable once started, and with its Screen Time Passcode and App Uninstall Protection settings enabled, it's harder to defeat than Jomo's default configuration, though Opal's own help center confirms it can be turned off in one step if those extra settings aren't configured.

Winner: Opal, but only once its optional anti-bypass settings are actually turned on, which sits behind the same tier that also unlocks Deep Focus itself.

Platform Reach

Jomo covers iOS and Mac only. Opal adds a Chrome browser extension and an Android app, even if that Android version is described as weaker, with ads on the free tier and platform limitations reducing blocking strength.

Winner: Opal, for anyone who needs blocking across more than an iPhone and a Mac.

Cost of Full Protection

A published review found Jomo's free version too limited, with scheduled sessions, advanced groupings, and usage insights all paywalled, and noted Jomo can't block Safari at the granular level native Apple tools allow. Opal's independent review calls its Pro price steep for a screen time blocker and says the free plan is "almost useless" since it excludes Deep Focus mode entirely, the one feature that makes the app hard to bypass.

Winner: Jomo, on price. Its entry-level paid tier is the cheaper way to unlock a working Strict Mode compared to Opal's Pro pricing.

Honest Concessions

Jomo's reliability problems are real and self-documented: its own help center's troubleshooting article for blocking failures states "we understand your frustration and share it," which is a rare level of candor but also a real product weakness.

Opal has its own documented issues: a user reported the app blocked apps they hadn't selected and struggled for three days to get a refund after an unwanted renewal, and an independent review notes that even with Deep Focus enabled, users can still delete the app, change phone settings, or find workarounds, concluding the software "can be bypassed by the person it is trying to help."

Which Should You Choose?

For most people, jomo vs opal is decided by two questions: which platforms do you actually need covered, and how much are you willing to pay for the strongest anti-bypass setting.

You only use an iPhone and a Mac: Jomo. No reason to pay for cross-platform coverage you won't use.

You need Android or browser coverage too: Opal, despite the weaker Android experience described in independent reviews.

You want the strongest anti-bypass setup regardless of cost: Opal, with Screen Time Passcode and App Uninstall Protection both enabled.

Budget is the deciding factor: Jomo's tiers are generally the cheaper path to a working Strict Mode. Compare current pricing directly on jomo.so and opalapp.com since both change over time.

You want AI-driven usage analytics: Opal's Focus Score and Focus Report features go deeper than Jomo's on-device tracking and journaling.

Frequently Asked Questions

Does Jomo work on Android? No. Jomo is iOS and Mac only. If you need Android coverage, Opal is the option between these two, though its Android version has ads on the free tier and blocking described as less robust than iOS.

Is Opal's Deep Focus really uncancellable? Once a Deep Focus session starts, it can't be stopped from within the app before the timer ends. But without Opal's optional Screen Time Passcode and App Uninstall Protection settings turned on, the app itself can still be disabled through iOS Settings, according to Opal's own help documentation.

Why does Jomo's blocking sometimes fail to turn on or off? Per Jomo's own troubleshooting article, this is usually caused by conflicts with other Screen Time apps, Low Power Mode, or an outdated iOS or app version. It's a documented, ongoing issue rather than a one-off bug report.

Jomo vs Opal: which one has better analytics? Opal. Its AI-driven Focus Score and Focus Report analyze usage patterns in more depth than Jomo's on-device screen time tracking and journaling.

Is there a faith-based alternative to Jomo or Opal? Neither app has a spiritual dimension; both are general-purpose productivity blockers. FaithLock uses the same Screen Time API to block apps on iOS, but the way back in is answering a Bible quiz question rather than waiting out a timer or a Strict Mode lockout. See the FaithLock vs Opal comparison for a fuller look at that specific matchup, or the best Christian app blocker guide for other options.
