I get asked about Opal alternatives often enough that I've started keeping notes. It says something about the category that so many people are actively looking for a replacement rather than just cancelling and going without, which suggests the underlying need, some kind of structure around phone use, is real even when a particular app isn't the right fit for a particular person. Most of the "best alternatives" lists online are written by people who haven't used the apps they're ranking, so here's one from someone who has, including the app I built. I'm not pretending to be neutral about BRNIQ, but I've tried to give it exactly the same treatment as everything else here: what it does, what's genuinely good about it, and where it falls short.
People usually end up looking for an Opal alternative for one of two reasons. Either the pure blocking model isn't sticking (the schedule gets skipped, the strict mode gets worked around, the habit comes back within a few weeks), or they simply want a different flavour of the same idea, a different price point, a different tone, a mechanic that asks something of them rather than just waiting them out. Worth knowing which camp you're in before picking from this list, because the right alternative depends on which problem you're actually trying to solve.
Opal
Opal is the app most people are looking to replace or supplement when they land on a list like this, so it's worth a quick word on what it actually does. Scheduled focus sessions, app blocking during those sessions, and a polished, well-designed interface that's held up over several years in the category. If you want a clean, mature blocking tool for dedicated focus time, it does that job properly.
The limitation is inherent to the model rather than the execution. It restricts. There's nothing to do during the blocked window except wait it out or break your own schedule. For some people that's exactly enough. For others, the block itself becomes the thing they resent.
Standout strength: maturity and polish. This is a well-worn product, not a beta. Honest limitation: nothing happens during the block except waiting, and waiting is exactly the skill most people struggle with in the first place.
one sec
one sec's approach is friction instead of a hard block. Try to open a distracting app and you get a short breathing exercise before you're asked whether you still want to go in. It's lightweight, quick to set up, and genuinely useful for habits that are more autopilot than compulsion.
The honest limitation is that friction fades. Once you've done the breathing pause a hundred times, you can get through it without really re-engaging with the choice. It's a great starting point for mild scrolling habits, less effective once a habit has become well worn.
Standout strength: it's the lowest-friction way to start, literally and in terms of setup effort. Honest limitation: the pause is passive, and passive interventions are the easiest ones to adapt around.
BePresent
BePresent takes a scheduling and streaks approach, similar in spirit to Opal but with a softer, more "intentions" focused framing and a following built largely on social platforms. You set sessions, block apps during them, and build a streak of days you've stuck to your own limits.
It's a genuinely pleasant app to use if you respond well to gentle accountability and don't need much more than a nudge and a visual streak to stay on track. The limitation is the same one that applies to most scheduling apps: nothing happens during the blocked time except waiting, and streaks alone don't do much for people who need a stronger reason to stay out of an app in the moment they're tempted.
Standout strength: the community and accountability layer gives scheduling apps a social pull that a solo blocker doesn't have. Honest limitation: streaks measure whether you showed up, not whether the block is actually working on your underlying habit.
Quiz Screen
Quiz Screen is the closest thing to BRNIQ on this list conceptually. It blocks apps until you answer a quiz question, so the earning mechanic is already there, which is worth crediting. Where it tends to fall short, based on how people describe it, is depth. The questions are often short trivia-style prompts rather than a structured curriculum, which makes the gate quick to get through but light on anything you'll remember afterward or use for actual revision.
If you like the earn-to-unlock idea but don't need the content to be substantial, it's a reasonable, simple option.
Standout strength: it proves the earn-to-unlock mechanic works as a category, and it's a low-commitment way to try that idea out. Honest limitation: the questions are generally too shallow to double as anything you'd call learning.
BRNIQ
Same mechanic as Quiz Screen in spirit, try to open a blocked app and you're gated behind a learning session, but built around actual content depth rather than one-off trivia. Five cards on a topic you picked, then a three-question quiz, two right to unlock your apps for up to two hours (the full walkthrough is in how BRNIQ works if you want the mechanics in detail). The library runs to 100,000+ cards across 200+ topics, including GCSE and A-Level revision subjects, University Foundations material, and nine languages, so the five minutes you spend unlocking can double as actual study time, not just a hoop to jump through.
Standout strength: the content is deep enough to double as actual revision or language practice, not just a hoop to jump through. Honest limitation: it's iOS only right now, Android is planned but not live, and if you want a completely dead-end block with zero alternative activity, that's not what this is built for. It also asks more of you per unlock than a quiz app or a breathing pause does, five minutes instead of a few seconds, which is a feature if you want the gate to mean something and a downside if you just want the fastest possible way back into your apps.
So which one
If you want scheduled focus sessions and nothing more, Opal or BePresent will serve you well, and the choice between them mostly comes down to which interface and framing you prefer. If your habit is mild and autopilot-driven, one sec's friction might be enough on its own. If you like the idea of earning your way back in but don't need depth, Quiz Screen is a lighter version of that idea. If you want the gate to actually produce something, revision, vocabulary, real knowledge, alongside unlocking your apps, that's the gap BRNIQ is built to fill. The reasoning behind why a reward-based gate outlasts a restriction-based one is laid out properly in why earning your scroll beats blocking it, if you want the underlying argument rather than just the app-by-app comparison.
