Built for Android, not ported to it
Opal grew up on iPhone, where Screen Time APIs do the blocking. Appcognito uses Android's own capabilities, which are more powerful and let it block far more thoroughly.

Opal is a beautiful iPhone app with an Android edition that arrived later and does less. Appcognito was built for Android from the start, blocks at the network level, needs no account, and costs roughly a seventh of Opal's yearly price.
Opal made its name on iPhone, and that is not an accident of marketing. On iOS, screen time blocking runs through Apple's Screen Time and Managed Settings frameworks. Every iOS blocker uses them, they work the same way for everybody, and the difference between apps comes down to design, coaching and price. Opal competes on all three and wins a lot.
Android does not work like that. There is no single system framework everyone plugs into. Instead there are several lower-level capabilities, a local VPN for network filtering, usage access, overlays, device admin, and what a blocker can do depends entirely on how much of that it chooses to build. An app that grew up on iOS and added Android later tends to ship the subset that most resembles what it already had.
That is the gap this page is about. Not design, where Opal is excellent, but how much blocking actually happens on an Android phone, and what it costs you per year.
Same job, done more privately and for far less. Here is where Appcognito pulls ahead.
Opal grew up on iPhone, where Screen Time APIs do the blocking. Appcognito uses Android's own capabilities, which are more powerful and let it block far more thoroughly.
Opal's premium plan runs to roughly $99 every year. Appcognito is ₹2,499 / $39 once, for life. One Opal year against every year you will ever use this.
Opal has accounts, onboarding and a social layer. Appcognito has no login, no backend and no analytics SDK. Your usage data is not a product.
Not just a screen cover on a timer. Blocked sites fail in every browser, and an app's internet can be cut while the app still opens.

Opal is one of the best-designed apps in this category, full stop. Its onboarding is genuinely good at getting someone from 'I should use my phone less' to an actual working setup, the focus score makes progress legible, and the social accountability layer works for people who need other humans involved. On an iPhone, where Apple's Screen Time APIs do the heavy lifting anyway, it is an easy recommendation. This page is specifically about Android.
Opal's premium tier runs to roughly $99 a year. Appcognito Pro is $14 a year, or $39 once for life.
Put plainly: a single year of Opal costs two and a half times what Appcognito costs forever. Over three years it is about $297 against about $39. There is no version of this comparison where the difference is marginal. It is worth being clear about what the extra money buys on iOS: continuous product work, a coaching layer, and a social feature set. Whether that is worth seven times the price is a personal call. What is harder to defend is paying iPhone-tier pricing for the Android edition.
Appcognito runs a local VPN service. No traffic leaves the device and there is no server involved; it is simply the Android API for filtering your own traffic on your own phone. That buys two things Opal has no equivalent of:
Block a topic rather than an app or a site. Appcognito reads on-screen text locally and blocks the moment your chosen words appear, so pages about the thing you are avoiding get stopped even on sites you never listed. Nothing is stored and nothing is sent.
Opal is built around sessions: start one now, or schedule one. Appcognito has 16 triggers, including location, Wi-Fi network, movement (walking, running, driving), calendar meetings, battery level, charging, monthly dates, an open-count limit, and an AI study guardian that blocks when your screen drifts off your stated topic.
Over a million adult and gambling domains ship inside the app in a local database, plus substances and gore lists. One tap arms them, the contents stay hidden for privacy, and nothing about what you browse is checked against anything remote.
Opal's model is largely motivational. A focus score, streaks, progress you can share, gentle nudges. For a lot of people that is genuinely the right medicine, and it is the honest reason Opal has the fans it does.
Appcognito has streaks too, but the weight sits elsewhere. Strict mode holds a block to its full term and takes 12 or 24 hours to leave. The Unblock Gate puts a mini-game or a breathing exercise between you and the off switch. Uninstall protection means deleting the app is not the loophole. An accountability lock hands a rotating code to someone else entirely.
The difference matters when the two philosophies disagree, which is at 11pm. A motivational app tells you how you are doing. An enforcing app decides what happens next. If you have already tried the encouraging kind and watched yourself override it, that is the signal to move to the other kind.
The flip side is real: if being scored and nudged is what got you engaged in the first place, a stricter app can feel punitive. Appcognito's position on this is that willpower is a resource, not a plan, but that is a philosophy, not a fact about you.
No export file, no account to migrate. It takes about five minutes.
No account, no onboarding quiz, no email. It opens straight into a working app.
Opal's app categories become Groups. Eleven ship ready-made, so there is nothing to assemble.
Opal's scheduled sessions become Actions, with 12 more triggers available than Opal offers.
Run both for a week first. At roughly $99 a year, this is the switch that pays for itself fastest.
Stay with Opal if you are on an iPhone, you move between an iPhone and an Android phone, or the score and the social accountability layer are the specific things keeping you engaged. Those are real reasons and the price is the price.
Switch to Appcognito if you are on Android, you want blocking that actually enforces rather than encourages, you would rather nothing about your usage left the device, or you cannot justify roughly $99 a year for a utility running on your own phone.
The free plan has no time limit and the Pro trial needs no card, so run them side by side for a week before your Opal renewal.
Also compare: one sec if the pause-before-you-open idea appealed, Forest if you want gamification, and the full Android roundup.
Appcognito. Opal is an iPhone-first app and its Android support is newer and more limited, largely because iOS blocking relies on Apple's Screen Time APIs that have no direct Android equivalent. Appcognito was built for Android from the start, so it blocks at the network level, cuts an app's internet independently, blocks by keyword, and needs no account. It also costs roughly a seventh of Opal's yearly price.
Considerably. Opal's premium plan runs to around $99 a year. Appcognito Pro is $1.99 a month, $14 a year, or $39 once for life, and the free plan has no time limit or ads. Over three years that is roughly $39 against roughly $297.
It shows you your own stats on your own device, and that is where they stay. There is no account, no server and no analytics SDK, so there is no dashboard anyone else can see and no weekly email summarising your behaviour. If the appeal of Opal was the gamified score and the social accountability feed, that is the one thing Appcognito deliberately does not do.
Yes, entirely. Blocklists, the filter and all 16 triggers are evaluated locally, so blocking behaves the same offline, on a plane, or on bad mobile data. Anything that checks in with a server has to decide what to do when it cannot, and usually lets you through.
Yes. A parent, partner or friend can hold a rotating 6 digit code, paired by scanning a QR code once. Changing a locked block needs their code and removing it needs their master password typed in person. No account is created and nothing about you is shared with them or with us.
Not yet, with an iPhone version on the roadmap. If you are on an iPhone, or you switch between an iPhone and an Android device, Opal is the better fit today and this page is not going to argue otherwise.
