The best app blocker for Android, honestly compared
Every roundup of these says the same six apps are all great. They are not all the same kind of thing, and two of the most popular do not block anything at all. Here is what each one actually does, what it costs, and which failure mode it fixes.
The short answer
- Blocking that actually holds: Appcognito. Strict mode, accountability locks, uninstall protection, $39 once for life.
- Across a laptop and a phone: Freedom. The only one here that syncs one session everywhere.
- Free starting point: Android's own Digital Wellbeing. Turn it on before paying anyone.
- Motivation, not enforcement: Forest or one sec. Both excellent, neither is a blocker.
Before comparing anything, it is worth being honest about why you are reading this. Almost nobody searches for an app blocker because they lack one. They search because the one they have stopped working, and there are only two ways that happens.
It broke. Android is aggressive about killing background services, and some manufacturers are considerably worse than others. A blocker that quietly stops blocking is worse than no blocker, because you were relying on it and did not know.
Or you turned it off. This is the common one, and it is not a character flaw. It is the hot-cold empathy gap: calm-you sets a rule that craving-you can undo in four taps, and craving-you is a different person with different priorities. We wrote about why this keeps happening at length.
Which of those two you are dealing with decides everything below. If the app broke, you need one that is architecturally more reliable. If you turned it off, you need one that makes turning it off expensive. Most roundups never ask.
The comparison, at a glance
| App | Best for | What it blocks | Price |
|---|---|---|---|
| AppcognitoThis site | Blocking that actually holds | Apps, websites, keywords | $39 once, for life (or free) |
| AppBlock | The familiar all-rounder | Apps, websites | ~$34.99 every year |
| Freedom | One session across every device | Apps, websites | $39.99 every year |
| Opal | Coaching and scores | Apps, some sites | ~$99 every year |
| Forest | Gentle motivation | Nothing | ~$3.99 once |
| one sec | Breaking the reflex | Delays apps | ~$40 every year |
| Digital Wellbeing | Free and already installed | Apps (timers) | Free |
Read that price column again. What Freedom charges for one year, $39.99, is a dollar more than Appcognito costs forever. Opal wants two and a half lifetimes' worth every twelve months.
Competitor pricing and features are from public information as of September 2026 and change over time. Check before you buy. Appcognito also sells monthly at $1.99 and yearly at $14 if you would rather not pay up front, and its free plan has no time limit.
1. Appcognito: the strictest option, and the cheapest to own
Full disclosure, since it matters: this is our app, and you should weigh the rest of this section accordingly. What follows is what it does differently, not a claim that it wins for everyone.
Appcognito blocks with a local firewall plus launch blocking rather than by covering the screen. That means a blocked app either does not open at all, or opens and loads nothing, and a blocked website fails in every browser and in-app browser at once rather than one at a time.
The part that matters for the "I turned it off" failure is that it stacks three independent frictions. 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 30 second breather in front of the off switch. An accountability lock hands a rotating code to a partner or friend, paired by scanning a QR once, with no account created. On top, uninstall protection means deleting the app is not the loophole.
It also has 16 triggers rather than just schedules, including location, Wi-Fi, movement, calendar meetings, open-count limits and an AI study guardian, plus over a million adult and gambling domains built in. There is no account, no server and no analytics SDK, so nothing about your usage leaves the phone.
Against it: Android only, so no help if you lose afternoons on a laptop. It is also newer than Freedom or AppBlock, without their track record. And the strictness cuts both ways: if you want gentle encouragement, this is the wrong app.
2. AppBlock: the familiar one
Probably the most installed blocker on the Play Store, and a reasonable default. Scheduling is approachable, it is on both Android and iPhone, and it has been around long enough to be dependable.
Two things send people looking elsewhere. The free tier is ad-supported, which grates in an app you opened to escape attention engineering. And it is subscription-only at roughly $34.99 a year with no lifetime option, which over three years is more than $100 for software running on your own phone. It also blocks by covering the screen via the Accessibility service, so the app underneath is still running and loading.
3. Freedom: the only one that covers your laptop
If your distraction problem is not confined to your phone, this is the answer and the rest of the list is not. Freedom's account and cloud sync exist so one locked session covers a MacBook, a work PC and a phone simultaneously. Nothing else here does that, including us.
The tradeoffs are the account itself, which means your blocklist lives on a server; behaviour when you have no connection, since anything server-coordinated has to decide what to do when it cannot check in; and price, at $39.99 a year or $199 for lifetime.
4. Opal: the best-designed, and the most expensive
Opal is genuinely well made. Its onboarding is the best in the category at getting someone from vague intent to a working setup, the focus score makes progress legible, and the social accountability layer works for people who need other humans involved.
It is also iPhone-first, where Apple's Screen Time frameworks do the blocking, and its Android edition arrived later doing less. At roughly $99 a year it is around seven times Appcognito's yearly price and more than twice Freedom's, with no lifetime option to escape to.
5. Forest: lovely, and not a blocker
This is the one people are most surprised by. Forest does not block any apps. It grows a tree while you stay in the app and kills it when you leave. Nothing stops you leaving.
That is deliberate, and it works on loss aversion: we try harder to avoid losing something than to gain it. For a lot of people a sapling they have watched grow for 20 minutes is genuinely enough. It is also about $3.99 once, and the Trees for the Future partnership plants real trees.
The limit is the day you decide you do not care. A guilt mechanic has no answer for that, and it weakens with repetition: the first dead tree stings, the tenth does not.
6. one sec: the right idea, aimed one level too low
one sec adds a breath before an app opens, and there is real published research behind it: a few seconds of friction measurably reduces how often people follow through. Against mindless opening it often is all you need.
Its limit is structural. Friction only works on someone who has not decided. Against a deliberate, wide-awake 11pm decision, a breathing animation is a formality you wait out. It also puts the pause in front of each app, which accepts that you are already in the mode of opening apps to see what is there.
7. Digital Wellbeing: free, installed, and worth ten minutes
Before paying anyone, open Settings and turn on Android's own app timers, Bedtime mode and Focus mode. It costs nothing, it is already there, and for a meaningful number of people it is enough.
Its weakness is the one that sends everyone here: when a timer runs out, you can extend it in two taps with nothing standing in the way. It is a speed bump with a clearly signposted exit, which is fine if you were only ever drifting, and useless if you are actually pulled.
How to actually choose
Skip the feature lists. Answer these in order:
- Which devices? If a laptop is part of the problem, take Freedom and stop here. Nothing else covers desktop.
- Have you ever disabled your own block? If no, a free tier or Digital Wellbeing is plenty. If yes, you need Strict mode, an accountability lock and uninstall protection, and only some of these have them.
- Apps, or websites too? If sites matter, check it blocks at device level rather than per browser, or switching browser is your workaround.
- Motivation or enforcement? Forest and one sec are motivation. Appcognito, AppBlock and Freedom are enforcement. Getting this backwards is why people conclude blockers do not work.
- What will it cost over three years? Roughly: $39 (Appcognito, once, and then never again), $105 (AppBlock), $120 (Freedom), $297 (Opal). Only one of those numbers stops growing the day you pay it.
The setup most people should actually run
These are not mutually exclusive, and the best results usually come from layering one motivation tool with one enforcement tool. A Forest timer inside an Appcognito block covers both the twenty minutes you care and the ten you do not. If you came from Cold Turkey on a desktop, keep it and cover the phone separately, because locking the laptop and leaving the phone face-up beside it just moves the problem twelve inches.
Whatever you pick, the one setting worth turning on first is whichever makes disabling it slow. Everything else is detail.
Compare any of these directly
- Appcognito vs Freedom: cloud accounts and a yearly price several times higher
- Appcognito vs AppBlock: ads in a focus app, and limits behind a subscription
- Appcognito vs Cold Turkey: desktop only, so your phone stays wide open
- Appcognito vs Opal: built for iphone first, at a premium subscription price
- Appcognito vs Forest: a timer that rewards you, but never actually blocks
- Appcognito vs one sec: a pause before the app opens, but no real block behind it
Frequently asked questions
What is the best app blocker for Android?
It depends on what keeps failing for you. For blocking that genuinely holds when you want to override it, Appcognito: it blocks with an on-device firewall, adds Strict mode, accountability locks and reboot-proof uninstall protection, and costs $39 once for life. For one blocker covering a laptop and a phone together, Freedom. For a free starting point, Android's own Digital Wellbeing. For motivation rather than enforcement, Forest or one sec.
Is there a genuinely free app blocker for Android?
Yes, several. Android's built-in Digital Wellbeing is free and already on your phone. Appcognito's free plan has no time limit and no ads: every way of blocking works, including all 16 triggers, all 11 built-in Groups and keyword blocking, with a cap of one Group and one Action running at a time. AppBlock has a free tier but shows ads on it.
Why do app blockers stop working after a while?
Two reasons. The technical one is Android's battery management killing background services, which hits blockers built on the Accessibility service hardest; a blocker that silently stops blocking is worse than none. The human one is that you turn it off. Every blocker has an off switch, and the version of you who is craving will find it. That is why the features that matter are the ones that make the off switch expensive: a mandatory delay before you can disable it, a code held by someone else, and uninstall protection.
Do app blockers need the Accessibility permission?
Most do. It is how they detect which app you just opened, and it is also the permission that can read everything on your screen, including banking apps and messages. Appcognito moved app blocking off Accessibility onto usage access plus an overlay, which is more reliable under battery management and means the screen-reading permission stays off unless you specifically want keyword blocking or the AI study guardian.
Can an app blocker block websites too?
Some can. The important question is how. A browser extension or a per-browser setting only covers that browser, so opening a different one is a trivial workaround. A device-level network filter, like Appcognito's, blocks a domain in Chrome, Firefox, Samsung Internet, Brave and the in-app browsers inside other apps all at once.
Can I stop myself uninstalling the blocker?
With some of them. Appcognito uses Android's Device Admin API so the app cannot be removed while protection is armed, and it survives a restart. Most blockers do not offer this, which makes uninstalling the obvious way around any block they set.
What is the best app blocker for studying?
One with a locked timer you cannot end early, so a session survives the first wave of boredom. Appcognito's Focus mode with Strict mode on does that. For the harder case there is an AI study guardian: you tell it what you are studying, it reads the screen locally to tell work from drift, and blocks the drift. You bring your own free OpenRouter key.
Is it worth paying for an app blocker?
Only if the paid features are the ones that fix your actual failure. If you have never once disabled a block, free tiers are fine. If you disable them regularly, the features worth money are precisely the ones free tiers hold back: strict modes, accountability locks and uninstall protection. Prices range from about $3.99 once (Forest) to roughly $99 a year (Opal), with Appcognito at $39 once for life.
Try the strict one, free
