Free app blockers for Android: what actually works

Almost every app blocker on Android is free to install. The interesting question is what each one holds back, because the feature people actually need — a mode that is genuinely hard to undo when you want to undo it — is very often the one behind the paywall. Here is what the main options give you without paying, and the single test that separates the ones that work from the ones that just make you feel organised.

What "free" means in this category

Three different things, and the difference matters:

• Free and built in. Digital Wellbeing ships with Android. Nothing to install, nothing to buy, no account.
• Free to install, paid to be strict. The common model. You can set up blocks for nothing, but the strict or locked mode that stops you from simply switching it off is a paid upgrade.
• Free, with the core mechanic included. Rarer. The thing the app is actually for is in the free tier.

Before you commit to any of these, check which of the three you are dealing with. A blocker whose only real defence is paywalled is a usage dashboard with extra steps.

The main options

Digital Wellbeing (built into Android)

Google's own tool. App timers, Focus mode, Bedtime mode, and a genuinely useful breakdown of where your hours went. It costs nothing and it is already installed.

The catch: when a timer runs out you get a dismissible screen, and extending it takes a couple of taps. It is excellent at telling you the truth about your usage and weak at stopping you in the moment. For a mild habit that is often enough. For a compulsive one it rarely is.

AppBlock

The biggest dedicated blocker on Android by some distance — over 10 million downloads and a 4.6 rating from more than 241,000 reviews at the time of writing. Blocks apps and websites, supports schedules and profiles, and offers a strict mode designed to be hard to escape.

The catch: it is free to install with in-app purchases, and the strictness features are the ones most likely to sit in the paid tier. If strict mode is the reason you are installing it, confirm what the free version includes before you rely on it.

Stay Focused

Granular limits — per app, per day, per launch count, per time window. Rated 4.6 on the Play Store. If you like the idea of "Instagram, twenty minutes, maximum six opens", this is the one built for that.

The catch: granularity is work. The people who get the most out of it are the ones who enjoy configuring it, which is a smaller group than the people who need it.

ScreenZen

Takes the friction approach rather than the wall approach: it interrupts the reflex with a pause and a prompt before the app opens, making you choose deliberately instead of blocking you outright. Rated 4.6.

The catch: friction works well against absent-minded opening and much less well against a deliberate decision to scroll. If you are opening the app on purpose, a pause screen is a speed bump.

one sec

The purest version of the friction idea — a forced breathing pause before an app opens. Well rated at 4.6 and genuinely effective at breaking the unconscious reach for a phone.

The catch: same as ScreenZen. It is designed to interrupt a reflex, not to enforce a boundary.

Forest

The gamified timer — plant a tree, leave the app, the tree grows. Rated 4.5, and the best known app in the category. It works through investment rather than restriction: you do not want to kill the tree.

The catch: it relies on you caring about the tree at the exact moment you stop caring about the tree. We wrote about that trade-off in more detail in the Forest alternative guide.

FocusComet

Ours, so weigh this accordingly. It is free on Android, and it does something structurally different: instead of showing you a block screen when you open a distracting app, it removes the apps from your phone for the length of a session you choose, then puts them back when the session ends.

The catch: it is Android only, and if what you want is detailed usage analytics rather than absence, Digital Wellbeing does that better and it is already installed.

The test that actually separates them

Forget feature lists. There is one question worth asking about any blocker, free or paid:

At the exact moment you want to break it, how much effort does breaking it take?

That moment is the whole game. Everything else — schedules, statistics, streaks, profiles — is preparation for a decision you make in about a second and a half, usually while bored and slightly tired. Rank the options by that and the picture simplifies:

The reason the free tiers of most blockers disappoint is now visible: they sit in row three. They are perfectly good at reminding you of a decision you already made and poor at holding you to it.

So which should you pick?

• You want to understand your usage before changing it — Digital Wellbeing. It is free, built in, and honest.
• You open apps without meaning to — one sec or ScreenZen. Friction is the right tool for a reflex.
• You want detailed rules and you enjoy configuring things — Stay Focused or AppBlock.
• You want a real barrier and you are willing to pay — the strict mode of a paid blocker is the honest recommendation here.
• You want the app to simply not be there, without paying — that is the gap FocusComet was built for.

It is also completely reasonable to run two: Digital Wellbeing for the data, something stricter for the hours that matter.
