Brick Review: A Physical Object That Locks Your Phone

What it actually does

Brick is a small physical tag. You tap your phone against it to start a session, and the apps you have chosen become unavailable. To unlock them you must physically return to the Brick and tap again.

The point is where the barrier lives. Every software blocker keeps the escape hatch on the same device as the temptation, a few taps away in a settings menu. Brick moves it into physical space. If you leave the Brick at home, unlocking Instagram means going home.

That converts a moment of weak willpower into a logistics problem, and logistics problems are much easier to lose to. It is the same principle as the highest-return change in the site's 30-day tracking experiment — moving the phone charger to the kitchen — sold as a product.

How hard it is to escape

Firm, and unusually honest about it. Brick states that it "creates physical separation, requiring a rescan to exit."

It is not unbeatable — it is software on your phone plus a tag — but the failure mode it defends against is the realistic one: not a determined attacker, but you, bored, at 11pm, with the unlock two taps away.

What it costs

Brick lists the device at $59.00, currently discounted from a higher regular price, as a one-time hardware purchase. The app is free for life on both iOS and Android with no subscription — stated explicitly as "no subscriptions, ever."

It requires Android 12.0 or later, or iOS 17.0 or later. One Brick works with multiple phones, and you can use several Bricks in different places.

Where it falls down

The obvious failure mode is carrying it with you, which defeats the entire mechanism and is entirely possible to do without noticing. Brick works if you are disciplined about where you leave it, which is a smaller ask than being disciplined about your phone, but it is not zero.

It is also the most expensive option here for what is, functionally, a blocker with a physical key. At $59 against free tools like ScreenZen, the premium buys the physical separation and nothing else. Whether that is worth it depends entirely on whether you have already tried software and routed around it.

Who it suits

Someone with a documented history of disabling their own blockers. If you have installed three apps and defeated all three, the problem is not the app — it is that the exit is always in your pocket. That is the case Brick is built for, and the only one where the price makes sense.
