Screen time apps fail when the person who set the limit is the same person who can undo it. Brick solves that problem with a physical object. It's a small NFC device about the size of a saltine cracker, and tapping your phone to it instantly locks your most distracting apps. You can't reverse it in the app settings, can't enter a PIN to unlock it, and can't override it from your couch.
It's one of the most effective picks in WhistleOut's best screen time apps roundup because the accountability is physical, not digital.

If you're setting limits for multiple people in your household, it's worth making sure your family plan is actually competitive. Many carriers charge significantly more than MVNOs offering the same coverage on every line.

What is Brick?
Brick is a physical NFC device that pairs with a free app on your phone to lock a customizable list of distracting apps the moment your phone makes contact with it. You set up a permitted list in advance (like maps, your banking app, camera, contacts), and everything outside that list locks on tap. To restore full access, you tap the Brick a second time. Without the physical device nearby, your permitted list is all you get.

Keeping your apps up to date ensures you're always getting the latest features, bug fixes, and security improvements. Learn how to update the apps on your iPhone and your Android. It takes less time than you think.
Why physical accountability works when apps don't
Every app-based screen time tool eventually runs into the same problem: the unlock is always one tap away on the same device you're trying to put down. Brick removes that option. The only way to restore access is tapping the physical device, which means if you don't have it with you, the lockout holds.

There is one safety valve: the Emergency Unbrick feature. Inside the app, you get five lifetime emergency unlock passes per device. Use them all and you have to contact Brick's customer support for more. It's designed to be used genuinely, not as a regular workaround.
Brick also supports connecting one phone to multiple devices, which is useful for creating different blocking environments in different locations. You can have one Brick at your desk for work hours and another at a family member's house for shared sessions.
Why Brick works so well for families with kids and teens
My aunt uses Brick with her 15-year-old and her 10-year-old during study hours. The kids can't access social media or games without physically reaching the device she holds onto. There's no parental control menu to find, no PIN to guess, and no account settings to navigate around. The lockout holds as long as the parent has the Brick.
If your kids are old enough for a smartphone but young enough to need hard limits, Brick is the most tamper-proof option available without buying a dedicated dumbphone. It keeps the phone functional for calls, messages, and maps while blocking everything else on the list.
Same Verizon coverage, lower monthly bill
Verizon MVNOs use the same towers for a fraction of the cost. If you're paying full Verizon prices across multiple lines, comparing MVNO options could save you a significant amount every month.

Brick: FAQ
How does the Brick device work?
Brick is a small NFC device that pairs with the free Brick app. Tapping your phone against it instantly locks your designated distraction apps, and tapping it again restores full access.
Can you unlock Brick without the physical device?
Each device comes with five lifetime Emergency Unbrick passes accessible inside the app. Once all five are used, you have to contact Brick's customer support for more.
Does Brick work for parental controls?
Brick is best suited for parents wanting a hard lockout on a child's device, since the physical device is required to unlock apps and there's no account menu the child can access to bypass restrictions.
Does the Brick app cost money?
The app is free, but the physical Brick device costs $65. One device can pair with multiple phones, and one phone can connect to multiple Brick devices.
