Brick vs Autonomous Key: Same Lock, A Third The Price

Brick and the Autonomous Key solve the same problem the same way: both are a small physical object you tap your phone against to lock distracting apps, and tap again to unlock. If you are comparing Brick vs the Autonomous Key, the mechanism is not where they differ - the differences are price, platform, and whether you can buy one today. Here is the honest breakdown.

Brick vs Autonomous Key at a glance

Brick and the Autonomous Key use the same tap-to-lock model, so the decision comes down to three things: the Key is cheaper and built cross-platform from the start, while Brick is proven and shipping now. The table lays out the rest.

How Brick and the Autonomous Key work

Both work by pairing your phone with a passive NFC object once, then using a tap to switch blocking on and off. You choose which apps to lock in a companion app, tap to start a session, and the locked apps and their notifications go away until you tap the object again. Neither has a battery or needs wifi after setup, because passive NFC draws its power from the phone during the tap.

The core idea behind both is physical separation. The block only holds if the object is out of reach, so you leave the Brick or the Key in another room, a drawer, or with someone else. That is what makes either one harder to defeat than a software timer you can cancel from the phone in your hand. On mechanism alone, the two are close to identical.

Price - $20 vs about $59

The clearest difference is price. The Autonomous Key is planned at $20, and Brick is about $59, both one-time with no subscription on either side. That makes the Key roughly a third of Brick's price for the same tap-to-lock function. Neither charges a recurring fee, which sets both apart from subscription tools like Unpluq or Opal. If price is the deciding factor and you can wait for the Key to ship, the gap is real; if you want a device in hand this week, Brick is the one you can actually buy.

Platform and setup

On iPhone, the Autonomous Key blocks apps through Apple Family Controls, the native iOS framework Apple provides for app restrictions, which tends to be harder to slip past than workarounds. Brick also supports iPhone and has the longer track record there. On Android, both work, but the experience differs: the Key handles Android through native NFC, while Brick runs on Android with an experience that reviewers consistently report trails its iPhone version. If you are on Android and want the closest-to-equal experience, that difference is worth weighing. Setup on both is a one-time pairing followed by choosing your app groups.

Strictness and bypass

Both devices are built to be hard to bypass, and both lean on the same trick: move the object out of reach and there is no quick way back in. Brick adds a deliberately strict rule - a limited number of lifetime emergency unlocks - which some owners value as a commitment device and others find too rigid. The Autonomous Key uses scheduled locks that hold until you scan the Key, so the friction comes from where you put the Key rather than a hard unlock cap. Neither approach is automatically better; it depends on whether you want a fixed limit or control through physical distance.

Which should you buy?

Buy Brick if you want a proven device you can use today. It has two years on the market, strong reviews from outlets like Parade and NBC Select, and it ships now - none of which a new product can claim. If budget is not your deciding factor and you want certainty, Brick is the safer pick right now.

Consider the Autonomous Key if you want the same tap-to-lock model at a third of the price, native iPhone and Android support, and you can wait for the July 2026 ship date. The honest trade is track record for price and platform: you save money and get cross-platform parity, but you are backing a device that has not shipped yet. If that timing does not work for you, the Key is not the right choice today, and one of the shipping Brick alternatives for iPhone and Android may fit better.

Why we built the Key

I will be straight about why this exists. I have maybe four good hours with my family a day, and I kept losing them to my own phone. I tried timers and screen limits and tapped past every one of them. So I built a passive key I could hand to my wife and physically walk away from - no battery to die, no subscription, no off switch in my pocket. We priced it at $20 because the part that matters is a cheap NFC tag in a finished enclosure, not a premium gadget margin. It is not a better-reviewed product than Brick, because it is new. It is a cheaper, cross-platform take on the same honest idea: the only lock that works is one you cannot talk yourself out of.

Frequently asked questions

What is the difference between Brick and the Autonomous Key?

Brick and the Autonomous Key use the same passive-NFC, tap-to-lock model. The differences are price (about $59 versus $20), form (a cube versus a key), platform polish, and availability. Brick ships now with a two-year track record; the Autonomous Key is cheaper and cross-platform but, as of June 2026, not yet shipping.

Which is cheaper, Brick or the Autonomous Key?

The Autonomous Key is cheaper, planned at $20 against Brick's roughly $59, both one-time with no subscription. The Key is about a third of Brick's price for the same tap-to-lock function. Brick, however, is the one you can buy today.

Do Brick and the Autonomous Key work on Android?

Both work on Android. The Autonomous Key handles Android through native NFC, and Brick runs on Android too, though reviewers report its Android version trails the iPhone one. On iPhone, the Key uses Apple Family Controls. Confirm current support before buying either.

Is the Autonomous Key available yet?

Not yet. As of June 2026, the Autonomous Key is on Kickstarter as a coming-soon campaign and ships in July 2026. Brick is available and shipping now, which is the main reason to choose it if you need a device immediately.

Which is harder to bypass, Brick or the Autonomous Key?

Both are hard to bypass because both rely on leaving the object out of reach. Brick adds a fixed, limited number of lifetime emergency unlocks; the Autonomous Key uses scheduled locks held by the physical scan. Which feels stricter depends on whether you prefer a hard unlock cap or control through distance.

Is the Autonomous Key worth it?

The Autonomous Key is worth considering if you want Brick's tap-to-lock model at a third of the price with native iPhone and Android support, and you can wait for the July 2026 ship. It is not worth it if you need a proven device today, since it has no long-term review record yet. Disclosure: Autonomous makes the Key.

Can the Autonomous Key replace Brick?

For the core job - locking distracting apps behind a physical tap - the Autonomous Key does the same thing as Brick at a lower price. Whether it can replace Brick for you depends on timing and platform: it is not shipping until July 2026, and Brick has the longer track record on iPhone.

Where can I buy Brick or the Autonomous Key?

Brick is available now through getbrick.app. The Autonomous Key is on Kickstarter as of June 2026 as a coming-soon campaign, shipping in July 2026. Prices are about $59 for Brick and a planned $20 for the Key.
