All three want the same thing for you: fewer hours lost to apps you didn’t mean to open. But they’re not equal. They differ on where the off switch lives, what you pay over time, and whether the thing doing the blocking is something you’d actually want on your desk — and on each of those, Norma comes out ahead.
The quick version. Opal is powerful software, but the switch stays on your phone and it’s a subscription. Brick is the closest rival — physical, bought once, with its own stats — yet it stops at the disc: iPhone only, no leaderboard, and it’s plastic. Norma is the one that’s physical and bought once and syncs to your Mac, machined from steel you’re glad to leave in view.
The three approaches
Opal is a screen-time app: it blocks apps and websites on a schedule, with detailed stats — all on your phone, on a subscription. Brick is a small plastic device you stick somewhere; you tap your phone to it to block your chosen apps, and tap again to unblock. Bought once, iPhone only. Norma is a machined stainless-steel disc you scan with your iPhone: the apps you chose go quiet until you scan again. Bought once, it blocks your Mac too, and it adds presets and an optional leaderboard.

Where each one stands
Opal: the off switch sits on the same phone you’re trying to step away from, so in the moment of weakness it’s one tap away. And because it’s a subscription, the focus stops the day you stop paying. Great software — but it never leaves the screen.
Brick: genuinely good, and the closest thing to Norma — physical, bought once, with its own insights. Where it stops: it’s iPhone only, so the focus doesn’t follow you to your Mac; there’s no leaderboard for when you want a nudge; and it’s plastic, the kind of gadget you tuck out of sight. Norma matches everything Brick does and keeps going.
Norma: physical like Brick, bought once like Brick — then it adds Mac sync, an optional leaderboard, and a steel disc built to sit out rather than hide. Its one catch — you need the disc on hand to start a session — is the same friction that makes it work, and a limited set of emergency unblocks covers the rare time you’re caught out.
Key takeaways
- Opal keeps the off switch on your phone and charges monthly; Norma moves it onto steel, bought once.
- Brick is the closest rival — but it’s iPhone only, has no leaderboard, and it’s plastic.
- Norma does everything Brick does, then adds Mac sync, an optional leaderboard, and a steel build.
- If you want the switch off your phone for good, Norma is the one that goes furthest.
So which should you pick?
If you only want software and don’t mind paying monthly with the switch on your phone, Opal is fine. If you want the switch on a physical object — and you should — it’s really Brick or Norma. And there Norma wins the comparison that matters: the same physical, bought-once focus, but it follows you to your Mac, it adds a leaderboard for when you want one, and it’s a steel object you’ll keep on your desk instead of a plastic one you hide. Brick is good. Norma is the one most people will be happier they bought. Here’s the fuller case for a physical blocker over software, and what the disc is actually made of.
The short version
Software keeps the off switch on your phone. Brick moves it onto plastic, iPhone only. Norma moves it onto steel, syncs to your Mac, and is bought once — the same idea, taken furthest.
One scan. Bought once. Built from steel.
A steel disc that blocks the apps you choose — on iPhone and Mac, with no subscription and no switch left on your phone.
