Hidden Value vs Opal
The short version: most focus tools — Opal included — work by blocking. But a block is just a wall between you and the dopamine; the moment it comes down the craving is still there, often stronger for the wait. Hidden Value takes the opposite approach — it makes the distraction feel not worth it in the first place by showing you the real dollar cost of every scroll, so the behaviour actually changes. On your work computer, that's what sticks. Opal is the better pick if your problem is your iPhone — here's the honest breakdown.
Most "X vs Y" pages are thinly disguised sales pitches where the author's product wins every round. This isn't that. Opal is a genuinely good app, and for a lot of people it's the right pick. The honest answer to "which should I use" depends almost entirely on where you get distracted — your phone or your work computer — and what you want the tool to do — block the thing, or make you feel its true cost.
The quick verdict
Choose Hidden Value if…
You lose focus in Chrome on your work computer and you bill by the hour. You want a real hard-stop when you need one — block a site outright, or set a limit and let the tab close itself — plus the distraction shown as a dollar cost, so you stop wanting it. Built for founders, freelancers, and solopreneurs whose time converts directly into money.
Choose Opal if…
Your problem is your iPhone (or iPad) specifically, you want OS-level app-blocking and deep Apple Screen Time integration on mobile, and you like scheduled focus sessions on a polished, mobile-native app.

| Apple Screen Time | N/A — works in Chrome, not via Screen Time | Yes — deep integration |
| Shows cost in dollars | Yes — your Hidden Cost at your hourly rate | No |
| Style of control | Graduated — friction, popups, an automatic tab close at your limit, or a permanent Always Block | Scheduled focus sessions with app/site blocking |

What is Hidden Value?
Hidden Value is a Chrome extension that tracks the sites eating your time and reframes them as opportunity cost: a running dollar figure based on your hourly rate. When you reach for a distracting site, it adds friction and shows you the cost before you commit. If that's not enough, it escalates — a popup, then an intervention, and if you still don't stop, it closes the tab for you automatically.
The goal isn't just to stand between you and the dopamine — it's to make the source less addictive, so you stop wanting it as much in the first place. When every scroll carries a visible price, the pull weakens on its own, and you can see exactly what the habit is costing you in hours and dollars. That's the part that lasts, especially on the work computer where your billable hours actually live.
What is Opal?
Opal is a focus and screen-time app built primarily for iPhone, with a companion Mac app. It leans on Apple's Screen Time framework to block distracting apps and websites during focus sessions you schedule or start on demand, and it wraps the whole thing in a clean, gamified, mobile-native experience. If your biggest time sink is picking up your phone and falling into Instagram or TikTok, Opal is squarely aimed at you.
Where Opal genuinely wins: it's the stronger tool on mobile today. Hidden Value is built for desktop Chrome (an iPhone app is coming soon), so on the phone Opal's OS-level Screen Time enforcement does something a browser tool can't yet. Its focus-session model and polish are excellent. If iOS is where your attention leaks right now, we'll happily point you to Opal.
A block is a wall between you and the dopamine — but the dopamine is still waiting when the wall comes down, often bigger for the anticipation you built up. Hidden Value isn't just a wall. It works on the source: when the true cost is visible every single time, the scroll itself starts to feel not worth it — and if that's not enough, an automatic tab close steps in as the backstop. One delays the reward; the other dissolves the pull. That's why, on a desktop, changing what you want beats blocking it.
Where Hidden Value is the better choice
- You want the tab to close itself, not to lean on willpower. Set a daily limit and Auto Close ends the session for you the moment you hit it — and Always Block puts a site fully off limits when you're done with it entirely. It's not "just a number": the enforcement is real, and once you can see the cost you stop wanting to switch either one off.
- You want the pull itself to weaken, not just a wall to sit behind. Hidden Value's angle is making cheap dopamine stop feeling worth chasing in the first place — when every scroll shows its real cost, the craving loses its grip on its own.
- You bill by the hour and want to see the actual time wasted. A real dollar figure — your Hidden Cost — hits differently than a generic "you've been on this app for 20 minutes" nudge. Curious what your number is? Run it through the screen time cost calculator.
- Blockers never stick for you. If you've disabled every wall you've ever installed, a tool that makes the scroll feel not worth it beats another thing to switch off. More on that in our guide to stopping doomscrolling during work hours.
Where Opal is the better choice
- Your distraction is on your phone. Hidden Value is built for desktop Chrome today (an iPhone app is coming soon), so for now your phone is Opal's turf. If you doom-scroll in bed, not at your desk, Opal is the right tool.
- You like scheduled focus sessions on mobile. Opal's session model and gamification are a genuine strength.
Can you use both?
Yes — and honestly, that's the ideal setup for a lot of people. Put Opal on your phone and Hidden Value in your work browser. They cover different battlegrounds and don't step on each other: one handles mobile app-blocking, the other handles desktop cost-visibility. You don't have to pick a side; you have two different leaks to plug. (If your problem is a locked, cross-device session instead of iPhone-specific blocking, see our Hidden Value vs Freedom comparison.)
Frequently asked questions
Is Hidden Value or Opal better?
For distraction on your work computer, Hidden Value — it changes the behaviour instead of just blocking it, by making the real cost of every scroll visible so the feed stops feeling worth it. Opal is the better choice today if your problem is your iPhone, where its app-blocking and Apple Screen Time integration shine (a Hidden Value iPhone app is coming soon). Different devices, different jobs.
Does Opal work on Chrome or desktop?
Opal is built primarily for iOS, with a Mac companion app. It isn't a Chrome extension, so it doesn't live inside your desktop browser the way Hidden Value does. If your distraction happens in Chrome during work, a browser-native tool fits that moment better.
What is a good Opal alternative for desktop?
Hidden Value is a strong Opal alternative if your problem is browser-based. Instead of blocking apps on your phone, it tracks the sites eating your time in Chrome and shows their opportunity cost in dollars at your hourly rate, then adds friction the moment you reach for them.
Can I use both Hidden Value and Opal?
Yes — for many people that's the best setup: Opal guarding your phone, Hidden Value guarding your work browser. They don't overlap or conflict. One covers mobile app-blocking, the other covers desktop cost-visibility.
