Dunar vs Opal
Opal is the best-looking focus app on iPhone. But it leans on Apple Screen Time - which has its own escape hatches - it's iOS-first, and it's a recurring subscription. Dunar gives you truly unbypassable blocking on every platform, for one payment.
Every device · One blocklist · Built to be unbypassable
The honest version
Opal is a beautifully designed focus app with great insights and motivating streaks, and on iPhone it's a pleasure to use. Its limits are structural: it's iOS-first, it's built on Apple's Screen Time (which can be undone by resetting the Screen Time passcode or deleting the app), and it's a subscription that adds up year after year. Dunar is for people who want the same focus on Windows, macOS, Android and Linux too - with blocking that doesn't depend on Screen Time and can't be switched off, for a single purchase.

Opal has expanded beyond iOS over time, but it remains iPhone-first and built on Apple's Screen Time framework.
It's gorgeous and motivating - focus sessions, streaks, a focus score and clean insights into where your time goes. Few apps make focus feel this good.
On iPhone the experience is polished and fast, and the gentle gamification genuinely helps a lot of people build a habit.
If you live entirely on iOS and want encouragement more than a locked door, Opal is a lovely choice.
Every device, not just iPhone
Opal is iOS-first. Dunar treats Windows, macOS, Android and Linux as first-class, so a block follows you to whichever screen you'd otherwise escape to.
Not built on Screen Time
Opal leans on Apple Screen Time, which you can undo by resetting the passcode or deleting the app. Dunar doesn't depend on it, so that whole class of bypass is off the table.
Buy it once
Opal is a recurring subscription. Dunar is a one-time purchase - no annual renewal to cancel the moment you want back in.
Common questions
Dunar is built to be exactly that. Where Opal is iPhone-first, Dunar covers iOS, Android, Windows, macOS and Linux with the same strict blocking on every one.
Opal is built on Apple Screen Time, so the usual Screen Time escape hatches apply - resetting the Screen Time passcode or deleting the app can undo a block. Dunar doesn't rely on Screen Time and is designed so those routes don't work.
No. Opal Pro is a recurring subscription; Dunar is a one-time purchase that covers all of your devices, gone for good.
Dunar's focus is on being genuinely unbypassable across every device. If what you want most is a blocker that holds even when you're desperate to get back in - on any platform - that's the gap Dunar fills.
