Noir is a Safari extension that automatically adds a dark mode to every website you visit. It makes browsing the web at night so much better. With Noir, you won’t be blinded by bright websites ever again. And the results look great too. Noir generates a custom dark style for each website you visit, based on the colors that are used on a page. You won’t even notice this happening in the background – that’s how fast it is – but you’ll certainly appreciate the end result: a beautiful dark mode tailored for each website, where contrast is preserved and highlights still pop. And with over 20 built-in themes and the ability to create your own, you can customize the results exactly the way you want. Noir works with any website you visit in Safari, automatically. By default, Noir is linked to your device’s Dark Mode, so websites will only go dark when you want them to. But you can easily customize this to your liking, even per website. Only want to use Noir on just a few specific websites? Sure thing! Disable Noir on some websites? No problem! Built from the ground up for iOS and iPadOS, the app feels right at home on your device. It supports the brand new Safari web extension feature, which means there’s no need to manually activate it every time you load a new page. The app also tightly integrates with system features such as Shortcuts, Control Center, Focus Filters, and Widgets to fully integrate Noir in all your workflows. And your settings are automatically synced to all your devices using iCloud. And just as importantly, Noir takes your privacy seriously: it doesn’t collect any of your browsing data. Period. Noir is made by an indie iOS developer. It does not include any subscriptions or ads. Buy Noir once, use it forever. Notes: • Found a website where Noir’s dark mode doesn’t look just right? Let me know by reporting it. The app will be frequently updated to address issues that are reported. Privacy Policy: • The Noir extension requires access to the websites you visit to analyze the existing style of the page and to override it with Noir's dark style. • Noir never collects your browsing data. The only data Noir ‘collects’ are your settings, and those will never leave your device or iCloud account. • You can read Noir’s full Privacy Policy at https://getnoir.app/privacypolicy

Verdict
The clearest difference is rating: Noir at 4.6 against Sci's 4.0. Noir also leads on review sentiment (81% vs 56%) and update cadence (every 3 weeks vs every 3 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
