Noxri Frequently Asked Questions

Download Noxri from the App Store, open Safari, tap the 'Aa' icon in the address bar, choose 'Manage Extensions', toggle Noxri ON, and tap 'Review' to grant permission. The dark theme applies instantly to every website you open.

iOS Safari has no built-in setting to force dark websites, so you need a Safari Web Extension like Noxri. Install it from the App Store, enable it once in Safari's 'Aa' menu, and every site — including Amazon, Reddit, YouTube and Google — will use a comfortable dark background.

iOS system Dark Mode only changes the Safari interface — menus, toolbars and the keyboard. It cannot recolor a website's content unless the site's developer shipped its own dark CSS. Noxri closes that gap by dynamically rewriting backgrounds and text on every page.

No. Unlike desktop Chrome, iOS Safari ships with no global 'force dark on every website' flag. Apple only darkens its own UI and leaves web content untouched. To get a true dark theme for every page, you must install a Safari Web Extension such as Noxri.

Sometimes iOS needs a moment to register a newly installed extension. Force-close Safari (swipe up from the bottom of the screen), reopen it, and tap the 'Aa' icon again. If it still doesn't appear, restart your iPhone once — that resolves the issue in virtually every case.

The flash happens because the website paints its light-colored background before any dark-mode styles can run. Noxri inserts an instant dark canvas the moment a page starts loading, so you see a solid dark background rather than a blinding white flash.

First make sure Noxri is toggled ON for that site from the 'Aa' menu. Some sites render heavily via JavaScript — tap Noxri's 'Deep Scan' option on that page. Clearing Safari's cache (Settings → Safari → Clear History) fixes any remaining stuck styles.

No. Basic color-invert tools make faces look blue and logos look wrong. Noxri's Smart Invert engine only retargets backgrounds and text — images, videos, avatars and brand logos keep their original colors, so Instagram photos, YouTube thumbnails and product shots look exactly as intended.

Yes, significantly on OLED iPhones. OLED pixels displaying pure black are switched off entirely, so replacing a bright white webpage with a true black background cuts screen power draw by up to 60% at high brightness — one of the biggest single-setting battery wins on iOS.

Generic extensions ported from desktop can stutter on mobile Safari. Noxri is written natively for Apple Silicon and runs its color engine inside Safari's rendering pipeline — so pages paint in a single pass with no scrolling lag, no janky reloads and no measurable slowdown.

Dark mode reduces pupil dilation and perceived glare in dim rooms, which most users find noticeably more comfortable for late-night reading. It is especially helpful for migraine-prone users and anyone with photosensitivity, though bright ambient light is still best for daytime reading.

iOS shows that warning for every extension that modifies web pages — it's Apple's generic permission notice, not a specific claim about Noxri. To repaint a background, Noxri must be allowed to see page HTML, but all processing happens on-device and nothing is ever uploaded.

No. Noxri is built privacy-first. Every color transformation runs locally on your iPhone. We do not collect, log, transmit or sell your browsing history, passwords, form data, cookies or any identifier. There are no analytics SDKs inside the extension.

No. Noxri runs entirely on-device. Once installed and enabled, it works offline, on airplane mode, and on cellular — any time Safari is open. Because it never calls a server, there is no extra latency added to page loads.

Yes. Noxri is a universal app — one download installs on iPhone, iPad and iPod touch. It works identically on iPadOS Safari, including Split View and Stage Manager, and scales cleanly on 11-inch and 13-inch iPad Pro displays.

Noxri supports iOS 17 and later, including iOS 18 and iOS 19. Earlier versions of iOS do not support the modern Safari Web Extension framework at all, so a recent iOS release is required — the same baseline Apple enforces for every third-party Safari extension.

No. Smart Invert is an accessibility feature that flips colors system-wide, often turning photos into blue-tinted negatives and breaking brand logos. A real dark mode extension like Noxri only replaces backgrounds and text, leaving images and videos in their original colors.

Unlike Dark Reader — a desktop-first project with no official iOS app — Noxri is built natively for iPhone, so there is no battery drain and no scroll lag. Unlike Noir (paid upfront), Noxri offers a free core version so you can try it before buying advanced customization.

Noxri is the top-rated native Safari dark mode extension for iPhone and iPad. It combines a free tier, OLED-true black, image-safe Smart Invert, per-site whitelist, auto-schedule and zero data collection — feature parity with paid competitors at no upfront cost.

Yes. Tap the Noxri icon in the Safari 'Aa' menu while on the site and choose 'Off for this site'. The whitelist is remembered forever, so sites with a great native dark mode (like Twitter or Notion) stay in their original look.

Yes. In Noxri's settings choose 'Follow System' — the extension then switches on when iOS toggles to dark appearance (typically at sunset) and off at sunrise. You can also pin it to 'Always On' or 'Always Off' if you prefer full manual control.

Yes. Noxri ships a custom time schedule — set 'On from 20:00 to 07:00', for example, and dark mode activates only during that window. Combine it with 'Follow System' if you want sunset-to-sunrise scheduling without entering times manually.
