While most Dark Mode-oriented jailbreak tweaks support iOS’ native app interfaces, the vast majority lack support for the various web pages you might visit while surfing the web.
Two tweaks launched in September, dubbed Deluminator and Nebula, were some of the first to bring a full-featured Dark Mode experience to web pages in particular. But now, a new release called Umbreon by iOS developer Soh Satoh accomplishes this same goal while providing some additional customizations.
In the screenshot examples above, you can see how white backgrounds on most web pages are darkened to reduce the eye-searing effect that’s typically endured while browsing the internet in a dark environment. Umbreon should play nicely with most standard web pages, but there are some instances where a web page won’t be fully compatible.
After you install Umbreon, you’ll find an extensive
preference pane in the Settings app where you can configure the tweak to your
liking:
Here, you can:
Toggle the tweak on or off on demand
Enable Dark Mode for web pages
Combine custom CSS formatting with Dark Mode CSS
Select different apps to disable features in
Configure a CSS injection delay
Toggle gray background instead of black for Dark
Mode
Enable web image brightness adjustments
Use a slider to set a custom image brightness
level
Enter custom Dark Mode CSS styling if you don’t want
to use the default
Toggle website filtering
Choose whether filter is a black list or a white
list
Choose whether filter should exactly match URLs
or guess websites based on name
Inject custom JavaScript
Toggle filtering for JavaScript injection
The developer includes a respring button at the top right of the preference pane that you can use to save your changes. You should use it any time you adjust the settings in this pane.
Compared to Deluminator and Nebula, it seems like Umbreon intends to offer more features to the end user, but its aesthetics aren’t as streamlined. As you can probably discern from our screenshot examples above, some website elements don’t render as expected, such as the Google search bar text field and the filtering tabs just above the Google search results.
Finally, we should mention that Umbreon looks best when paired with a core Dark Mode tweak, such as Eclipse or Nightshade; otherwise, you'd only be theming web pages and not the apps you use on a regular basis.
If you’re interested in trying Umbreon, then you can download it for $1.00 from Cydia’s Packix repository. The tweak is compatible with jailbroken iOS 10 and 11 devices. Any bugs should be reported directly to the developer such that they can be fixed promptly.
