How to Force “Dark Mode” in Any iPhone App with Smart Invert

If you love Dark Mode but your favorite iPhone or iPad app—or website—doesn’t support Dark Mode, you can force a simulated “Dark Mode” everywhere using Apple’s built-in Smart Invert accessibility feature. Here’s how to set it up.

What Is Smart Invert?

Smart Invert is an Apple accessibility feature that inverts the colors on your screen (like a negative image), but with a twist. It’s “smart” because it usually prevents images, videos, and some apps that are already dark-colored from getting inverted. It was designed for people with vision loss or other vision issues that might benefit from an inverted screen but might not want to see inverted images.

Why Not Use Dark Mode?

Apple’s system-wide Dark Mode (first introduced in iOS 13) generally works well and is supported by an increasingly large number of iPhone and iPad apps, but some apps with largely white interfaces still don’t support it. Also, if you want to browse the web at night without waking a partner or spouse—and you’re reading a largely light-colored site without a dark mode—Smart Invert does just the trick to keep the light low.
