When you check out photos and videos on Instagram, the bright white standard layout can literally be a thorn in the side, especially in dimly lit environments where the bleached user interface feels dazzling. Fortunately, in the iPhone and Android app, there is a very easy way to switch from normal Hell mode to Dark Mode look.
For the longest time, the only way to get Dark Mode on Instagram was to use an unofficial IG client or jailbreak. You can still choose this route, but there was also a built-in Smart Invert option in iOS 11 and later, which acted as a pseudo-dark mode. You can continue to use this because it's almost exactly like the real dark mode. In previous versions of iOS, Classic Invert also changed the colors in the media ̵

Instagram tacitly adds support for iOS 13's new Dark Mode feature. So if you want to replace whites with blacks in Instagram while leaving the photos untouched, you just need to do a simple flip switch.
First, of course, you need to upgrade your iPhone to iOS 13 if you have not already. Then make sure you update the Instagram app to version 114.0 or later. Next, swipe the Control Center and hold down the Brightness slider. At the bottom of the full-screen brightness control, you will see a new "Dark Mode" switch. Tap to turn it on, and you're done.
To turn dark mode on and off even faster, add the Dark Mode control to the Control Center via Settings -> Control -> Customize Controls. This allows you to switch the dark mode in just two steps instead of three steps. The Dark Mode in iOS 13 even has a scheduling system so you can turn it on and off at set times.
Option 2: Use Smart Invert in iOS 11 and iOS 12
If you have not upgraded to iOS 13 yet, the next simpler option is Smart Invert, which was included on iPhones since iOS 11. The option is available in the Accessibility settings under "Show Accommodations." Section. Tap "Invert Colors" and then turn on "Smart Invert". This is a pretty impractical way to disable and enable Smart Invert whenever you need it. However, there's a way to create a shortcut for your Home or Side button that lets you instantly turn it on or off. You can also add the accessibility control to the Control Center and use it.
Option 3: Use Jailbreak Optimization in iOS 11 and iOS 12  If you do not mind jamming your iPhone, there are stable jailbreakers for iOS 11 and iOS 12. After the jailbreak IGDarkMode by the developer Chloe Kuznetsov is quite easy to install and activate. Best of all, you do not need to install an external repo in Cydia or Sileo to get the tweak. Follow the steps below to get it up and running.
Step 1: Install IGDarkMode
Get your iPhone, open Cydia, and tap the magnifying glass icon at the bottom right to access the search function. From there, type "igdarkmode" in the search bar, and then tap optimization as it appears in the results panel.
] On the page, tap Details for IGDarkMode in the top right corner of "Modify". Click "Install" when the confirmation prompt appears at the bottom of the screen.
Tap on Confirm in the upper right corner. The tweak will now download to your device. Wait for the process to complete. Then click on "Restart SpringBoard" to restart the iPhone and complete the installation of IGDarkMode.
After re-applying the spring force, you still need to enable optimization to apply the dark design to your Instagram app. Therefore, open the Settings app on your iPhone Tap IGDarkMode. Just inside, tap the switch next to "Enabled" to enable optimization, and then return to the Home screen.
With IGDarkMode enabled, you can now enjoy Instagram as usual. This time, however, the app has a dark theme, which is visually much more appealing, but also eye-friendly thanks to the significant reduction of white and blue light.
