Dark mode allows you to change the Reddit app from an all white background to black. This allows for easier reading and helps reduce strain on your eyes. You can manually enable dark mode on the Reddit app. Here's how:
- Tap Snoo, the Reddit alien, in the top left hand corner of the app.
- Tap the little moon icon in the bottom right.
As you can see from the image below, tapping the moon icon changes the Reddit app to a black background with white lettering. Read posts will appear in grey. You can return to the normal white background by following the same steps.
