When apps switch out the white background with a black one, it looks like the content is basically floating on the screen. The edges of the phone just disappear. But there’s a practical benefit to using this dark mode as well. As the background pixels aren’t illuminated, you end up saving on a lot of battery life. But if you think it’s a bit too basic, try using Bear. No matter what you want to do with the text, start with the Drafts app. Now that Drafts has a really cool true black theme, you can make Drafts the place you compose all your thoughts.
