There’s a lot more coming in the near future. Dark Mode will be available in Excel, PowerPoint, Word and a host of other Microsoft mobile apps when iOS 13 and iPadOS arrive (most likely in September), Plans are also underway to bring it to OneDrive and Planner on the web. All told, you might get to stay shrouded in darkness no matter what you’re working on — at least, so long as you live in Microsoft’s ecosystem.
