You can put sheets into groups and create filters that group together sheets that share a common keyword or phrase. Ulysses automatically saves everything you write in one convenient library, and lets you organize pieces of text (sheets) however you see fit. Plus, when you format with MarkdownXL, you can seamlessly export your work to a number of formats, and even publish directly to Wordpress and Medium. So when you use the app via Setapp, you can have the same license for iOS.
Ulysses also has an iOS client for editing your texts on iPhone and iPad. Every formatting change can be made with characters, so there's no need to hunt for the indent button or line spacing menu anymore. When you're ready to format, Ulysses employs a simple, web-ready formatting system called MarkdownXL that allows you to format your text without ever using your mouse. Instead of cluttering up the page with formatting options, the app provides a simple, clean word processor where all you see is the words you've written on a blank page. Ulysses is a word processor that rethinks the way we write.
