FSNotes is modern text editor (like nvALT) on steroids. FSNotes respect open formats: plain/text, markdown, rtf, and stores data in file system. You can view, edit, copy data in favourite external editor and see live result in FSNotes. Markdown eidtor highlight code blocks on 170 languages, inline images available too. Swift 4, open source.
Great combination of minimalistic UX of Apple Notes and working with Markdown files of Obsidian. Not as feature-rich as Obsidian, but easier to use and more responsive.
Very convenient to sync files between devices via iCloud.
