I would second the Obsidian recommendation for anyone that is comfortable writing in Markdown—but as you’ll read in the links above, as a tool for working with Scrivener, rather than replacing it (it doesn’t strike me as viable given how it is very much a note-taking tool rather than a long form writing tool, but then I’ve seen people say they prefer Bear to Scrivener, so they must be using Scrivener in a very different way than I do, which is fair).
The main point of conflict between Scrivener and it is Obsidian’s non-standard link markup, which doesn’t like how Scrivener uses square brackets in the sync file names, but if you’re using it as a simple “front end” to your project’s writings on mobile, rather than a system of its own, that isn’t a relevant conflict. Otherwise, the two work very well together indeed.
