zk is described as 'Plain text note-taking assistant meant for use alongside a separate text editor program' and is an app in the education & reference category. There are more than 25 alternatives to zk for a variety of platforms, including Mac, Linux, Windows, Android and Self-Hosted apps. The best zk alternative is Obsidian, which is free. Other great apps like zk are Logseq, Notesnook, Zettlr and Zim.

This is what I personally use in place of zk on mobile. It's missing its own in-built ability to generate random note IDs (if that's what kind of ID you use) but it otherwise does things like let you link between notes by ID instead of just filename.
