I'm working on a Zettelkasten notes app that focuses on getting the UX details right. It takes aspects of Notational Velocity, outliner apps, Zettelkasten, and wikis and combines them into an opinionated Mac app.

What makes the app a little different from others is that it's kind of halfway between an outliner and a wiki. You can place notes in a tree hierarchy, but they can be free-floating as well. You can link to other notes using wiki-style text links, and each note has a unique address, so you don't need to give notes a title or a filename.

Notes can even appear as a child note of more than one parent. The idea is that you can jot down an idea quickly without a lot of friction and then later either add sub-notes to create a note "tree" from it or add it to an existing tree. The tree gives structure to related notes, but the wiki-style links allow you to connect notes together outside of that structure. (I consider the tree structure a "hard" relationship and the links a "soft" one.)

There isn't a single uber-tree where every note goes. Your notebook ends up with lots of free-floating notes and lots of small trees of organized notes, like a card-based Zettelkasten system. You can use search and various filters to find and stumble upon notes easily.

Notes can either be stored in iCloud (so that they sync across devices) or saved in a folder as simple Markdown files.

If you're curious, you can help beta test it. More info here: https://zettelkasten.ussherpress.com/
