A dedicated outliner for macOS, iPadOS, and iOS.

Zavala 3.x has been released! You can download it in the App Store.

Let's talk outliners! Head over to Discussions for outliner discussion and to express what you would like to see in an outliner application. Be sure to read our Code of Conduct.

We are looking for active user contributors. We need people to test the application and provide feedback, including your ideas about what you would like to see in an outliner. If you find a bug and it isn't already in Issues, you can add it there. If you have an idea you would like see implemented, bring it up in Discussions.

This is your chance to help shape what Zavala will become but, we aren't looking to build an outliner by committee. Not all features can be implemented due to time constraints. Some features can't be implemented because they conflict with other ones. We also have specific Design Goals. All input is welcome, but the primary project contributors have final say in the design.

We welcome contributions!

If you’d like to contribute:

1. File a ticket describing the bug you want to fix or feature you want to add. Or find an existing ticket.
2. In Discussions under the Work category mention that you would like to work on the item. We will probably discuss implementation details. This is very important, because there might be things you need to know before you start work.
3. Once approved, then go for it. Write the code, then do a pull request. We’ll either have comments or we’ll merge it. (We might revise it afterward, of course.)

I would like to thank John Gruber and Brent Simmons for inspiring this project. Their dedication to outliners and disatisfaction with the current generation of them is ultimately what got this project going. In fact John tweeted this:

I would kill for a good simple outliner that synced across iOS and Mac, and had a great simple UI on all three platforms.

If there was a mission statement for Zavala, that would be it.
