Zim vs Checkvist

Notes can contain links to other notes, allowing you to reference important information when needed. This way the user can connect and reference many different pages in the app, keeping things clean and structured, unlike Evernote, which makes this a good Evernote alternative.

If/when the app is no longer developed (or if the user simply decides to no longer use the application or view/edit it on a non-supported platform), this can still be done with any plain-text editor.

Zim will automatically create a folder structure that fits your page hierarchy and adds/removes files such as images to/from appropriate folders.

Zim supports HTML, LaTeX, Pandoc Markdown, and RST. This allows ones documents to be easily used in a wide selection of other apps.

Windows, Linux, and BSD are supported with their own clients. This is nice for those that use multiple operating systems but still want to use the same app on each.

Checkvist hits a sweet spot between minimal and complexity. It gives you a host of options and extras to use on your lists, but you can completely ignore them if you don't need them and keep it very simple. This makes Checkvist a one-stop shop, regardless of what type of 'list' you need.

Search filters help you search for tasks by tag, due date, assignee, etc.

To-do lists often need to be grouped and regrouped for clarity. The outline-based nature of Checkvist makes it easy to move things across categories, to increase and decrease priority, etc.

Parses markdown, html links, hashtags to become formatted text, clickable links, and tags, respectively.

Checkvist offers many free features if you are using this individually.

Any item can have a free-text comment, which can be shown or hidden as desired.
