On a recent episode of Hacker Public Radio, the host, Lee listed several note-taking apps that he had tried to use. One of them was Joplin which I have been using for several years now. I feel that it is probably one of the best note-taking apps available that:

• Supports Markdown
• Is cross-platform
• Supports vim keyboard mappings (I can’t live without this)
• Integrates with multiple cloud storage environments.

I use it on a daily basis for almost all of my notes but it also supports checklists on my iPhone, iPad, Windoze laptop, and all of my Slackware devices (desktop and laptops). Give it a try!
