There is an app, website, or software platform for just about anything. But when it comes to outlining your book, there is one app I can't live without: iThoughtsHD.
Here's why.
It's a mind-mapping tool. The most effective way to collect your thoughts visually.
It works across platforms. iPad (where I typically start), iPhone (if I need to make updates on the go), and Mac (where I move from mind map to outline).
It's fast. I've been using it for over ten years, and I'm trying to remember it ever running slow.
It has templates. Having done this many times, I can now start from a template.
It's universal. It uses OPML to import and export from other tools.
And the number one reason: it uses keyboard shortcuts, so I can quickly create the structure without my fingers leaving the keyboard.
