I wrote an article a while ago about The Tools I Use: Writing and Text Apps, discussing the different apps that are part of my writing toolbox.
In my latest Macworld article, I look at several “focused-writing” apps for OS X. “These apps, increasingly popular of late, allow you to write in a focused environment, export your writings to various formats, possibly apply basic styling, and let you print your work.”
I have tested many of these over the years, and, while my choices may not match yours, it’s worth looking at what’s available. I picked several that I like a lot, and it’s safe to say that there’s no shortage of excellent apps in this category for OS X.
