Writer supports OS X’s built-in spell checker, and in the footer of the Writer window are a few basic document statistics. And if you want formatting without Markdown, you’re out of luck. Formatting characters disappear only when you export a file to RTF and open it in another program. The drawback is that while surrounding text with asterisks, for example, does indeed underline it, the asterisks remain visible, as well, which can be confusing. The advantage of using Markdown for an app such as iA Writer is that you can apply formatting without having to use any menus or buttons (though you can use standard formatting keyboard shortcuts-Command-U for underline and Command-B for bold-and Writer will apply the asterisks for you). If you must have formatting, iA Writer uses Markdown syntax for, for example, underlining (asterisks around text), bold (double asterisks around text), and headers (one or more # symbols)-add these control characters and the formats are immediately applied to the designated text. I would prefer if focus mode would at least highlight several sentences before and after the active one, if not the entire paragraph containing the active sentence.

Just as atoms have value only when they form molecules, individual sentences are meaningful mainly when combined with other sentences-they depend on the surrounding text for context. To use a chemistry analogy, a sentence is an atom and a paragraph is a molecule. Few writers that I know actually write sentence by sentence. Personally, I wasn’t a fan of focus mode. The program even provides keyboard shortcuts (Command-Option-left arrow and -right arrow) to navigate from sentence to sentence. According to the developer, this mode allows you to focus on the specific text you’re actively writing. In other words, the sentence you’re typing is displayed in black, with the rest of the text in a medium grey.

The second feature is “focus mode,” which, when active, dims all the text in your document except the current sentence.
