Interesting new writing application for Mac. It won't be for everyone but I certainly welcome the approach to getting rid of preferences and all the annoying chrome that Word has foisted upon anyone hoping to type up a document.
iA Writer has no preferences. It is how it is. It works like it works. Love it or hate it. It’s unique FocusMode allows me to think, spell and write at one sentence at a time. iA Writer is fast; it works without mouse. It automatically formats semantical entities such as headlines, lists, bold, strong, block quotes written in markdown.
Check out the video preview and then check out iA Writer in the Mac app store. It's 10% off for a limited time. They also make a version of iA Writer for the iPad.
