We’re big fans of Notegraphy, with its fancy typefaces and myriad formatting options, but iAWriter is a completely different beast. Think Notepad on Windows and you already have a good idea.
iAWriter focuses on the act of writing, ignoring the difficulties that come with formatting on mobile devices. It even has a focus mode that forces you to concentrate on your current sentence. Everything syncs automatically to Dropbox, letting you fiddle later if that’s how you roll. $6.67, IA.NET
