Scrivener for iPad and iPhone allows users to compile writing projects into various file formats with basic default templates, including Manuscript, Modern, Palatino Book, and Script formats. While customization options are more limited than on desktop versions, users can edit compile formats using simple YAML text files called .scomp files, enabling detailed control over formatting such as font, spacing, chapter numbering, headers, footers, and page breaks. This advanced editing approach requires some learning but offers many of the same formatting capabilities available on Mac and Windows, allowing writers to tailor their exported documents precisely.

John Degen, author and head of The Writers’ Union of Canada, wrote his latest novel, Seldom Seen Road, entirely on his iPhone using Scrivener, utilizing daily commutes to maintain a consistent writing routine. The novel features a detective trio set against the vast wilderness of northern Canada, where the landscape acts as both a character and an omnipresent threat, reflecting Degen’s deep connection to his environment and interests like birding. He also addresses issues of authors’ rights amid AI training data concerns and plans to create a writing shed to further separate his imaginative work from daily life.
