What OmniOutliner is
OmniOutliner organizes information as outlines that you can develop and rearrange to clarify ideas. Outlines can have unlimited levels, expandable sections, status checkboxes, and row notes. Pro adds multiple columns for values such as text, numbers, dates, durations, checkboxes, and pop-up lists. Writing options include Distraction Free and Typewriter modes, with optional row, word, and character counts. The app imports OPML, plain text, RTF, RTFD, and earlier OmniOutliner files. It exports CSV, HTML, Dynamic HTML, OPML, plain text, and RTF; Pro adds DOCX, PPTX, and XLSX. Documents can sync through iCloud Drive or OmniPresence, and flat files can work with services such as Box, Dropbox, Google Drive, and OneDrive. The maker says documents remain on-device by default and users control where synced data is hosted. It works offline on Apple platforms. Essentials costs $24.99 USD once; Pro is $99.99 USD once or available by subscription for $49.99 a year. A 14-day trial is available, but there is no free plan.
