CarbonFin Outliner vs Orgzly Revived

CarbonFin Outliner organizes thoughts, tasks, and projects in nested outlines. Tasks can contain subtasks, with progress indicators for parent tasks that have them. Its editor supports inline changes, cut, copy, paste, undo, redo, drag-and-drop reordering, search, and controls to collapse or expand items. Outlines can be tagged and filtered by tag, searched across the collection, archived, and optionally numbered. Each outline can include notes, with configurable checkboxes, note previews, and numbering. The iPhone and iPad app costs $4.99, paid once. Outliner Online is a free browser-based companion for syncing, editing, printing, importing, exporting, and sharing outlines. Outliner users can invite other Outliner users to view and edit shared outlines; published outlines can be viewed read-only by anyone with the URL. The app can sync outlines as OPML files with Dropbox or OneDrive, import OPML, and export plain text or OPML. Shared editing through Outliner Online is limited to iPhone or iPad app users. The app lacks native printing, though synced outlines can be printed through Outliner Online in a browser.

Orgzly Revived is a free Android outliner for notes and to-do lists. It stores notebooks as plain-text files in Org mode format, which supports both Org-mode import and export. Notes can include schedules, deadlines, priorities, and tags, while saved searches provide quick access and templates are supported. Notebooks synchronize with local directories, Dropbox, WebDAV, and experimental Git repositories. Synchronization is manual and starts when the user taps Sync. If local and remote notebooks conflict, the app offers force load or force save, without another in-app resolution method. Dropbox synchronization is available in the Google Play version but not the F-Droid version. The app is distributed through Google Play, F-Droid, and direct GitHub release APKs. Its privacy policy says it collects and shares no user data; notebook data remains on the device unless repository syncing is configured. Documentation publishes a SHA-256 signing checksum for APK verification.
