What Outliner by Alfred Fritz is
Outliner by Alfred Fritz organizes shopping lists, tasks, ideas, memos, and small projects as collapsible tree structures on Android. Users can create unlimited outlines, each containing titled activities with notes and due dates. Outlines can be viewed as trees, to-do lists, due-date lists, or hashtag-grouped lists, although some views require PRO. Activities can be reordered and indented; PRO adds subtree cut, copy, paste, sorting, and sharing. PRO search can find terms in activity names and notes, while formatted notes support bold, italic, font color, and font size. Sync options include Google Tasks and Dropbox, with the tutorial also documenting Treeline and OPML synchronization. The app imports CSV, Natara Bonsai, Treepad HJT, Treeline TRLN, OPML, and plain text; PRO adds HTML export. The free version has no ads and no sync. PRO features are unlocked by separately installing the Outliner Pro Key app, listed at $5, paid once. The maker says outlines are stored locally unless cloud sync is configured.
