Outliner by Alfred Fritz is an Android app for organizing shopping lists, tasks, to-do items, ideas, memos, and small projects in collapsible outlines. Each outline can contain unlimited titled activities with notes, due dates, and completion status. You can switch among tree, to-do, due-date, and hashtag-grouped views, although some views require PRO. Activities can be reordered and indented; PRO adds subtree cut, copy, paste, sorting, sharing, full-text search, and formatted notes with bold, italic, font color, and font size. Synchronization options include Google Tasks and Dropbox, with Treeline and OPML options documented in the tutorial. Imports include CSV, Natara Bonsai, Treepad HJT, Treeline TRLN, OPML, and plain text; PRO adds exports such as HTML. The free version has no ads and no sync. PRO requires the separate Outliner Pro Key app. Android is the listed platform, including phones, tablets, and Chromebooks.
