Outliner by Alfred Fritz is an Android app for arranging shopping lists, tasks, ideas, memos, and small projects as nested outlines. Each outline can contain titled activities with notes, due dates, and completion status, and users can create as many outlines as they need. Activities can be reordered and indented. Outlines can be displayed as a tree, a to-do list, a due-date list, or a list grouped by hashtag; some views require PRO. The free version provides basic features with no ads and no synchronization. PRO features require installing the separate Outliner Pro Key app, available for a one-time $5.00 USD purchase. PRO adds activity search, formatted notes, subtree editing and sorting actions, sharing, and synchronization with Google Tasks and Dropbox. The app can import CSV, Natara Bonsai, Treepad HJT, Treeline TRLN, OPML, and plain text; export options include those formats, with HTML available in PRO. The maker says outlines remain on the device unless cloud sync is configured. It is listed for Android phones, tablets, and Chromebooks, with no desktop app.
Who it is for
Outliner suits Android users who want to organize tasks, lists, notes, or small projects in nested outlines and view them by tree, due date, to-do status, or hashtag. People who need sync, search, formatted notes, or other PRO tools can add the separate key app; the free version is aimed at basic use without synchronization.

Verdict
Pick Outliner if you want an Android app for organizing nested lists and small projects, and the free basic version meets your needs. Consider another option if you need a desktop app or synchronization without paying for PRO; Google Tasks sync is limited to two levels of tasks and subtasks.
