Summary

Outliner by Alfred Fritz organizes shopping lists, tasks, ideas, memos, and small projects into collapsible outlines. Each outline can contain titled activities with notes, due dates, and completion status, and users can create as many outlines as they need. The app offers tree, to-do, due-date, and hashtag-grouped views, though some views require PRO. Activities can be moved and indented; PRO adds subtree editing, sorting, and sharing, along with search and formatted notes. PRO also enables synchronization with Google Tasks and Dropbox. The app imports and exports several formats, including OPML, plain text, CSV, Treepad HJT, and Treeline TRLN; HTML export is a PRO feature. The free Android version has basic features, no ads, and no sync. It is free, while the Outliner Pro Key costs 5.00 USD per once and unlocks PRO features. The maker says outlines are stored locally and are not sent to external servers unless cloud sync is configured. Android is the listed platform, with no desktop app.

Who it is for

It suits Android users who want to organize tasks and notes in nested lists, especially those needing multiple outline views or file-format options. Users who want sync, search, or enhanced editing need PRO.

What is good

Create unlimited outlines with notes and due dates.
Several views include tree and due-date lists.
Free version has no ads and no sync by default.
Imports and exports multiple outline formats.

What to know first

PRO features require the separate Outliner Pro Key.
Google Tasks sync is limited to two levels officially.
SD-card and Dropbox backups are unencrypted.
No desktop app is listed.

Verdict

Outliner combines nested task organization with multiple views and broad import and export options. Its free version covers basic use, while sync and other advanced tools require PRO; backup encryption and Google Tasks depth are limitations to consider.
