OutlineProcessor is an iPhone outline editor built around hierarchical nodes. Add items, move them up or down within a level, indent them under a parent, or outdent them back up — all with simple arrow buttons. Multiple documents are supported, and every edit saves automatically so nothing gets lost.
Items (nodes) live in a collapsible tree structure that can go as many levels deep as you need. Indent a node to make it a child of the item above, outdent it to move it back up the tree. Complex information becomes easy to navigate once it has the right structure.
Four arrow buttons — up, down, left, right — let you move the selected node in any direction. Up and down reorder within the same level. Right indents (makes it a child). Left outdents (moves it to the parent level). Drag-to-reorder is also supported for quick adjustments.
The File List tab lets you create, switch between, and delete outline documents. Tap the + button to start a new document, and tap any file in the list to switch to it instantly. Keep separate outlines for different projects, topics, or contexts.
Typing, moving nodes, renaming a document — every action is saved to disk automatically. There is no save button to tap and no risk of losing work when you switch apps or close OutlineProcessor. Your outline is always up to date.
A single tap selects a node and activates the arrow controller so you can move it immediately. A double-tap opens a text editing dialog where you can modify the node's content and confirm with the Save button. The selected node is highlighted so it's always clear which item you're working with.
The arrow controller appears at the bottom of the screen — or at the top if the selected node is near the bottom — so it never covers what you're editing. Up and down move the node within its current level. Right indents it under the node above. Left outdents it to the parent level. Restructuring a complex outline takes seconds, not minutes.
Tap the File List tab to see all your outline documents in one place. The + button in the top-right corner creates a new document with a default title — rename it any time. Tap a document to jump to it in the editor. Swipe to delete documents you no longer need.
First launch opens a sample document that shows how the hierarchy works at a glance. Tap + to add a node, double-tap to set its text, and use the arrows to place it where it belongs. No tutorial required — the interface shows you what to do.
Tap the + button in the top-left corner of the editor to add a new node at the bottom of the outline. Double-tap the new node to open the text editing dialog and enter your content.
Tap any node once to select it. The node highlights to confirm the selection, and the four-arrow controller becomes active and ready to use.
Up and down arrows reorder the node within its current level. The right arrow indents it as a child of the node above. The left arrow outdents it back to the parent level. The controller positions itself above or below the selected row automatically.
"I use this every day for meeting notes and project planning. The indent and outdent buttons make it easy to restructure the hierarchy on the fly, and automatic saving means I never lose anything when I switch apps mid-meeting. Exactly the tool I was looking for."
"I organize book notes in a three-level hierarchy — chapter, section, key point — and OutlineProcessor handles it perfectly. Being able to drag nodes to reorder them is a nice touch alongside the arrow buttons, and having a separate document per book keeps everything tidy."
"My workflow is to dump ideas in quickly and sort them later with the arrow buttons. I add everything that comes to mind, then use indent to group related items under a parent node once patterns start emerging. Simple app, but it fits how I actually think."
