## What is SP Neuron Mobile?

SP Neuron is a clean, fast mind-mapping and outliner built for the way you actually think. Drop ideas onto an endless canvas, connect them, and let your thoughts organize themselves.

Key features:

- Infinite canvas — pan and zoom freely, with no limit on how large your map grows.
- Node cards — each one holds your thoughts; drag to rearrange, pinch to zoom.
- Smart connections — link nodes to make relationships clear at a glance.
- Built-in outline sidebar — jump to any node and fly to it smoothly with a single tap.
- iCloud sync — your maps stay in sync across iPhone and iPad, with full offline editing that resumes the moment you're back online.
- 7-language built-in manual — English, German, French, Japanese, Korean, Simplified and Traditional Chinese, ready the first time you open the app.
- Liquid Glass design — crafted for iOS 26 with a fluid, native feel.
- Dark mode — easy on the eyes, day or night.
- Command palette — reach power actions with a keystroke.

Whether you're planning a project, studying, or capturing a sudden burst of ideas, SP Neuron keeps it all in one calm, beautiful space.

Privacy: SP Neuron does not collect any personal data. Your maps are stored only on your device and in your own iCloud container. There are no third-party trackers or ads, and you can delete your data or stop syncing at any time.


## Version history (last 5 releases)

### 1.5 — 2026-09-26

Neuron 1.5

New
- Markdown import: You can now import .md outline files. Hierarchy and notes are detected automatically, fully symmetric with the app's Markdown export for lossless round-trip.

Improved
- Automatic format detection on import: TXT and Markdown are now recognized automatically—no need to pick a file type manually. Indentation detection is more accurate, supporting 2-space, 4-space, and Tab mixed indents.
- Markdown syntax compatibility: Import now supports # headings, ordered lists, task lists, blockquotes, and code fences. Hierarchy no longer breaks and node notes are no longer lost.

### 1.4 — 2026-09-10

Neuron 1.4

New
- User Manual: a complete in-app manual in 7 languages, following your system language.
- Third-Party AI Prompt: long-press New Project in the filmstrip to copy a ready-made AI prompt, then bring the generated outline back in.
- Import Outline as New Project: long-press New Project and choose Import to create a project from a .txt outline, named after the file.
- iPad Toolbar: new Outline button; Command Palette and Search grouped into one pill; Quick Edit, Multi-select and Move grouped together.
- Outline Images: multiple images and image stacks now expand into a grid (up to 4 per row), loaded at display size, no mix-ups when zooming.

Improved
- Camera is remembered: leaving a project now saves canvas position and zoom even when nothing was changed.
- .txt Outline Import: all nodes expand, notes open for the nodes that have them, and everything is laid out in the current arrange style.
- Purchases & Activation: fixed no response when tapping Buy on a bad network, staying activated after signing out of a test account, and silent verification failures; no more unactivated flash at launch.
- Long Titles: fixed the scrolling title pushing the checkbox and +/− buttons out of the card.
- Outline Image Nodes: no title or note editing fields, matching Mac.
- Unified iPad toolbar spacing.
