*** PLEASE NOTE: This NOT the meditation app! *** (There is another app called "Headspace: Guided Meditation and Mindfulness" and this is NOT that app!) This is the *original* Headspace! HEADSPACE is iOS's coolest 3D outliner and mind-mapping app! Do your list-making and mind-mapping in 3D space with the *original* Headspace. "Five stars on iPhone, completely off the scale on iPad" "This is the app I've most wanted to run on the iPad since the day it was announced, and the app that anyone looking over your shoulder will immediately want to buy an iPad just to run. " "Love the program. Favorite app. Useful and looks great. " "The implementation is beautiful! In my opinion, Headspace is becoming one of the best apps in the store." "I bought Headspace last night on a whim - been fooling around with mindmapping apps lately. This is a little piece of brilliance, you know that, right? " "This app could not just be a mindmapping program, It has the capability to become a new kind of U.I. That in my opinion that improved over apples U.I." Headspace allows you to create items and groups of items on a floating plane in three-dimensional space. The hierarchy of items and their various sub-items make for a beautiful display of information as they recede into the distance. Simple and familiar finger gestures allow you to move around the space. Use the menu button to travel between various groups. Easily create links and travel between them. The beautiful animated interface is like something from a sci-fi movie, but it isn't just eye-candy. You can go from an "eagle-eye" view of your entire map to focusing on a single item with a simple pinch of your fingers. There's just something about being able to manipulate the scale and space that goes perfectly with the idea of outlining. Here's a rundown on all its cool features: ● build hierarchical outlines in 3D space ● use familiar finger gestures to navigate and zoom ● connect related items with link lines - even between files! ● change item color and opacity ● change text color ● 'Flick' up or down to travel to top or bottom of lists ● special characters and foreign-language support ● universal app -- runs on both iphone and ipad ● easy travel between groups and files ● cut-and-paste items ● search in spaces, notes, and files ● item notes for supplemental information (text/photo/url) ● optional accelerometer rotate ● customizable color palette ● "to-do" style item checkboxes ● 2D orthogonal mode ● sync files between your iphone and iPad with Dropbox ● file support for Freemind, the free multi-platform desktop mind-mapping program ● stunning PDF export w/ active note links Get some perspective on your thoughts.

The infinite mind map for iPhone & iPad: millions of connected ideas in a single file. Traditional mind mapping tools hit their limits at 50 to 100 nodes and force you into a rigid tree. InfoRapid KnowledgeBase Builder is a true knowledge network for personal knowledge management and your digital "second brain": any item can be linked to any other, every connection carries its own label, and your database grows to millions of entries without becoming cluttered. Just like in Google Earth, you always see exactly the area you are interested in – a tap smoothly centers any item. SPECTACULAR 3D VIEW Experience your knowledge in space: the interactive 3D view arranges your network as a sphere, an orrery or a planetarium. Fly from item to item with smooth camera moves, or let presentation mode take you on a guided tour – perfect for talks, teaching and videos. WHITEBOARD, MIND MAP AND KANBAN IN ONE APP Start freely on the whiteboard: ideas, notes and tasks float on an infinite canvas. As your thoughts take shape, arrange them as a mind map with one tap – or as a Kanban or Scrum board for projects and tasks. Drag a card into the next column with your finger or Apple Pencil and its status follows automatically. TIMELINE FOR DATES AND DEADLINES Give every item a start, end, due date, status, priority and owner. The timeline shows your whole project at a glance; drag a bar with a swipe to reschedule, tap it to open the item. EVERY DIAGRAM TYPE, AUTOMATICALLY ARRANGED Connect items by drag and drop using touch or Apple Pencil and label every relationship. A single tap arranges the whole network radially, symmetrically, hierarchically or as a table. Create mind maps, concept maps, flowcharts, org charts, family trees and even mathematical formulas (LaTeX). The app can also draw flowcharts straight from pseudocode. NOTES, RICH TEXT AND ATTACHMENTS Every item holds more than a title: formatted notes with tables, checklists and links to other items. Attach PDFs, Word and Excel files, images or web links directly – with automatic previews. FULL-TEXT SEARCH INSIDE YOUR DOCUMENTS The lightning-fast search finds not only item names but also the text in your notes and attached documents. OPTIMIZED FOR TOUCH & APPLE PENCIL Interact with your knowledge base naturally and fluidly: navigate with pinch-to-zoom, draw and connect thoughts directly with your finger or Apple Pencil. Whether on the go with your iPhone or on the expansive canvas of the iPad Pro, the interface adapts effortlessly to your device. WIKIPEDIA, WIKIDATA AND OBSIDIAN IMPORT Search Wikipedia or Wikidata right inside the app and turn entire articles, including their relationships, into a ready-made mind map. Text analysis automatically extracts the key terms from your own texts. Complete Obsidian vaults can be imported, too. CATEGORIES, TAGS AND FILTERS Group items by color and topic and hide entire branches with a single switch. ALSO INCLUDED • Learn with flashcards: the app turns your mind maps into flashcards and cloze tests for school, university and work. • Undo without worry: up to 200 steps are kept – even after a restart. • Open formats: import and export as JSON, XML, CSV, text document, image or 3D model. • Your data stays with you: every knowledge base is a fast SQLite file (.kdb) stored directly on your device. 100% offline, no account, no cloud lock-in, no tracking. • Seamless sync via iCloud Drive: share and edit the exact same .kdb file across iPhone, iPad, and your Mac or PC.
