Kase exists because it should. There should be a database app that can go anywhere with you. It should be: • Simple — Using it should be easy and intuitive, • Flexible — Once familiar with the basics, you can design any database to track anything important to you, and • Relational — Inter-linked data is an order of magnitude more useful. Plus, you don't want to repeat yourself. Additionally, it should be: • Personal — You should not need to worry about who can peek into your data, and • Always Available — High-speed wireless network should *not* be a prerequisite for accessing your own data. Structured data at your fingertips. Something like that didn't exist, so I started creating Kase in 2014. Basic Concepts: • Your Kase contains Boxes. • Each Box stores Decks that can relate to each other. • A Deck collects similarly structured Cards. • And a Card is where you put data Entries. Features: • Pick, assign, and organize with Categories, Tags, and Marks. • Search by name, notes, full text, or keywords: Full-text indexing with Natural Language Processing. • Highlight any Box, Deck, Card, Entry, or Keyword. • Deck definitions support inheritance! • Field types include Text, Number (with Unit), Money (with Currency), Date/Time (with Time Zone), Choice, Boolean, Link, Picture, and Document. - complete with multi-level auto-conversion • Write in Markdown and see rich formatted text. • Box can be locked with a passcode, and unlocked with Face ID or Touch ID. • Formatters (Fx) to visualize data in different ways without altering the data one bit. e.g. Unit Converter, NameMapper, WordScrambler, ICU Transformers... • Side-by-Side: Compare Cards easily by displaying in columns. • On-device Text Recognitions (OCR) for multiple languages. • Import/Export in CSV, JSON, or KASE. • Complete Backup & Restore. • iPad Multitasking support: Split View, Slide Over, etc. • Very customizable UI with custom locales What Kase Can't Do: - Cloud sync is not done yet (stay tuned...) What Kase Can Do: > From Data to Wisdom > Data ▹ Information ▹ Knowledge ▹ Wisdom 1. Store Data — the objective truths. 2. Organize Information — to reflect circumstances and current condition. 3. Systematically retrieve Knowledge — utilized for decision-making. 4. And that hopefully enables you to grasp Wisdom, comprehend insights, and ultimately create value. There are databases that belong to the Big Guys. The rest of them should stay personal. By now, you should realize how valuable your data is. So why give it away? Kase keeps your data yours.

ghostWriter Markdown is an accessibility-first, plain-text writing app for notes, articles, documentation, and full manuscripts. Write individual documents, organize chapters, and compile your work into a finished export. VoiceOver was at the center of the design from the first line of code. Created by a blind developer, ghostWriter gives screen reader users and anyone who loves plain text a clean, native place to write. So what's Markdown? Markdown adds structure using ordinary punctuation. A number sign makes a heading. A dash makes a list item. Your document stays readable as plain text, and you can render it to see the finished formatting. You don't have to know Markdown to start. Insert Actions adds common elements, the Markdown Reference provides examples, and the included ghostWriter Help Manual explains writing, organizing, and exporting your work. Writing Made Easy: • A native editor that keeps Markdown punctuation visible and you in control of the source • Insert links, images, headings, quotes, code, lists, tasks, tables, and rules • Automatic continuation for bullets, numbered lists, and tasks • Indent and outdent with tabs or spaces • Native Find and Replace, dictation, braille input, and text selection • A configurable Status Bar with line and column position, word, sentence, and character counts, heading level, and selection counts • Automatic saving, plus collision detection if the same document is open on separate devices • Start in the Library, a new document, or your last document Useful Navigation: • Use Outline to jump to document headings • Move through headings with a three-finger horizontal VoiceOver swipe while editing • Jump to Line in long documents • Search document names and contents • Return to your remembered editing position in each file Keep Files Organized: • Create, rename, and move nested folders • Pin documents you keep coming back to • Sort by name, created, modified, or last opened, or arrange files and folders manually • Restore removed files from Recently Deleted • Import Markdown, plain text, Word documents, and PowerPoint presentations into Markdown Build Your Manuscript: • Compile documents from nested folders into a single export • Choose which files to include and arrange chapters for each compilation • Keep research and notes nearby while excluding them from compilations • Track word, sentence, and character totals for individual files or whole folders • Control heading structure when combining documents Render and Share: • Render Markdown as structured HTML with semantic headings, lists, tables, and links • Export individual documents or compilations as Markdown, plain text, HTML, EPUB, PDF, Word, PowerPoint, eBraille, or BRF • Customize Word exports with your own JSON stylesheets, optional title and subtitle styles, and a supplied Large Print stylesheet Your Files, Your Devices: • Ordinary Markdown files, visible in the Files app • On-device storage or iCloud Drive syncing across iPhone, iPad, and Mac • Open and edit your files in other apps that read text • No proprietary format and no dependence on ghostWriter to keep your work Accessibility: Developed toward WCAG 2.2 Level AA and tested with VoiceOver as a primary interaction method. • Native controls with familiar roles and behaviors • Dynamic Type, including accessibility text sizes • System, monospaced, rounded, and serif editor typefaces • Light, dark, and system appearance • Voice Control, Switch Control, and hardware keyboard support • Optional keyboard shortcuts for common actions • Reduced-motion support Privacy: No accounts. No sign-in. No ads. No analytics. No tracking. No data collection. No AI tools. There is no server behind this app. Your documents stay on your device or in your own iCloud, and they never travel anywhere you don't send them. Made by a blind developer who got tired of tools that treated screen reader support as an afterthought.
