Inkiostro is a Markdown editor for people who write — notes, documentation, theses, novels. Plain text files that stay yours, a preview that looks like a finished page, and exports ready to hand over. Write in Markdown, or in the visual editor and never see a symbol. Buy once, no subscription. No account, no tracking. WRITE, SEE, FINISH • Two ways to write: the Markdown editor shows the symbols, the visual editor formats as you type, like a word processor. Either way the file stays plain Markdown. (Visual editor: Pro, free for 7 days) • A complete Markdown toolbar: headings, lists, tables and code blocks, one tap away. • A side-by-side preview that comes back exactly where you left it. • LaTeX formulas typeset by KaTeX, and Mermaid diagrams drawn as you type. • 27 preview styles, 11 of them free: GitHub, Sepia, Nord, Solarized and more. With Pro, Manuscript, Book, Report, Academic and others set the page like print. • Focus and Typewriter modes, a live word count and a daily writing goal. FROM DRAFT TO BOOK • PDF with selectable text, formulas and diagrams included. Free, with a small credit line in the footer. • A professional ePub: real chapters, a cover, ISBN, series, footnotes that open over the page, and the accessibility declaration Europe requires. The export sheet tells you what a store would reject — before you send it. (Pro) • A book made of many files: one chapter per file, in a folder, in the order you choose. Arranging it is free; exporting it as a single ePub is Pro. • Self-contained HTML, and page setup for PDF: paper, margins, headers and page numbers. (Pro) NEVER LOSE A WORD • Version history: Inkiostro saves versions as you write. Search them, compare them line by line, and bring back a single word or a whole draft. (Pro) • Backups of your whole library: a dated zip archive with your version history inside, offered when one is due, while the app is open, in a folder you pick. Open it in the Files app and your Markdown files are right there. (Pro) YOUR FILES, YOUR RULES • Unlimited documents, as plain .md files you can open anywhere. • Folders, color labels and tags, with search that filters by tag. • iCloud Drive sync between iPhone, iPad and Mac, with no setup. • External folders: work directly inside any folder on your device or in iCloud Drive. (Pro) INKIOSTRO PRO — ONE PURCHASE, EVERY DEVICE One purchase unlocks Pro on iPhone, iPad and Mac, forever. Try it free for 7 days. • The visual editor • Version history with search, comparison and a year of versions • Backups of your library • Professional ePub, HTML, and books made of many files • PDF page setup • Focus and Typewriter modes • External folders • 24 app themes, the Pro preview styles and any font installed on your device MADE FOR • Writers: novels and essays in plain text, out as a real ebook • Students and researchers: notes and theses with proper formulas • Developers: READMEs, documentation and technical notes with diagrams • Anyone tired of paying every month for a text editor • Anyone new to Markdown: the visual editor works like a word processor PRIVACY Your documents stay in your iCloud Drive or on your device. No servers of ours, ever. Inkiostro collects only anonymous, aggregated usage statistics — never personal data, never the content of your documents — and you can turn them off in Settings.

SteelNote is a notes app built on one promise: your notes are plain Markdown files that you own. Every note is a real .md file on your device, openable in the Files app or in any editor you like, today and years from now. No proprietary database. Nothing locked away. Your notes, truly yours. Because every note is plain text, you are never trapped. Read and edit them in SteelNote, in Files, or in any other Markdown app. If you ever move on, you take your files with you as they are, in an open format that lasts. Native on all your Apple devices. SteelNote is built natively for iPhone, iPad and Mac. Your notes sync across all of them through iCloud, with no third party account and no extra sign in. Start a note on your phone and finish it on your Mac. Find anything, instantly. A local full text index makes search immediate, even in large libraries. Link notes together, see backlinks, organize with folders and tags, and turn any line into a task. Private when you want it. Mark a note as private and it stays out of widgets and AI features. Your most sensitive notes remain yours alone. Bring everything with you. Import from Bear, Notion, Obsidian and Evernote, or from Markdown, TextBundle, Word, RTF, PDF and CSV files. Your folders and structure come along. Apple Notes works too, one note at a time, because Apple offers no bulk export. Everything you expect. Add images, PDFs and tables inline. Use checklists, footnotes and links. Reach your notes from Spotlight, Siri and widgets, and hand off between devices. An open format, now standard. Markdown is a first class type across Apple platforms, and SteelNote is built natively around it. Your files are open, portable and yours. Membership. SteelNote comes with a 14 day free trial, then a yearly plan or a one time lifetime purchase. You can cancel during the trial and pay nothing, or skip the subscription and choose the lifetime purchase instead. Sync is always included and never restricted. Payment is charged to your Apple Account. A yearly plan renews automatically unless cancelled at least 24 hours before the end of the period. You can manage or cancel anytime in your Account settings. Privacy Policy: https://steelnoteapp.com/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
