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 or a single PDF 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.

About

TextEditS

Features
Read full description

TextEditS opens the text files already on your device, edits them, and saves them back where they were. Nothing is copied into the app. It is built for the moment you need to fix a config file on the move, check a log on site, or reopen a note written years ago. ■ The rule for an app that touches your originals Files are never copied into the app. Open, edit, save in place. Until you press save, the original file does not change. If another app modified the same file while you were working, you are told before you overwrite it. ■ Nothing is lost when you don't save If the app closes while you are working, your tabs and unsaved edits come back exactly as they were. Unsaved work is kept in the app's private storage, entirely separate from the original file. Saving happens only when you ask for it. ■ Encodings handled properly EUC-KR, CP949, Shift_JIS, GBK and Big5 files are detected and opened correctly, including extended Korean characters. You can also choose an encoding and reopen the file, and if a character cannot be written in the encoding you picked, you are warned before the file is damaged. Line endings (LF/CRLF) are preserved as they were. ■ Everything you need to edit • Open several files as tabs and move between them. • Find and replace with match case, whole word and regular expressions. Replace All is a single undo away. • Line numbers on the left, with line marks you can tap and jump between. • An outline of functions, classes and headings for quick navigation. • Document tools: sort, remove duplicate or blank lines, adjust indentation, convert case, count words. • Auto indent and bracket completion that stay out of the way while you type in Korean, Japanese or Chinese. ■ File management and other apps Rename, move, copy and paste, and create folders without leaving the app. Non-text files are not opened in the editor; you are offered to open or share them with another app instead, because opening a PDF here would garble it and saving would destroy it. ■ A comfortable place to read Nine themes including Light, Dark, Sepia, Paper, Black (OLED), Solarized and Monokai, with adjustable font size and line spacing. Available in Korean, English, Japanese, Simplified Chinese and Traditional Chinese. ■ Your file contents never leave the device The contents, names and folder paths of the files you open are never transmitted. There is no account, no login and no advertising. ■ More from Solution317 • MalssmMoa — Daily sermon streaming • BibleS — Read and remember Scripture • WeatherKoreaS — Korean weather at a glance • CopyNPasteS — Save phrases, paste them in one tap • MyNoteS — A safe, local-only notepad • PdfToImageS — PDF to images, safely offline • ResizeToS — Resize a whole folder at once • PhotoRenamerS — Rename photos by capture time • VolumeControlS — Media volume in 10% steps made by Solution317
