Read full description

Carry your BibTeX libraries with you on your iPad and iPhone! A BibTeX library is a collection of bibliographic references (papers, books, reports, etc.), designed to work with the LaTeX typesetting system. Each library is stored in a specially-formatted text file (typically ending in .bib), which you can create with your favourite text editor. The References app gives you an easy way to browse through and interact with your BibTeX libraries. You can scroll, search, follow links, and view file attachments. In particular: - The app creates links from DOIs, MathSciNet references, ACM IDs, and of course URLs. - The app understands elementary LaTeX, so if your titles and/or abstracts contain markup or mathematics (and if your LaTeX is simple enough) then the app can display them nicely. - If you used BibDesk or JabRef to create your library, the app can view your file attachments (e.g., PDFs that you have attached to your references). - You can view references grouped by keywords, if you use the Keywords field in your BibTeX libraries. You can also view all of your smart/static groups from BibDesk, and your dynamic/static groups from JabRef. - The app supports BibLaTeX libraries as well as classic BibTeX. The References app can open BibTeX libraries from anywhere on your device. In particular, you can use iCloud Drive to keep them synchronised between your devices. This app is read-only, not an editor. It takes great care in helping you view and explore BibTeX libraries and their links and file attachments; however, it does not provide a way to modify your libraries. References is lovingly created by human hands. FILE ATTACHMENTS: To view file attachments (e.g., PDFs), the path to each file should be included in the corresponding entry in your BibTeX library. You can do this using the specially encoded Bdsk-File-* fields (as used by BibDesk), or the plain text File field (as used by JabRef). If you are writing your BibTeX files by hand, just add a File field giving the location of the attachment, such as File = {../PDFs/foo.pdf}. You can tell References where to find these attachments by linking folders in your app settings. The app will look for your attachments within these folders – for example, if you link your Documents folder then the app will be able to match the BibTeX field {../PDFs/foo.pdf} to a real location such as Documents/PDFs/foo.pdf or Documents/foo.pdf. The app is able to read attachments stored on your device, or on iCloud Drive, or on third-party providers including Box, Dropbox, Google Drive, Nextcloud or OneDrive. If you are having trouble viewing attachments from a third-party provider, please mail the References developer with the details.

Read full description

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.
