Organize your PDFs, set custom covers, and choose from several theme colors and icons, for a pleasant reading experience just the way you want it. • Create folders and folder groups to keep your PDFs organized however you prefer. Rename and rearrange things as the mood takes you. Name every single book and folder the same thing, if you really want to! (I don’t recommend doing that, but nonetheless, that’s the sort of awesome power that you wield if you use BookFolder.) • Set custom cover images for every book (or stick with a book’s default cover, of course). Your library will look the way that you want it to! (And the underlying files remain pristine, so if you begin to regret choosing a photo of your cat for every book in your collection, you can always restore the originals and no one will know. Except your cat, who is judging you now.) • Get wild on an iPad with split-screen multitasking support. Read two books at once (or the same book twice)! If that’s something that you want to do. • Swap between five theme colors, for an interface that works best for you. (Dark Mode support, too, of course!) • Choose from a dozen icons, from solid colors to subdued platinum to a retro rainbow look, to fit your mood and to ensure a harmonious home screen layout with your other apps. (I’m not the only one who arranges my icons by color and design… am I?) • You can use it to actually read the PDFs, too, of course. Mustn’t forget that part. • Plus bookmarks, searching, and table-of-contents support, as one would expect. • Also, it’s free, no in-app purchases, no tracking… just a nice PDF reader and library manager. I hope that you’ll enjoy it!

About

Lectio Markdown / PDF Reader

Features
Read full description

A bookshelf for your PDFs and Markdown files, on iPhone and iPad. Bring in files from the cloud or the Files app, turn their pages in two-page spreads, and write on them with Apple Pencil. Made for you if • You want to read scanned books and comics in spreads, the way you read them on paper • You read papers and documents and want to write notes on them with Apple Pencil • You keep notes, AI chat logs or READMEs in Markdown and want to read them calmly, page by page • Your PDFs are scattered across cloud services and you want them on one shelf Collect: PDFs and Markdown on one shelf From "Add Books", bring in files from any place that appears in the Files app, such as iCloud Drive, Google Drive, OneDrive and Dropbox. You can also open Lectio from the share sheet in another app, or drag and drop files onto the shelf. A Markdown (.md) file becomes an A4 PDF with its headings, lists, tables and code laid out, and takes its place on the shelf. The same file is never added twice, and password-protected PDFs can be added too. Books are kept on your device, so you can read them without a connection. Lectio only reads your cloud files and never changes or deletes them. Read: turn pages like a book Each book remembers its layout (two-page, single page or vertical scroll) and its left or right binding. Right-bound books lay out their spreads from right to left, so comics and vertical text read in their natural direction. Swipe or press the arrow keys to turn the page, and tap the page to hide the buttons. Lectio remembers where you stopped, so the next time you open a book you carry on from there. Switch the page color to night or sepia, adjust the brightness, and keep the screen on while you read. Write: Apple Pencil and four highlight colors Turn on Handwriting in the toolbar and a tool palette appears. Write directly on the page with Apple Pencil or your finger, choose pens, colors and the eraser, and your writing stays with each page. Highlight text in yellow, green, pink or blue, and find your highlights again under Highlights in the sidebar. Press and hold text to copy it, look it up or search the book for it, and tap links on the page. Find: contents, thumbnails and text search Jump to a chapter from the table of contents, or to any page from the thumbnail grid or by its page number. Search the text of a book and each match is highlighted in yellow. Books made from Markdown are searchable too. In the library, find books by name. Organize: favorites, bookmarks and collections Each cover shows how far you have read: New, a percentage, or Finished, and you can sort by Recently Read. See your favorite books, bookmarked pages and highlights in lists. A bookmark keeps the opening words of its page, so you know where you left it. Sort books into collections and arrange them in any order you like. Rename books, or select several to share them, add them to a collection or delete them in one go. Deleted books stay in Recently Deleted for 30 days, where you can bring them back. Widget, Spotlight and Handoff The Home Screen widget shows the books you read recently, and tapping one opens it where you left off. Search for books in Spotlight by name or by words in the text. With Handoff, pass the book and page you are reading to another iPhone or iPad that has the same PDF. iPhone, iPad and iPhone Duo Lectio supports iPhone Duo. Read on the outer display when it is closed, and in spreads on the large inner display when you open it. The buttons sit in the vertical bar along the edge, out of the way of the page. Keyboard, remotes and VoiceOver Press ⌘O to add books, ⌘F to search, ⌘B to bookmark and ⌘W to close. Pages turn with the arrow keys, so a Bluetooth keyboard or a page-turner remote that sends arrow keys works too. VoiceOver and Dark Mode are supported. You can also share and print your books. Start by tapping + in the library and add your first book.
