Lectio Markdown / PDF Reader
Google Drive, iCloud, OneDrive
Free · Designed for iPad. Not verified for macOS.
Your cloud PDFs on one shelf, on iPhone and iPad. Spreads, right-to-left binding, contents and bookmarks let you read comics and papers like books, where you left off.
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.
