ReadSync remembers where you stopped reading โ€” on every device. Open a PDF on your Mac, read to page 120, then pick up your iPhone. ReadSync opens the same document on the same page. Your highlights, notes and bookmarks are already there. WHY READSYNC โ€ข Your reading position syncs automatically through iCloud โ€” in the free version too โ€ข No account to create, no subscription, no company server holding your files โ€ข Works completely offline โ€” syncing is a layer on top, never a requirement PICK UP WHERE YOU LEFT OFF โ€ข A Continue Reading row at the top of your library, most recent first โ€ข A Home Screen widget that opens the document on the page you left โ€ข Nothing to press: the page is saved as you read and travels with you โ€ข Handoff: the document open on your Mac appears on your iPhone, and opens on the same page READING โ€ข A quiet reader that hides its controls while you read โ€ข A reading lock that turns off selection, highlights and notes, so you can scroll and zoom without triggering anything by accident โ€ข Keep the screen awake while a document is open โ€ข Night mode that darkens the page without draining the colour from your highlights โ€ข Single or two-page layout, vertical or horizontal scrolling โ€ข Adjustable default zoom โ€ข Translate any passage you select into your own language, on your device with Apple's built-in translation โ€ข Look up any word in the dictionary without leaving the page โ€ข Password-protected PDFs open too โ€” remember the password once, in your iCloud Keychain, and your other devices open them without asking HIGHLIGHTS AND NOTES โ€ข Five highlight colours โ€ข Attach a note to any passage โ€ข Every highlight and note in one list โ€” tap to jump straight to the page โ€ข Export everything from a document as a single file, to Notes, Mail or Files โ€ข Nothing is written into the PDF itself; your original file stays untouched FINDING YOUR PLACE โ€ข Full-text search inside the document โ€ข The PDF's own table of contents โ€ข Bookmarks for the pages you want to come back to YOUR LIBRARY โ€ข Add files from Files or iCloud Drive โ€ข Open a PDF in ReadSync from Mail, Safari, Messages or any app's share sheet โ€ข Leave a file where it is, or copy it into ReadSync so it syncs across your devices โ€ข Cover, progress and page count at a glance โ€ข Sort by last read, title or date added โ€ข Search your library by title READING STATS โ€ข Total reading time, and how much of it was this week โ€ข A chart of the last seven days โ€ข Progress for every document you have started FREE AND PRO The free version is a whole reader, not a demo: iCloud sync, night mode, search, table of contents, bookmarks, translation and all five highlight colours, with room for 5 documents and 10 highlights or notes in each one. ReadSync Pro lifts both limits and opens reading stats and note export. It is a one-time purchase โ€” there is no subscription. A limit only ever stops you adding something new. Everything already in your library stays open, in full, whether you buy or not. PRIVACY ReadSync is built entirely with Apple's own frameworks and stores everything in your private iCloud database. Your documents are never uploaded to anyone else's server. Anonymous usage statistics are sent only if you agree when asked, and never include your files, page contents, notes or highlights.
