ReadSync
Read full descriptionHide full description
ReadSync remembers where you stopped reading ā 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 ⢠Your reading position syncs automatically through iCloud ā in the free version too ⢠No account to create, no subscription, no company server holding your files ⢠Works completely offline ā syncing is a layer on top, never a requirement PICK UP WHERE YOU LEFT OFF ⢠A Continue Reading row at the top of your library, most recent first ⢠A Home Screen widget that opens the document on the page you left ⢠Nothing to press: the page is saved as you read and travels with you READING ⢠A quiet reader that hides its controls while you read ⢠Night mode that darkens the page without draining the colour from your highlights ⢠Single or two-page layout, vertical or horizontal scrolling ⢠Adjustable default zoom ⢠Translate any passage you select into your own language, on your device with Apple's built-in translation HIGHLIGHTS AND NOTES ⢠Five highlight colours ⢠Attach a note to any passage ⢠Every highlight and note in one list ā tap to jump straight to the page ⢠Export everything from a document as a single file, to Notes, Mail or Files ⢠Nothing is written into the PDF itself; your original file stays untouched FINDING YOUR PLACE ⢠Full-text search inside the document ⢠The PDF's own table of contents ⢠Bookmarks for the pages you want to come back to YOUR LIBRARY ⢠Add files from Files or iCloud Drive ⢠Leave a file where it is, or copy it into ReadSync so it syncs across your devices ⢠Cover, progress and page count at a glance ⢠Sort by last read, title or date added READING STATS ⢠Total reading time, and how much of it was this week ⢠A chart of the last seven days ⢠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, note export and the widget. It is a one-time purchase ā 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.
Panoo

Panoo turns your notes into something you actually want to look at: colorful paper notes, pinned to a warm cork board. Write a note, choose its paper, its pattern and its pin, then drag it anywhere on the board. It looks like the board above your desk, and that is exactly the point. Notes you can see are notes you remember. A REAL WIDGET, NOT A SCREENSHOT You choose which note goes on your Home Screen. Add several widgets and give each one a different note. Edit the note and the widget updates itself. Small, medium and large on iPhone, plus an extra large size on iPad. IT SYNCS BETWEEN YOUR DEVICES Turn on iCloud sync and your notes and boards move between iPhone and iPad on their own. There is no server of ours in between: the data sits in your own iCloud storage. Leave it off and Panoo keeps working completely offline. YOU BUILD THE BOARD ⢠7 frame designs: plain wood, classic moulding, rope, aluminium, carved and more ⢠16 frame colors and two corner shapes, so hundreds of combinations ⢠15 paper patterns: plain, lined, grid, stripes, zigzag, hearts, stars ⢠12 pins: classic thumbtacks, glass beads, flowers, stars, even a little cat ⢠9 color palettes for your paper ⢠4 fonts, including handwriting ⢠Light and dark theme, both free MORE THAN A PRETTY BOARD ⢠Checklists: ticked items get a line through them, visible right on the board ⢠Mark a finished note as done and spot it on the board at a glance ⢠Reminders: a notification at the exact time you choose ⢠Several boards: keep work, home and shopping apart ⢠Pinch a note to resize it, twist it to any angle ⢠Share any note as an image ⢠Landscape on iPhone, and the whole app rotates on iPad BUILT FOR ⢠Anyone who keeps paper sticky notes on a desk ⢠People who live off shopping lists and to-do lists ⢠Students and workers who want class, meeting and idea notes in plain sight ⢠Anyone who wants a Home Screen worth looking at YOUR NOTES STAY YOURS No account. No sign-up. No ads, not one, in any form. Panoo never sends your notes to a server of ours. With iCloud sync on, the data only goes to the iCloud storage of your own Apple Account. FREE AND PREMIUM Panoo is free to use, and the free version is not crippled: unlimited notes, unlimited boards, unlimited reminders, iCloud sync, light and dark theme, 5 paper patterns, 3 pins, 3 frame designs, 4 frame colors, 2 palettes, 2 fonts and one widget note. Panoo Premium unlocks the rest: every pattern, pin, frame design and frame color, every palette and font, and as many widget notes as you want. Premium is a one-time purchase, not a subscription. Pay once and it stays yours; restore it any time on any device signed in to the same Apple Account.

Verdict
The clearest difference is update cadence: Panoo at every 3 weeks against ReadSync's every 2 months. Panoo also leads on iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
