Finding a truly seamless sync can be a nightmare. From my testing, Kindle's own app remains the king for that specific feature, even if you sideload your own DRM-free EPUBs now. The progress updates almost instantly between my phone and tablet, and it even remembers where you stopped if you switch between the app and a physical Kindle device. The catch, of course, is the ecosystem lock-in, but for a free, reliable sync, it's hard to top.
Google Play Books also does a solid job for uploaded PDFs and EPUBs, though its reading features feel a bit more utilitarian.
If you stick with one of these major platforms, the headache of losing your place disappears.

For public domain classics, the Standard Ebooks project is amazing. They make beautifully formatted, free EPUBs. If you download one and put it in Google Play Books, you now have a gorgeous, synced copy of 'Pride and Prejudice' or 'Dracula' on all your devices. It's a fantastic combination of high-quality, free content and a free, syncing reading platform. Makes diving into the classics incredibly easy and pleasant.

I'm just sitting here waiting for someone to mention the one perfect app that does everything. So far, every suggestion has a 'but...' attached. I guess that's just the state of things. There's no unicorn. You pick the app whose strengths match your priorities and whose weaknesses you can tolerate. For me, that's been Moon+ Reader with Drive sync. The 'but...' is the slightly dated UI, which I don't mind at all.

I can confidently say that finding an app that syncs seamlessly across platforms is a game-changer. I've used apps like 'Libby' and 'Kindle,' and while both offer syncing, the experience varies. 'Libby' ties into your library card and syncs your borrowed books, but the interface feels clunky compared to 'Kindle,' which effortlessly keeps your progress, highlights, and notes in sync. The downside? 'Kindle' pushes paid content hard, and the free selection feels limited unless you're into classics or public domain works.
What really impressed me was discovering 'Moon+ Reader' on Android. It syncs with Google Drive or Dropbox, letting you upload your own EPUB or PDF files and pick up right where you left off on another device. The customization options are insane—fonts, themes, even scrolling animations. The catch? It's Android-only, so iOS users are out of luck. For a truly cross-platform solution, 'Google Play Books' is surprisingly solid. Upload your own books, and they sync flawlessly between Android, iOS, and even web browsers. The downside is the 100MB file limit, which can be a problem for heavily illustrated books.

Project Gutenberg has over 70,000 free ebooks, but their official app doesn't sync your library or progress. It's just a portal. Many people download from Gutenberg and then import the file into a syncing ecosystem. That's the two-step process.
There's a newer app called 'Serial Reader' that delivers classic public domain books in short, daily serialized chunks. It's a fantastic concept, and it syncs your subscription list and which day you're on across iOS devices via iCloud. It's not syncing a full library of arbitrary books, but for its specific purpose, it works seamlessly. It’s a good example of a free, niche app that built sync in by design.
For a more general solution, the app 'Pocket' can be used for reading articles and long-form web content, and it syncs perfectly. Some people save web novels or fic to Pocket. It's not a book app per se, but it handles progression sync for text you save from the web, which overlaps with the need.

The frustrating thing is when an app has sync but it’s buried in settings or doesn’t work reliably unless you have a constant internet connection. Good sync should be the default, obvious, and work offline-to-online seamlessly. You should finish a chapter on a plane, land, and have your progress update automatically when you get signal.
Kindle handles this offline gap perfectly. Some other apps I’ve tried require you to manually open the book while online to 'push' your progress. That’s not real sync; that’s a manual backup. Always check reviews for comments on offline sync behavior.

Aldiko is a classic, but the older Aldiko Book Reader (not Aldiko Next) doesn't do cloud sync in the free version. You'd need the paid upgrade for that. So, scratch that one off your list if sync is a must-have for no cost.

I can confidently say that yes, there are free apps that sync across devices seamlessly. My top pick is 'Libby' by OverDrive, which links to your local library card and syncs your reading progress, bookmarks, and notes across smartphones, tablets, and even some e-readers. The UI is clean, and the borrowing system feels like having a digital library in your pocket.
Another great option is 'Google Play Books,' which not only syncs your progress but also lets you upload personal EPUB or PDF files. The downside is the limited free catalog, but the cross-device functionality is flawless. For those who prefer open-source, 'FBReader' with its cloud sync plugin works wonders, though it requires a bit of setup. These apps have transformed my reading habits, letting me switch from my phone during commutes to my tablet at home without missing a beat.
