Technical point: apps that use a proprietary format and controlled ecosystem (like Kindle with AZW3/KFX) have an easier time with perfect sync because they control every variable. Apps that try to sync generic EPUBs across different rendering engines face a tougher challenge. That's why your mileage may vary with an app like Lithium or KOReader, even with cloud backup. The format and the reading engine need to be perfectly aligned on all devices for pixel-perfect positioning, which is hard in an open ecosystem.

For pure, no-strings-attached syncing of your personal EPUB/PDF collection, BookFusion is worth a serious look. It gives you cloud storage for your books, and the reading progress, highlights, and bookmarks sync instantly across their web, iOS, and Android apps. The free tier has a storage limit, but it's plenty for dozens of books. The experience feels modern and focused on readers who curate their own libraries, not just shop in a store. It filled the void left by the death of the original Google Play Books vision.

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.

The humble bookmark is part of sync! An app that syncs your last page but forgets your bookmarks is only doing half the job. I use bookmarks to flag passages I want to revisit or quote. Losing those between devices is as frustrating as losing my page.
My evaluation now includes adding a bookmark on my phone and checking for it on my tablet. You'd be surprised how many apps drop the ball here. It's a simple data point, but it reveals the depth of the syncing implementation.

Has anyone else noticed that good progress sync makes you read more? It removes the tiny barrier of finding your place. I find myself picking up my phone for just a minute because I know I won't lose my spot on the bigger screen. It's a psychological thing. The apps that nailed this—Kindle, Apple Books, Google Play Books—have fundamentally changed my reading habits. I finish books faster because reading happens in all the little moments, not just dedicated sittings.

I'm just here waiting to see if anyone mentions a magic app I haven't heard of. My Libby holds are all 8 weeks out, and I'm bored. Sync is cool, but content is king. Anyone have any hidden gem audiobook recommendations? I like weird horror and detailed historical fiction.

Trying to get your ebooks to follow you around is a legit struggle. I've had the best luck with Moon+ Reader Pro. You do need to set up a cloud folder (Dropbox, Google Drive, OneDrive) for your books, and the app reads directly from there. Once that's done, any reading progress gets saved back to that cloud file. It's a bit more manual setup than some, but you get incredible control over the reading experience itself. This method means your library and progress sync across any device that can access that cloud folder, not just Android. The customization options are worth the extra few minutes of configuration.

I have a love-hate relationship with it. Love the convenience, hate that it ties me to a specific ecosystem. I miss the days of just having an EPUB file I could throw into any reader app. Now, if I want perfect sync, I have to buy into a whole ecosystem. It's a trade-off. I use Kindle because it's frictionless, but I occasionally buy from Kobo just to feel like I'm not giving one company all my power. Their sync is good enough that it doesn't feel like a huge step down.

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.

OverDrive (the app, not just the website) does sync your position for library audiobooks. It's the older system that Libby replaced, but if your library still supports it, the functionality is there. The interface feels dated, but it gets the job done.
