The technical answer is that most official storefront apps support sync: Kindle, Kobo, Google Play Books, Apple Books, Nook. They all use their own cloud infrastructure to track your account, your library, and your reading progress. The real difference comes down to speed, reliability, and whether they support sideloaded content. Kindle and Google Play Books are the winners for letting you add your own files and still get sync benefits.

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 academic or technical PDFs, I don't rely on general e-reader apps for sync. Zotero with the Zotfile plugin and a cloud service is my workflow. I sync the PDFs themselves through Zotero's cloud, and then use an app like PDF Expert or Xodo that can open files from cloud storage and has its own robust annotation syncing. This two-layer approach—reference management plus a dedicated PDF reader—is overkill for novels, but for research where my margin notes and highlights are critical, it's the only method that's never let me down across a phone, tablet, and multiple computers.

Can we talk about battery life? It's related, I swear. Some apps are vampires in the background, constantly pinging for sync updates and murdering your phone battery. In my experience, Audible and Apple Books are fairly optimized. The worst offender I've used was a now-defunct smaller app. Good multi-device syncing should be efficient. If an app is keeping your phone awake to maintain sync, that's a poor implementation. I judge a platform not just by if it syncs, but by how gracefully it does it without impacting the rest of my device's performance.

Been using Kindles for over a decade, and honestly, the sync is so seamless I only notice when it fails—which is rare. The whole 'Whispersync' thing just works in the background. Finish a chapter on my phone during my commute, pick up the Oasis that evening, and it's right there, usually within a paragraph. It even syncs my notes and highlights almost instantly.
What I appreciate is that it's not just about the furthest page read. It remembers your precise position, which matters in dense non-fiction or technical manuals where you might flip back a few pages. The only glitch I've ever hit was with some sideloaded PDFs; for those, the sync can be hit or miss. But for anything bought from Amazon, it's like having a single, persistent bookmark that floats between all your devices without any effort on my part.
It feels less like a 'feature' and more like the expected baseline now, which is why it's so frustrating when other platforms can't get it right.

I've been using ebook libraries for years, and syncing across devices is a game-changer for readers like me. Most major platforms like Kindle, Kobo, and Google Play Books handle this seamlessly. Kindle, for instance, saves your progress, bookmarks, and notes in the cloud, so you can pick up right where you left off on any device. I switch between my phone, tablet, and e-reader constantly, and it's a relief not to lose my place. Some libraries even sync highlights across devices, which is perfect for students or avid note-takers. The only hiccup I've noticed is with DRM-protected books from certain publishers, but overall, modern ebook libraries have this feature down pat.

once you sign in with your Bookshop account, your purchased e-books sync automatically across devices. Your bookmarks, highlights, and last-read positions are stored in the cloud, allowing you to pick up where you left off on any device. This feature ensures a seamless reading experience between phone, tablet, and desktop.
