I'm a big fan of apps that use their own dedicated cloud, like BookFusion or PocketBook, over those that piggyback on Dropbox. The integrated clouds are optimized for the task. With Dropbox sync, I've had issues where the sync file gets locked or conflicts if I'm too quick switching devices.
A service built for reading data seems to handle the rapid, small updates of page positions better than a general file-syncing service. The experience feels more cohesive and less like a hacky add-on.

Remember the old 'Send to Kindle' trick? You can email a PDF to your Kindle's email address, and Amazon converts it and adds it to your Kindle library. From there, Whispersync tracks your progress across the Kindle app on Android and any Kindle device. The conversion can mess up complex layouts, but for text-based PDFs, it's a magical way to get rock-solid Amazon-grade sync.
You're then using the Kindle app as your reader, which is fine but not amazing for PDFs. However, the sync is arguably the most reliable in the world. It's a weird workaround, but for people already invested in the Kindle ecosystem, it's a seamless way to bring personal PDFs into that synced world. A classic case of thinking outside the app.

My advice is to stop using PDFs for long-form reading if you can help it. Convert them to EPUB using Calibre or a tool like 'Convertio' online. The reflowable text format is what sync features are built for. Once it's an EPUB, every major reader app will sync your progress flawlessly because it can track by word or paragraph, not by a static pixel location on a page. You'll also get adjustable fonts, margins, and spacing. I only use PDF readers for documents that must preserve their exact layout, like forms, comics, or academic papers with complex figures. For novels or text-heavy books, conversion is the real progress-sync hack.

It works so well I take it for granted now. I'll be reading a novel on my Kindle Paperwhite at home, then get to a doctor's appointment and pull out my phone. Two taps later, I'm in the same spot. The key is that all these devices are registered to my Amazon account. The progress isn't stored on the device; it's stored against my account in the cloud.
Each device just fetches the latest 'bookmark' when it opens the book. If you're offline when you stop reading, the device will usually hold that progress locally and send it to the cloud the next time it connects, updating the master record. It's elegantly simple and incredibly effective.

iBooks—the built-in Apple Books app—handles PDF progress sync via iCloud without any fuss. It's not the most powerful for annotation, but if simple reading and having your spot follow you from iPad to iPhone to Mac is the goal, it's free and just works.

I switched from the basic Kindle text-to-speech to Audible’s Whispersync for exactly this feature, and the difference is huge. My morning commute uses the app’s voice narration, and it picks up perfectly on my Kindle at lunch. The sync isn’t just about page numbers; it aligns with sentence fragments so you don’t lose your place mid-paragraph. I’ve noticed some older titles or sideloaded books can glitch, skipping a few sentences forward when you switch modes.
Honestly, the reliability depends entirely on the platform’s ecosystem. Apple Books handles it seamlessly across my devices, but I’ve had mixed results with Google Play Books on an Android tablet versus the web player. It’s one of those features that feels like magic when it works and makes you want to throw your phone when it doesn’t. My tip is to stick within one brand’s walled garden for the best results.
I still manually check the progress bar sometimes out of habit, a little paranoid from past bad experiences with other apps.

I rely heavily on apps that sync progress seamlessly. Kindle is my go-to because it updates my page position almost instantly whether I switch from my phone to tablet or e-reader. Google Play Books also does a decent job, though sometimes there’s a slight lag. I’ve noticed apps like Libby (for library books) sync well too, but only if you use the same library account. The key is sticking to one ecosystem—Amazon, Google, or Apple—because cross-platform sync can be hit or miss. Offline reading sometimes delays updates, but reopening the app usually fixes it.

syncing progress is crucial for a seamless experience. Most book apps like 'Goodreads' or 'Kindle' handle this automatically if you're logged into the same account. For 'Kindle', your progress syncs via Whispernet, so just ensure your devices are connected to Wi-Fi or data. Some apps, like 'Libby', require manual sync—just tap the sync button in the app settings after finishing a chapter.
If you're using a smaller app, check if it supports cloud backups. For instance, 'Moon+ Reader' lets you link Google Drive or Dropbox to save reading data. Always double-check the app’s settings for 'Auto-sync' or 'Cloud Backup' options. A pro tip: if switching between iOS and Android, stick to cross-platform apps like 'Google Play Books' to avoid compatibility issues. Lastly, clear your cache occasionally—sometimes syncing hiccups happen due to outdated temp files.
