What's New in CrossX

2.8

October 2, 2026

RSS feeds now refresh with pull-to-refresh. Large EPUBs are optimized before upload for faster transfers. Add wallpapers to an existing .sleep folder, import your own EPUB and PDF files, and open queue items in the built-in reader. Plus clearer error messages and bug fixes.

Im on X3

and everything works seamlessly. I have RSS feeds, is there a way to check all as read if i only want to sync the last few articles, versus syncing them all? Thank you for this app!!

Everything works but Wallpaper on X3

Everything works really well. It looks great. The sending of books is easy and connecting to the E reader is seamless. The only issue is that is not updated for the X3.

So far I love this app! I’m
looking for long form articles to really put it through its paces. Very slick to connect the x4 to my iPhone!
