Only app I've found that renders some audio epubs legibly and with sound. Updated 2024: I am using Lithium even more than before because I like to purchase ebooks direct from the authors (trying to lose that AMZ monopoly on my purchases) . My wishlist would be 1) to be able to read pdf books as well, 2) to repair/edit epub data like title and author (incorrect data isn't searchable or sortable otherwise). I wouldn't mind paying a small (very small) annual fee to help app development.

ALMOST the PERFECT epub reader app! I love this epub reader more than any other but my one issue is that there's no option to have both the book-wide page progress indicator bar AND a chapter-wide progress indicator bar (or a scroll bar that shows up when you tap the screen to bring up the UI). I want to be able to track both my book-wide progress and my chapter-wide progress because sometimes chapters are extremely long and it helps manage my time if I know the progress of both at a glance.

I used to be able to sync with Google drive, but now it says there is nothing there. other epub readers can even though I don't like using them as well as Lithium. I can't even find a folder on my tablet that Lithium will draw from. This quickly went from first to worst. The app used to connect to my google drive so that I could pull a book down and read it. Now it connects but nothing is shown. Other apps can find it, but this on now doesn't.

Hi, Sync does not Sync the books themselves. Or do you mean it says there's no notes or bookmarks?
