QuiverBooks supports EPUB, MOBI, AZW (Kindle), PDF, and CBZ (comic books). All DRM-free content.
Tap the import button in the Library tab. You can import from Files, iCloud Drive, Dropbox, or any connected cloud storage. You can also use the iOS Share Sheet from other apps or drag-and-drop on macOS.
No. QuiverBooks supports DRM-free files only. Books purchased from stores with DRM (like most Kindle purchases) cannot be opened. Consider purchasing from DRM-free retailers.
Books are stored locally on your device in the app's sandboxed storage. They are included in your device backups.
Reading progress is calculated based on your position in the book. For EPUB/MOBI files, this is based on chapter and scroll position. For PDFs, it's based on page number. If progress seems off after an import, try opening the book and navigating to where you left off.
