Lithium Pro is a license add on app that unlocks Pro features for Lithium EPUB Reader.
Lithium Pro is made for readers who already use Lithium EPUB Reader and want extra options inside the same reading app. It does not open EPUB files by itself, so the free Lithium app must be installed first. After that, Lithium Pro works as a paid license that activates added tools in the main reader. For users checking the Lithium Pro APK, the key point is that this app supports the existing Lithium reading setup rather than replacing it.
Pro license for Lithium EPUB Reader
Lithium Pro unlocks Pro features inside Lithium EPUB Reader by FaultException. You need to keep both apps installed on your Android phone, because Lithium Pro acts as the license and the free Lithium app remains the reader. This setup is useful for users who already manage EPUB books in Lithium and want to add paid functions without changing reading apps.
Reading data sync through Google Drive
Lithium Pro lets you sync reading position, highlights, notes, bookmarks, and other reading data across devices through Google Drive. If you read on more than one Android device, this helps you continue from the same place without manually checking where you stopped. It also keeps your annotations available when you move between devices using the same reading workflow.
Custom reading themes
Lithium Pro adds more control over how pages look during reading. You can adjust the page background, text color, and link color to match your preferred reading environment. This is helpful during long reading sessions, especially when standard light, night, or sepia styles do not fit your eyes or room lighting.
More highlight colors
You can use more highlight colors after activating Lithium Pro. This makes it easier to separate ideas, quotes, study points, or sections that need later review. Instead of marking every passage in the same color, you can give your notes clearer meaning while staying inside the Lithium EPUB Reader interface.
Works with Lithium’s core reader tools
Lithium Pro builds on the main Lithium EPUB Reader experience rather than changing how the reader works. The main app still handles automatic book detection, EPUB library management, page and scrolling reading modes, night mode, sepia themes, highlights, and notes. As a result, users who download Lithium Pro can keep their familiar library while adding license based features.
Lithium Pro is not a separate EPUB reader. Before installing it, users should understand that it depends on Lithium EPUB Reader, which is the main app used to open and read EPUB files. If the free reader is not installed, Lithium Pro will not provide a standalone bookshelf or reading screen.
For best results, install Lithium EPUB Reader first, then install Lithium Pro and leave it on the device. Removing the license app may stop Pro features from staying active inside the reader. This is an important detail for users comparing Lithium Pro download options, because the value of the app comes from unlocking features in another installed app.
Users who care about book layout should also note that Lithium EPUB Reader is designed for EPUB files and aims to preserve the book’s formatting while keeping reading controls simple. Lithium Pro adds extra options around syncing, colors, and annotation organization, but it does not turn the app into a general document viewer for every file type.
