About Lithium Pro
Lithium Pro is a paid license app for the Lithium EPUB Reader.
FaultException built Lithium Pro for readers who want sync and deeper display control without changing the simple EPUB reading experience. It unlocks Pro tools inside Lithium EPUB Reader, so the free reader must remain installed on the same Android device. Before choosing a Lithium Pro APK, it helps to know what the license adds:
Activates Pro features inside Lithium EPUB Reader after installation. Syncs reading progress, highlights, notes, and bookmarks through Google Drive. Adds custom themes with adjustable background, text, and link colors. Provides extra highlight colors for study notes and saved passages. Keeps Lithium’s clean EPUB reading layout and familiar controls.Lithium Pro works as an upgrade license, not as a separate EPUB reader. Its main role is to activate paid features inside Lithium EPUB Reader, so users need the free reader installed first and should keep both apps on the same device. After activation, the reading experience stays centered in Lithium EPUB Reader rather than moving to a new interface.
This setup is useful for readers who already like Lithium’s simple layout and do not want a different bookshelf or reading screen. Lithium Pro adds tools around the existing reader, including sync, custom themes, and more highlight choices. The limitation is clear: opening the license app alone will not give users a standalone library, so the best approach is to treat it as a small companion app that unlocks extra options.
Google Drive sync helps keep reading data available across Android devices. With Lithium Pro, users can sync reading position, highlights, notes, bookmarks, and other reading details through a Google Drive account. This is practical for anyone who reads on a phone during travel and later continues on a tablet at home.
The feature focuses on reading data rather than replacing a full book backup system. EPUB files themselves are not currently backed up or synced, so users still need to place the same book files on each device. Once the books are available, synced progress and annotations make it easier to continue from the right place without manually checking the last page or copying notes between devices.
Custom themes give more control over how EPUB books look during long reading sessions. Lithium Pro adds options for adjusting background, text, and link colors, which helps users build a comfortable screen for daytime reading, low-light reading, or personal visual preference. The base reader already includes night and sepia themes, and Pro customization adds more flexibility on top of those choices.
The custom theme controls appear inside Lithium EPUB Reader after the license is active. Users can find them from display settings by opening the three-dot menu under “Theme,” but the important part is the result: a reading screen that can feel softer, clearer, or more personal depending on the book and lighting. This is especially helpful for long novels, textbooks, or any EPUB with dense paragraphs.
Extra highlight colors make annotations easier to sort at a glance. Lithium Pro expands the highlight tools in Lithium EPUB Reader, giving users more color choices when marking quotes, study points, reminders, or important passages. For students and careful readers, this can make a long EPUB feel more organized without adding a complex note system.
A simple use case is separating character details, key arguments, and follow-up questions with different colors. The reader’s notes and bookmarks still stay within the familiar Lithium workflow, while the added color range gives more meaning to each mark. This feature is small, but it can make a real difference when returning to a book after several days.
Lithium EPUB Reader remains the main reading app, and Lithium Pro does not change its basic strengths. The core reader can automatically detect EPUB books, preserve formatting well, and offer page mode or scrolling mode for different reading styles. Users who prefer book-like page turns can stay with page mode, while scrolling mode may feel better for short sessions on a phone.
The app also supports notes, bookmarks, and built-in night or sepia themes, which makes the Pro upgrade feel like an extension rather than a replacement. Some users have reported file permission issues on newer Android versions, so keeping Android permissions in order may be necessary if books do not appear as expected. Since the latest known Lithium EPUB Reader update was on 27 Jan 2025 and no separate Pro changelog was provided, users should check version details before updating.
The following points reflect how Lithium Pro works as a license for an already familiar EPUB reader. Its strengths come from sync and customization, while its limits mostly relate to setup and file handling.
Pros Useful upgrade without changing the main reader experience. Google Drive sync supports multi-device reading habits. Custom themes improve comfort during long sessions. Extra highlight colors help organize annotations. Works with Lithium’s clean, ad-free EPUB reader.Cons Requires the free Lithium EPUB Reader app. EPUB files are not synced or backed up. Some newer Android devices may face permission issues.You can download Lithium Pro latest version from APKPure to activate Pro features inside Lithium EPUB Reader. Since the license app itself is very small and the provided package size is listed as no meaningful app data, the download should usually finish quickly on a stable connection. The main thing to prepare is the free Lithium EPUB Reader, which must already be installed or kept on the same device.
After downloading and installing the Lithium Pro APK, open Lithium EPUB Reader to use the upgraded tools. Pro options appear inside the reader, not in a separate bookshelf or reading screen. Before starting sync, make sure the same EPUB files are available on each device, because Google Drive sync covers reading position, notes, highlights, and bookmarks rather than the book files themselves.
