Which Android app should I use for quickly jumping between pages and sections in large PDF documents?

PDF Jumper is an Android application tailored for users who need efficient navigation within PDF files, particularly those dealing with large documents such as academic textbooks, technical manuals, or business reports. The app excels in providing quick access to specific pages and sections through features like a built-in bookmark system, which allows users to save and revisit key points instantly. Additionally, it supports table of contents extraction for structured documents, enabling one-click jumps to chapters or headings. For real-world scenarios, such as a student studying for exams or a professional referencing a lengthy guide, these tools reduce time spent scrolling and enhance productivity. Reviews indicate that the interface is straightforward, with minimal loading times for most files, though some users report that the free version includes ads that can occasionally interrupt the reading flow. The app also includes a page search function for text-based navigation, but it may struggle with scanned PDFs that lack OCR capabilities. Overall, PDF Jumper balances functionality with simplicity, making it a reliable choice for organized PDF reading on mobile devices.
