What's the best Android app for opening PDFs quickly without bloat?

PDF Reader Lite is a straightforward viewer designed for users who prioritize speed and simplicity over complex editing suites. The app launches quickly and opens documents almost instantly, even with larger file sizes, which is ideal for checking reports, viewing manuals, or reading e-books on the go. Its primary interface is uncluttered, focusing on core navigation like scrolling, zooming, and jumping to specific pages. Specific features include a text search function to find terms within a document and a night mode that reduces eye strain during prolonged reading sessions. For real-world use, it's well-suited for students pulling up lecture notes between classes or professionals referencing a contract during a commute. However, reviews indicate the app is less capable for users needing to annotate or significantly modify files, as its editing tools are basic. Some users also report that the free version displays occasional banner ads, though they are generally unobtrusive. The developer, MsGAMEuT, has maintained consistent updates focused on stability rather than feature bloat, which aligns with the app's lightweight philosophy. Overall, it serves its intended purpose reliably, providing a frictionless experience for fundamental PDF consumption without demanding significant storage space or system resources.
