Which Android app should I use for quickly opening and viewing PDFs without unnecessary features?

Fast PDF Reader & Viewer is a straightforward application designed for users who need reliable and speedy access to PDF documents on their Android devices. Its primary appeal lies in its focus on the core task of viewing, eliminating the clutter of advanced editing suites that can slow down performance. For someone who regularly receives reports, manuals, or forms via email and needs to open them instantly, this app handles the job efficiently. Key features include a text search function to find specific terms within a document, night mode for comfortable reading in low light, and a file manager to organize local and cloud-stored PDFs. The interface is generally clean, with a recent files list that facilitates quick access.

However, reviews indicate some variability in performance, with occasional mentions of stuttering on very large or complex PDF files. The app includes basic annotation tools like highlighting, but these are not as robust as those found in premium competitors. For a student needing to swiftly open lecture notes or a professional reviewing a contract on the go, the app delivers competent core functionality. Its free tier is supported by ads, which can be intrusive for some, but the trade-off is a capable viewer that loads documents promptly without demanding significant storage space or system resources.
