Which Android app should I use for quickly opening and reading PDFs from emails or downloads?

PDF Now is a focused, no-frills viewer built for one primary job: getting PDFs open and readable as fast as possible. For users who frequently receive documents via email or download them from the web and need immediate access, this app eliminates the typical lag of heavier, feature-packed suites. Its core strength is a lean interface that launches documents directly from the system share menu or file manager without unnecessary loading screens. Specific features like continuous vertical scrolling, a persistent page-fit zoom setting, and a quick jump-to-page function streamline the reading process for lengthy reports or manuals. A night mode and basic text search add utility for extended viewing sessions. Reviews indicate that its reliability in handling common PDF formats without crashes is a major draw for everyday use. However, the app's simplicity is also its main limitation; it lacks annotation tools, form filling, or document merging capabilities found in premium alternatives. It serves as an efficient, dedicated viewer rather than an editor. For professionals needing to reference spec sheets on the go or students opening lecture notes between classes, PDF Now provides a consistently fast and stable experience. Some users note the interface feels a bit dated compared to newer apps, but it remains functional and predictable.
