The Problem
Everyone opens PDFs on their phone — contracts, tickets, textbooks, statements — yet most mobile readers are heavy, slow to launch, and buried in ads. A document viewer should get out of the way, not become a chore.
The Solution
Fast PDF opens files the moment you tap them. It renders large documents smoothly, remembers where you left off, and handles the everyday jobs people actually need: search inside a file, annotate, share, and convert to and from other formats — all in a clean, distraction-free reader.
Technology Used
- Platform: Native Android (Kotlin)
- Rendering: A tuned PDF engine for fast, low-memory display of large files
- Search & annotation: In-document text search, highlights, and notes
- Conversion: Import and export across common document formats
