Lightweight Android document viewer that indexes PDFs and Office files
Indexes and displays PDFs, Word, Excel, and PowerPoint files in a single searchable list with vertical and horizontal viewing modes. Liti PDF Reader, from LengKeng Lab, targets students, educators, and business professionals who need fast local document access. Core functions include automatic scanning, quick filename search, bookmarking via a favorites system, and basic file management. The app fits people who prefer an offline, battery-friendly reader that keeps documents on device storage.
Liti focuses on local document access and fast discovery
Liti scans internal and external storage and builds a single indexed list of PDFs and major Office formats, so documents are available offline without cloud sync. The scanner recognises DOC, DOCX, XLS, XLSX, PPT, PPTX and PDF files, and the list supports sorting by name, size, or modification date. This index-based approach keeps all files in one place for quick retrieval during study sessions or meetings.
The app organises and manages files for on-device workflows
File management combines renaming, deleting, sharing, and a favorites system to structure work-related documents. Quick search finds full or partial filenames, and sorting filters let you group recent reports or large datasets. Use the sharing action to hand documents to other apps or collaborators on the same device, and mark frequently used items for instant access during presentations or review rounds.
Interface design reduces onboarding friction and permission needs
Onboarding requires only standard file system permissions to scan and display documents; there are no cloud account steps. The viewing area supports vertical and horizontal scrolling modes so readers can choose a layout for long reports or slide decks. The app's lightweight architecture is designed to conserve battery life and storage, which suits mobile work on standard business hardware.
Performance, format support, and limits for professional use
Performance emphasises quick load times for large documents and smooth scrolling, which users cite as a strong point. The app opens and displays Office files as well as PDFs, but it does not provide advanced PDF text editing. That design keeps the tool focused on viewing and simple management rather than document authoring within the app.
A clear fit for mobile readers who need offline indexing and fast access
Liti is a suitable option for professionals and students who require rapid, offline viewing and simple document organisation on Android devices. It favours read-and-manage workflows over in-app editing, so choose it when you need a compact reader and indexed library; expect advertisements in the free distribution as the main trade-off for that simplicity.
