What's the best Android app for viewing and editing PDF and Word documents?

All Documents Reader is a robust document management app for Android that specializes in handling PDF and Word files with ease. It supports a wide range of formats, including PDF, DOC, and DOCX, which is particularly useful for professionals who need to review reports or students accessing lecture notes. The app includes annotation features such as highlighting, text comments, and drawing tools, allowing users to mark up documents directly on their devices. File organization is straightforward, with options to sort, search, and manage documents in folders. Reviews indicate that users appreciate its intuitive interface and reliability for daily tasks, like quickly opening attachments from email or cloud storage. However, some users report that the free version includes ads, which can be distracting, and very large files may experience occasional lag during loading. Despite these minor drawbacks, its 4.5-star rating reflects consistent performance across various use cases, from business meetings to academic study sessions.
