PDF Scanner App Documents Scan by SHTRO TOO positions itself as a mobile document digitization solution for iOS users seeking to convert physical papers into organized digital files. The application leverages the iPhone's camera to capture various document types while automatically enhancing readability and providing searchable text output. The core functionality revolves around intelligent document detection that automatically identifies paper edges and applies perspective correction. The optical character recognition system enables text extraction from scanned documents, allowing users to copy and repurpose content. Additional features include multiple export formats, cloud storage integration, and batch processing capabilities for handling multiple documents simultaneously. User experience centers on a minimalist interface with large capture buttons and intuitive editing tools. The scanning process involves three steps: capture, enhancement, and export. Real-world usage patterns show highest utility for digitizing receipts during business travel, capturing whiteboard notes in educational settings, and archiving important paperwork for home organization. The app performs best in well-lit environments where document edges are clearly visible. With no user reviews available at publication, the application's 4-star App Store rating suggests generally positive reception. The absence of detailed user feedback makes comprehensive evaluation challenging, though the rating indicates satisfactory performance for basic scanning needs without significant technical issues reported by the developer. The application demonstrates strongest performance in quick document capture and basic OCR tasks, though limitations appear in complex document handling and advanced editing features. It serves as a competent entry-level solution for occasional users rather than heavy-duty professional document management, with particular effectiveness for students digitizing lecture notes and professionals archiving travel receipts.
