LiquidText – PDF and Document Reader for Annotating, Researching, Highlighting and More offers gesture based reading and annotating of documents. This app allows you to focus the relevant pages of a PDF and organize your notes. You can even share your annotations.
This PDF reader app is designed to not only help you read PDFs, but organize and highlight relevant information contained within it. Once you start using it, you will wonder how you read PDFs on an iPad without it.
This is the first public version of the app to be released. The developer describes features of the app as follows:
• Read and interact with text in a flexible environment
• Compatible with PDF, Word, and PowerPoint documents and web pages
• Import from Dropbox, iCloud Drive, Box, email, and more
• Import content from webpage or send to LiquidText directly from Safari
• Workspace area for writing notes and pulling out excerpts
• Organize and group excerpts and notes
• Tap comments and excerpts to find original source
• Pinch document to compare different sections
• Collapse text to see annotated parts side-by-side
• Collapse text to view search term(s) side-by-side
• Scroll to navigate through pages
• Scrollbar shows where highlights, comments, excerpts, and search results are located
• Highlight text, images, comments, excerpts, and notes
• Add margin notes/comments to text, images, notes, and excerpts
• Comment on two or more selections simultaneously
• Export file as notes only, highlights only, notes and highlights, or entire document with annotations
• Export as LiquidText file, PDF, or RTF (supported by most word processors)
