Lawyer and Mac enthusiast David Sparks describes it as being 'engineered around the idea of reviewing long PDF documents better.' It looks at books filled with post-it notes and string-covered bulletin boards and laughs. A traditional sign-and-form-fill annotation app this is not - LiquidText is built for projects, novels, research papers, and dusty libraries. I've rewritten this intro to LiquidText about five times now, largely because the multitouch annotation app has this slippery way of defying description. PDF Viewer can even rearrange, delete, or insert blank pages within a PDF, though it doesn't have some of the more advanced combination features (like merging multiple PDFs or adding existing PDF pages into a document). For instance, if you're looking at a document, you'll be shown the tools for sharing, zooming, and browsing through annotations tap the annotation button, and the app brings you into Annotation mode, with its various tools - still simplified into easy-to-understand icons. Taking a page from Apple's own iWork suite, the app provides a series of nested views depending on which feature you're using. It is a perfect in-between for users who need a bit more than what the iOS Markup tool provides, but don't need the power of apps like PDF Expert or LiquidText.Ī PDF app's interface can frequently appear daunting to the average user, thanks in part to the sheer number of annotation options developers try to shove inside of them, but PDF Viewer smartly simplifies this process.

PDF Viewer has a clean, simplistic interface and powerful annotation tools.
