What it does
PDF Viewer supports PDF reading, search, annotations, forms, signatures, and sharing on iPad, iPhone, Mac, and Android. Its interface includes an annotation list and style inspector.
Use the annotation list to revisit a proposal's comments and the Inspector to keep their styles consistent. For page order on iOS, open the grid editor, enter edit mode, hold and drag pages, then confirm with the checkmark and choose a save option. Unconfirmed changes are lost when leaving that editor. Pro adds document merging and annotation replies/reviews; some controls remain platform-specific, such as iOS page copying and Android freeform annotation rotation. The app is separate from Nutrient's SDK products.
