Paper
Paper is a digital sketching and creative notebook application designed for iPhone and iPad that allows users to capture ideas visually through drawing, painting, diagramming, and collage creation. It provides a clean, distraction-free interface with responsive drawing tools that replicate the feel of sketching on paper while allowing users to work entirely within a digital workspace. Its drawing engine includes a collection of finely tuned brushes and tools that make it easy to sketch concepts, create illustrations, annotate photos, or build visual notes directly on the screen. The interface relies heavily on natural gestures rather than complex menus, allowing users to stay focused on their creative flow while navigating pages and editing content. Users can also combine multiple photos within a single canvas and manipulate them by cutting, moving, or layering them alongside drawings and handwritten elements to create visual compositions or mood boards.
