FiftyThree has released Paper, a new sketching and drawing app for the iPad. Focused on a providing a minimalist design, Paper acts as a simple notebook or journal effectively turning the entire iPad screen into a freeform drawing canvas with no additional buttons, controls or other distractions. The app instead relies heavily on a gesture-based control interface: users open and close journals and journal pages with pinch gestures, flip pages by swiping in from the bezel at the sides and access the drawing tools by swiping up from the bottom; users can “Rewind” (undo) by rotating with two fingers in a counter-clockwise direction while other one-finger gestures are used simply to draw on the page with the currently selected tool. The free app includes an eraser and single fountain pen drawing tool with 9 colours; additional tools are available via in-app purchase for $2 each or $8 for the full set of four. Paper is available from the App Store as a free download.
