Pro Multiple device support
Prototyping on Paper supports both Android and iOS.
Pro Based on sketched wireframes
Prototypes made on PoP are based on sketches made on paper or a whiteboard, which are later photographed or scanned and uploaded into the app. Once that's done, hotspots can then be added, which register tapping or several gestures.
Con Not well suited for complex prototypes
PoP is built to be a tool for quick prototyping, especially in participatory design sessions. For complex prototypes with a lot of screens it would require a large number of images to be used and this can make any project hard to maintain.
