The iterative design process plays an important role in ensuring the usability of a product when developing mobile apps. Herein we present Xketch, a sketch-based prototyping tool that can accelerate the iterative design process for designing apps. Designers can build a prototype by using simple strokes for creating UI components or interactive flows. That prototype can be immediately tested to collect user feedback. And it's effortless to transfer the design from lo-fi to hi-fi for different purposes of testing. Finally, it's easy to modify the design iteratively within a single tool. Xketch benefits app developers in designing apps quickly right on their tablet. Thus, app developers can focus on designing the user experience rather than building prototypes with various tools.
