Protowire

Rather than something you do at the end, Protowire aims to integrate interaction and animation into the design process without having to change your designs to suit the software.

Integrated into Sketch No need to export to a separate prototyping application - review the prototype instantly in Sketch or on a device.

UI Animations Just by moving layers around you can have overlays appear and disappear.

Screen Transitions Quickly create the flow of your app by linking up artboards from layers or hotspots.

Responsive Design? Use Sketch’s resizing constraints and responsive artboard groups to make prototypes that work on any screen size.
