WatchSim allows WatchKit developers to mirror their simulator windows onto an iPhone or iPad at actual size. The mirrored watch screen relays touch events back to the simulator allowing developers and designers to evaluate the user experience of their interfaces.
A simple outline bezel is included, but custom bezel designs can be uploaded to the app using iTunes file sharing.
WatchSim requires the free WatchSim Server (download from http://www.dannykeogan.com/apps/WatchSim.html) to function.
