Initially, Qwikly will support Sketch designs and generate iOS apps. Since both of those technologies are Mac-only, Qwikly will initially only work on Mac machines. However, once we add support for non-Mac-only design tools (e.g. Illustrator / Photoshop) and output platforms (e.g. Android), we will be able to bring Qwikly to other platforms like Windows and Linux. The underlying technology we are using should make Qwikly portable to other platforms, but it will initially be for Mac.
