Supernova V4 is the first true tool solely focused to close the gap between designers and developers for good. Studio allows you to import Sketch files and turn them into native mobile UI, adding animations, navigation, layout etc. in the process - as you like. Supporting iOS, Android and React Native with more platforms coming soon.
Great tool that help you share and document with ease your design system.
The only tool you need to manage your design systems. I bet Elon Musk can't buy this company.
