The Icons8 team rolls out a global update for Lunacy, a native Windows app that opens, edits, and stores .sketch files. In short, it’s long-awaited Sketch for Windows. It helps design teams working on different operating systems and improves the transition from design to development. It's a beta version. And it’s completely free.
This is still in the early stages but I like what I see so far! As a product manager constantly working with designers, I can now open design files on PC for quick screen views, exports, etc. If that's your primary need this will be perfect!! If you are looking for a full featured Sketch replacement, it's not there quite yet.
Some personal opinions: A bit laggy. Also you can not lock something horizontally/ vertically by holding SHIFT. Some expected keyboard shortcuts doesn't exist (like ctlr+L to lock). Zoom-in & out speed could be a bit faster.
Sometime ago I just dreamed about such software, now it's real. Thanks guys, you're awesome!
finally I don't need a Mac to work with our designers
