Hm, I never understood doing app interfaces with Photoshop — it was never a good solution for that — I always used AI, or even Indesign — vector based software.

Well Sketch had a nice headstart but the restriction to Mac is a nogo and I knew Adobe would come out with something — like the Adobe Experience Designer (which is in Beta for Windows). And I love it — and the best thing — they could watch Sketch grow up and jump right to the whre they implement the useful stuff and without the clutter that Sketches Interface already has.

So give it a try.
