Sketch (mac app)

Is this a useful tool for web development? I thought about purchasing it and learning/using it, but I don’t know how well it fits in with ruby on rails and other stuff.
I am a weak programmer, and even weaker designer (I prefer black and white text).



It's a tool for UI/UX designers, but only you can decide whether it's
useful for your work.

There's a free trial version - why not test-drive that and decide?

Yes, I tried it. But it expired after a couple of days.
