Sandijs Ruluks Quite interesting post. There are actually lots of tools to be honest. Lately i purchased Affinity Designer as i am a windows user and i wanted to use Sketch.
But not having Mac and also the trailers and function of Affinity Designer kind of attracted me. It seems like a promising tool. You can check it out.
Invisionapp is great. But i have noticed one thing, that most of the prototyping tools or software are supported in MAC e.g. principle,sketch etc. rather than windows.
Anyways quite interesting post.
