Paper prototypes are great ways to get your ideas quick on to something tangible. I make paper prototypes for my interfaces and ideas quite often. But when I want to take it a little bit more upscale and make slightly more hi-fi versions, I'm just clueless.
I want things to be interactive, and I want them to be really easy. I've used inVision and didn't quite like it. I like Adobe XD and Sketch, but I want something less sophisticated than that. Is there anything between paper prototypes and Adobe CC or Sketch?
I want something that's (1) easy and quick to draw up something (2) has good collaborative features. I've searched and read many different blogs, but I cannot judge without really using them. But then I cannot use all the available tools.
What do I do?
