Why do you think its not good practice?

I dont get why you said that. I don't see this so much as a marketing post.

Agreed that it is much more interesting than daily UI challenges which is purely visual. Trying to enter my email but the "Stay Tuned" button does nothing :(

is this a concept or on the app store?

We've been utilizing Sketch libraries to create wireframe components and flow diagrams. These documents are created within a large artboard as we pull in other artboard symbols of the actual screen designs and link them together. We annotate directly onto the large artboard when we need to clarify the transition or interactions happening. https://useflowkit.com/ We use this library to link screens together and its been super useful.
