Redesign Concept
When I was first discovering Pinterest I felt like it wasn't second nature to any user to navigate. It's more of trial and error to figure out the features of the app version. This is my take/redesign on Pinterest, and how I believe it can have a easier interface. Noticed on the main feed of Pinterest, there are different shapes of posts, I think if all the post boxes were uniform a user can have less time scrolling and more time discovering. That way you can cover more groung per scroll, also I think it looks cleaner. Also you can easily navigate with anchored home buttons, so you can jump screen to screen.
