For instance, if you add photo upload to your app, people will complain if it doesn’t support multi-photo upload, varying sizes, and client side photo filters.
The bar is set very high. It’s taken me a whole year to build a website + app combo in my spare time that has all the expected bells and whistles on top of the app’s regular functionality (social login, site tours, optimistic states, skeleton loading, push notifications, global type agnostic search, etc). MVP took two months but every time I showed to people, the reaction was always “why isn’t it autosuggesting content? Where is the explore page? Why can’t I login with my Facebook, why aren’t you saving drafts while I create posts in case my computer crashes, etc).
It really is a ton of effort to turn a simple idea into reality
