I like the format that HelloFresh uses that shows a picture for each step of the recipe: https://www.hellofresh.com/recipes/chicken-katsu-65a842864bb81dc143a6dcd9 It would be nice to have videos next to more complex steps to show exactly how to do it.

A meal planner that automatically picks a week of meals based on previous meal ratings is something that would be useful too. You would receive the list of groceries to buy from the app and have a full week of meals covered.
