alt Hacker NewsThe "what should we eat" problem was a big source of tension in our household since the arrival of our first child. Too much time-consuming, too much planning effort. What changed our life (and I really mean it) is the app https://jow.com: it suggests you a list of meals for the week suited to your family and equipment, and it creates a shopping list for your preferred delivery provider. I only have good things to say about it and could go on for hours.
We're actually in a unique situation where the planning+buying isn't the hard part, but the deciding is. We're within walking distance of a super-cheap grocery store and I'm able to cook a wide variety of dishes - many of which I can make quickly. The hard part is my wife doesn't do well with open-ended questions like "what would you like to eat"? Seeing a discrete list of things I can make and her just picking/submitting the options would solve the problem.
Though that only holds while we have free time. If we have a kid, then I can see a great amount of value in that app.
