How do you managed budget and food?
As for food I can't really help there. I ended up writing my own app to manage/track expiration dates for what I have but that's barely the tip of the ice-burg. I hope to integrate with my recipe app (Paprika) to work on meal-planning and picking recipes I like while trying to use up the stuff that will go bad first.
The app is, I think, a natural evolution for the YNABer who got the discipline and now doesn't need to track every single dollar all the time.
we look at statements from our various accounts, enter into a data tab, then group expenses into categories: house (elec, water, cable, etc), food, vehicles (gas, tolls, oil, loan, etc) fun (spotify, netflix, etc).
as the saying goes, you cant manage what you dont measure.
