It would be really cool to know how prepared you would be in the event of something happening. I have seen this on another app, a free app however I do not want to enter my stockpile into another app that takes a lot of time.
To add to this - I would want to be able to set my own level of what "prepared" is. I might buy more canned corn if my quantity minimum was set to 10, but perhaps my family goal is a 3 month supply - so I could enter those goal numbers. Then I could change it and increase our goal to 6 months.
