* Handle invalid input: if I say I bought my pork on 'lol' it tells me I have NaN days to eat it.<p>* I had to experimentally derive the purpose of the date field to mean "that's when it expires". No UI hint there.<p>* Why won't your app let me eat something that hasn't expired? Maybe I just want to eat my pork that will never go bad because I said it expires on lol.<p>* I can't figure out how I'd track things I already bought, as opposed to what I bought today. Does that even matter? I think it won't but that's based on my guess for what the date is.<p>Concept is cool, at least.<p>It would be nice if you could suggest & derive expiration dates -- if I buy "ground beef", maybe suggest "refrigerated ground beef", "frozen ground beef", ... and suggest an expiration date based on what the product is.<p>And it would be <i>killer</i> if you were able to suggest recipes based on what you have/what is expiring. I'd pay for that, no joke.
