FreshClock- feedback on my app

Hi everyone! I'm Lee, a solo maker. I've been building FreshClock, an iPhone app that shows what to eat before it spoils and counts the money you save.

Building it made me curious how other people handle this. Do you track what's in your fridge at all, or just go by look and smell? Has anything actually helped you throw away less food?

Here's what I ended up with: you snap a grocery receipt, or tap the foods you bought, and typical expiry dates fill in for the fridge, freezer and pantry. Everything is sorted by what needs eating first, and if you freeze something, its date moves.

FreshClock launches here on Product Hunt tomorrow, November 15. I'd love your feedback: what would make an app like this useful in your kitchen, and what would make you stop using it after a week?
