In my head, you would open your app, and "add canned tomatoes " and you would have stickers designed for only canned tomatoes. So from your app you could add 5, and put them away.
When it came time to use things, you would scan them like at a check out, and it would let the app know to let you know you are almost out.
But then it would become an issue of having stickers to use. I WOULD HATE to program each thing to its own label. I wohld use basics like, frozen meat, canned veggie, canned fruit, but that isn’t helpful much either if you need canned peas and only have carrots.
