Non user-hostile technology would happily solve this problem: you pull from the fridge what is about to finish or before throwing the empty container into the trash, put it in front of a mini camera mounted on the fridge, image (possibly also barcode) recognition would identify the product, then you say a magic word and it would be added it to your list directly on the phone, then software would calculate the best path to the shops having in stock the products in the list. Sadly, this would be hijacked by businesses in no time by making it dependent from some cloud services then selling your data to other advertisers or by pestering you with offers of similar competing products. As of today, I still prefer a pen and a piece of paper over any type of automation.
