A simple problem I routinely have is that I buy groceries without planning meals. This often means I end up with a lot of waste by simply forgetting some foods need to be used or they'll spoil and I end up throwing them out, costing me a small fortune over time. I realise it's quite lazy to turn to technology to try and deal with this but are there any apps that can 'remind' me that my eggs need to be used within the next day or so if I bang the data from my shopping trolley in?
