Reminds me of the chicken feed app I saw about 40 years ago, before the internet It would find the best price for protein, carbohydrates etc in chicken feed looking at raw products like bone meal and maize with current prices. Remarkable actually, I wonder what happened to it? Anyone else remember any apps before the internet?
