This app does not provide a lot of solid information. For all of the trim data for example and APQ,EPQ it does not provide any food data, where some other computer programs will provide a estimated trim for a particular type of food and offer a library of ingredients that have trim information. Why even offer a trim option on the app if there is no data for it? Anyone can weight the product then cut the trim and weight again to get the info. The library of ingredients offered food economics is a joke, mostly processed foods. If you are attending a culinary college you will learn culinary math while attending such as I did. This will help you throughout your career and sometime other areas such as spotting a bad culinary app. I thought this would be a fun app being familiar with other apps by wolfram but I was wrong. Spend your money elsewhere.
