holycalc

We came up with Holycalc because, as a hairstylist, I needed a quick way to calculate the cost of hair coloring materials. Usually, we’d do it by remembering the price per gram and multiplying it by the quantity used—super time-consuming! I figured others might deal with the same hassle. It’s already helped some people in other professions, but I’m curious—do you think this could be useful outside of hairdressing, or is it just my specific use case? Would love to hear your thoughts! 😊
