I want to create a product cost calculator app which contains a list of ingredients, number of servings, unit size and contains a formula that calculates the cost per unit.
We currently use a spreadsheet with too many sheets to calculate the cost of our products. What I need to make is an app that will facilitate the process and have users add new entries and when they add new entries, I want to the app to do automatic calculations like excel google sheet does. The thing is that the app is not reading from the formulas which are provided in the google sheets. So does the app use a different language or certain codings that I have to learn in order to create automated calculations?
