This is an app available on the Apple app store that calculates pizza ratios based on time and temp, using known sourdough and baker's yeast growth curves. https://apps.apple.com/us/app/zacalc2/id896310723 zaCalc2

Yeast growth models were led by TXCraig1 on pizzamaking.com with many users contributing to the validation and improvment of the models. As a result of Craig sharing this information freely, this app will remain free on the app store forever, and is available open source here as well.
