Calcolapizza is a free Android app developed by Domenico Majorana that allows you to calculate the exact amount of ingredients needed to make your pizza doughs quickly and easily. With this app, you can set the number of dough balls you want to make, their weight, the desired hydration, and all the other necessary values to create your custom pizza recipe. You can also save your recipe for future use or share it with your friends.

This app is an Android version of the official tool by the forum La Confraternita della Pizza, and all the credit goes to them. The app provides the original Neapolitan-style pizza recipe as a starting point for those who have never made pizza dough before. By setting the values as per the recipe, you can make your pizza dough with ease. The app is open source, and you can find the source code on the app's website.
