The original neapolitan style pizza recipe
This is in my opinion from where you should start if you never made a pizza dough, set values on the app as following:

Dough balls number: how many pizzas you want to make, for example enter 3 if you're going to make 3 pizzas.
Dough balls weight: 250g
Hydration: 58-60%
Salt: 50g/L, it means 50g per liter of water in the recipe. The same is for Oil/lard/butter.
Oil/lard/butter: 0g/L
Room temperature: take a look at your thermostat
Rising time: 8h
Fridge rising time: 0h, the dough will stay at room temperature all the time, you'll never put it in the refrigerator.
