Do I need to have extensive knowledge about ice cream production to use the application?

No, but you should know the basics to at least adjust the flavors you make with pastes :) If you're lacking ice cream knowledge, don't worry—our innovative Kangaroo Method training, based on the app, will teach you how to design ice cream flavors (sorbets, vegan, keto, gelato, etc.) in just one day. Seriously. :)
