Hello, I have a general question for a react/react-native application. I am trying to get inputs from two different users on different devices, get the average of those two numbers, and then display the average on both of their screens. For best practice, how should I take those numbers from the user and get the average of both? Will I need to set a SQL database where the numbers are sent to, and then extracted from there? Thank you for the help, I just want to clarify how this kind of operation can be done.
