Some questions about Fiori sizing

Hi,

Could you answer few questions about sizing, please?

1.      When we calculate the results, we get the information about required resources. What is the purpose of the “SAP Mobile Applications Fiori”? Are they mobile applications that work with Fiori (integrated with SMP), or something else?

2.      When we size Fiori apps and enter users data, there are only predefined apps available. And we should develop our own applications.  In this case which row should we use to enter the data, “APPROV-ALL” or maybe the other one?

3.      What data contains the “Integrator” column in this table?

Thanks in advance.
