Doubts about OSCalendar and OsProperty

Hello,
Before to buy this products, I would like to ask some question:

1.- OS Calendar is resposive?
2.- Os Property allows hide fields on the web but entering data into the backend? Also for the fields created by the user?
3.- With Os Calendar is possible to control the visit with date, name, phone of client interested in the property? Is it possible to check the visits then ?

Thanks in advance
