I have a mobile app recommendation project, so I need data set which has user-app matrix-rate. Actually, I want to know what rate does a specific user submit for a specific application. in other words, "user-app matrix-rate" is a 2-D matrix, rows are users, columns are applications and cell(i,j) is rate of user i submit for application j.

In addition, It's good for me to know "user-app matrix-install" where "user-app matrix-install" is a 2-D matrix, rows are users, columns are applications and cell(i,j) is 1 if user i installed application j, otherwise cell(i,j) is 0

thanks for your help
