As my title suggests this was very famous and doing amazing work when it launched. In its begining days it offers lots of features but now they become money hungry. They used to give lots of features but now only some left and with limitations. Here is a list of good & bad things about this app.
Good=
Still gives data on using some apps| Spin & Win offer| Gives data on referring| Give data on surfing on some sites.
Bad=
Used to give data on downloading apps but not now| Their Spin & Win offer is doing some kind of trick, they only give lowest data value| App needs lots of permissions| App becomes buggy| Not work perfectly.
