hey guys as reading threads in PPI forum section i get more confusing as time goes by.. i am doing cpi with android or ios mobile apps. and i only thought cpi/ppi was to install apps from mobile phone.. but if not wrong i can see cpi/ppi is not only occuring with mobile phone but with internet exe? rar? files... can please someone explain? is there 2 types of cpi/ppi? mobile app and exe/rar?? and how do they work? thank you guys in advance!
