In the U.S., 71% of those with smartphones own either an Android device or an iPhone. But when it comes to smartphone apps, iPhones and Android smartphones are even more dominant: 83% of app downloaders, that is, those who downloaded an app in the past 30 days, use iPhone or Android smartphones, according to new data released today by Nielsen. 

The media research firm estimates 44% of all US mobile subscribers now have smartphones. Among those who purchased a new mobile phone in the last three months, 56% chose smartphones. Android remains the leading smartphone operating system while Apple is the top smartphone manufacturer.
