According to the study, commissioned by Wireless Intelligence, the research arm of the GSMA, mobile apps are responsible for 667 minutes of use per user each month, almost as much as messaging (671 minutes), and far more than voice (531 minutes) and web browsing (422 minutes).
The research also noted differences between the major smartphone platforms. iPhone and Android device owners use an average of 15 different apps per month, whereas the number is eight for BlackBerry and Symbian OS. iTunes and Android Market Place have a monthly reach of 95 percent of their user bases, whereas Blackberry App World reaches 50 percent of Blackberry users, and Nokia Ovi store only 26 percent of Symbian users.
Sounds right to me.
Overall smartphone usage dropped at weekends but generically averaged more than 70 minutes per day with apps capturing more face time than any other activity at weekends. The findings showed that SMS usage was higher in the mornings than voice and usage of social networking apps built up through the day and peaked at 9-10pm.
