The latest report from Localytics suggests that BlackBerry usage is concentrated and higher during the workday, while iPhone app usage peaks around 9PM on weeknights. Localytics took this information from millions of phones in the US and Canada over 2 months.
The stats reveal much of what you would expect, including that iPhone owners use mobile apps more frequently on the weekend where usage is 40% higher than BlackBerry during the same time Monday through Friday. Mobile app usage for iPhone users peaks at 9PM EST during the week.
Blackberry mobile app usage is clearly higher throughout the workday and starts to peak at 7 pm EST, two hours earlier than the iPhone. There is also no statistically significant difference in the usage of BlackBerry apps on the weekend compared to Monday through Friday, unlike the iPhone.
