Smartphone users in the UK downloaded over 860m applications in 2010, including 105m downloads of paid apps. Revenue from paid-for apps totalled £280m.
These are some of the findings of a new report from research2guidance, titled UK Smartphone App Market Overview.
The analyst believes there is still plenty of room for growth, noting that the majority of mobile users still have feature phones, and do not use apps as actively as smartphone users. In the years to come, it says, this potential will be explored and will drive up market growth. The research also reveals that young females show the highest dynamics of device adoption in 2010. At the current rate of growth, female smartphone adopters will catch up with their male counterparts within a year.
