IDC has new research into Smartphone shipments and predictions for 2018. 1.3 billion smartphones will ship this year representing an increase of 26.3% compared to 2013. However, this growth is set to decline to about 9.8% compound annual growth between 2014 and 2018. The respective Android and iOS market shares are expected to stay at about the same order of magnitude over this period.
If IDC are right, this means we will be entering a relatively stable period for mobile developers with no major differences in market share likely to cause developers to switch between platforms.
Generally speaking, if you are selling something then iOS will continue to be your most important platform as it’s a self-selecting group of users who have higher disposable income. If you are providing a service and need reach, then Android is your most important platform as it represents 82.3% of devices in use. However, my usual advice applies – survey your intended users and see what devices they own. Depending on your industry, you might be surprised.
