This IDC study contains our projections for the number of applications that will be written to smart wearable devices through 2019. Forecast projections are split by applications primarily targeting consumer use cases and those targeting enterprise use cases. At this time, we have not drawn a distinction between "standalone" application builds and those functionally dependent on "host" devices (usually smartphones).
"It has been clear since well before it was launched that the Apple Watch, with the WatchKit SDK, is poised to set a tone for the broader market," said John Jackson, research vice president, Mobile and Connected Platforms at IDC. "Competitors have the reasonable hope that any success Apple enjoys will propagate across products and ecosystems," he continued. "Though the consumer proposition is somewhat muddled, for enterprises the time is now. We believe enterprises will find numerous points of intercept for existing and new workflows and wearable solutions that deliver potentially transformative productivity and competitive benefits."
