Smartwatches are an emerging market. Sales have reached 5.1 million units between 2013 and 2014. A hackathon event was held to develop apps for the Apple Watch and Android Wear platforms. The Apple Watch launched in April 2015 starting at $349 and has limitations for developers due to restricted APIs. While smartwatches are not fully ready for the mainstream, their success will depend largely on how well the Apple Watch sells and whether it drives further adoption. Smartwatch competitors need the Apple Watch to succeed in order for the market to grow.
