The growing business of kids' smartwatches

Just over 30 million smartwatches were sold worldwide in 2015, according to research from Gartner, a figure that's expected to more than double in two years to reach 66.7 million in 2017. The symbolic 50-million mark is likely to be passed in 2016. The smartwatch market now includes a growing number of models aimed at children, with varying degrees of functionality and fun features. The main purpose of most models is to locate kids via GPS and send emergency messages to parents.

Linkoo Kids Launched by a French start-up and on sale for €129 (approx. $143), the Linkoo Kids functions as a watch, a mobile phone and a GPS. It has an SOS mode that can be activated at any time, directly calling a specific phone number chosen by parents or sending an SMS signaling the child's exact location. The watch also has an anti-theft sensor, sending parents an SMS with the child's location if the watch is forcibly removed from their wrist. The watch ships with a built-in SIM card and requires a monthly subscription (€7.90 or approx. $8.75) to use all of its functions (calls, SMS and unlimited GPS data).
