Seventy percent of US consumers own a smartphone, while just 5.7 percent own a fitness-sensing wristband, according to a GlobalWebIndex survey of 7,500 US internet users conducted in the fourth quarter of 2014.

Although GlobalWebIndex labeled the category "smart wristband", in the survey question, the research company used Nike+ FuelBand, Jawbone Up, and Adidas miCoach as its only examples. Two percent more men than women said they owned a wristworn tracker and people between the ages of 25 and 34 were more likely to own these devices than other age groups.

When asked about smartwatches, which included Pebble, Sony Smartwatch, and Samsung Galaxy Gear, 5.4 percent of respondents said they owned one. This group had a wider margin between men and women -- four percent more men than women owned a smartwatch.

GlobalWebIndex also asked respondents about app use. Just over 13 percent of respondents said they used a sports app and 12 percent used a health and fitness app. Health and fitness apps were used less than apps for map use, social networks, photo taking, and news, but used more than apps for location-based dating and television.

Fewer respondents owned fitness trackers and smartwatches in the US than did worldwide. Based on results from a late 2014 survey of 90,000 adults across 32 countries, GlobalWebIndex found that 7 percent of consumers owned a wristworn fitness tracker and 9 percent owned a smartwatch. App usage was also higher globally. Both sports apps and health and fitness apps were used by 15 percent of respondents.
