Smartphones are maligned for many things, but they might actually be helping improve the health of at least some users.According to new research from mobile analytics firm Flurry, now part of Oath, health and fitness app usage in the US has seen a sharp uptick over the past few years, growing by 330% between 2014 and 2017.These users are loading up their apps with a relatively high level of frequency. Flurry’s survey, conducted in August 2017, found that three-quarters of the health and fitness app users opened their apps at least twice per week. And more than one-quarter of respondents were at the very high end of usage, opening their app 10 times or more on a weekly basis.
