But if you’re on the fence about whether to go out and buy the latest model, a new study may save you money.
A study published Tuesday in the Journal of the America Medical Association has found that apps available on smartphones are just as accurate as wearable devices dedicated solely to fitness.
Researchers at the University of Pennsylvania’s school of medicine asked healthy adult participants to walk on a treadmill while loaded up with devices of all kinds. Fourteen subjects walked for 500 and 1,500 steps during a total of 56 sessions.
The devices worn included the popular Flex FitBit, the Digi-Walker Sw-200 pedometer by Yamax, iPhone 5s running apps such as FitBit and Health Mate and Samsung Galaxy S4s running the Moves app, according to the study.
Then, the data was gathered and compared to the known number of steps actually taken.
An accessible fitness tool
The data collected by smartphone were only slightly different from the observed step counts, according to the statement. The data from the devices was in some cases closer to reality but in others differed much more than the worst smartphone app.
Senior author Mitesh S. Patel suggested that these findings are relevant to public health, since a majority of people own a smartphone, not a fitness device.
"Our findings suggest that smartphone apps could prove to be a more widely accessible and affordable way of tracking health behaviors," he said in the statement.
