Study: Smartphones Just As Good As Fitness Trackers For Counting Steps

jfruh writes While dedicated fitness trackers that you wear around your wrist have any number of functions, many people are focused on a single metric: counting steps, which serves as a proxy for determining how active you are. But a recent study from the University of Pennsylvania showed that if that's mainly what you want out of a fitness tracker, then you almost certainly have a device in your pocket that can do the same thing as well if not better: your smartphone.

      I think they're all quite usable. In this space utility is not dependent on accuracy, for most people, because for most people it really doesn't matter if you get an extremely accurate step count. What matters is that you get a reasonable estimate of your activity level, as compared with you activity level measured on other days.

      Fitbit tries to estimate calories burned from your walking, and if that were at all accurate, it could arguably be important to get an accurate step count. But it's not, because people are too different.

      For most of a year I performed very detailed tracking of my caloric intake vs expenditure, including the use of a Fitbit step tracker and a cycling power meter, and plotted those against my weight gain/loss. What I found, once I had determined by base metabolic rate, was that estimating caloric expenditure with the power meter is highly accurate, but Fitbit's estimate of my caloric expenditure due to walking consistently overreported by about 30%.

      That's not because Fitbit is doing anything wrong; their pedometers are quite accurate and I'm sure they're using reasonable models for estimating energy use based on the walker's weight and height. The fact that the overreporting rate was so consistent even though my body weight changed by almost 15% supports this. A friend who did the same experiment for a while found that for him the Fitbit-reported caloric expenditure only slightly overreported. He and I are different; perhaps his walking style is significantly less efficient than mine, or perhaps it's something in the composition of our diets (the human body is an imperfect heat engine; different sorts of foods are converted with varying efficiencies, and even the combinations matter).

      Then I tried using my phone to measure my steps. It reported far fewer steps than my Fitbit did every day, which concerned me, so I did some tests. I walked some measured courses with both and counted my steps. The Fitbit was darned near perfect, being off by only a step or two in thousands -- and it's entirely possible that those errors were mine, not the device's, since I was counting mentally rather than using a counting device. The phone, was bad... but in a consistent way. In fact, I found that, for me, applying Fitbit's formula (using their web site) but my phone's step counts actually provided a much better estimate of caloric expenditure, when calibrated against weight change.

      If you're actually trying to convert steps to calories, I think inter-person variability is a bigger factor than device accuracy, and if you're anal enough to actually try to calibrate the system, your calibration for the former will easily take care of the latter -- as long as you consistently use the same device.

      However most people don't, and won't ever, do the controlled experimentation and analysis to calibrate themselves. So what most people really use a pedometer for is to (a) track relative physical activity level over time and (b) set and work towards goals of increasing activity. If what matters is relative activity, then an inaccurate but reasonably consistent device is just as good as a perfectly-accurate device.

      And you probably already have a phone, which is a reasonably-consistent pedometer. If you already have a Nike Fuelband, that works, too.

    Yes, FitBit's advantages include the fact that it follows you everywhere since it's more easily worn anywhere, including the shower nowadays for some of the newer models.

    I got a FitBit as a gift for a good friend of mine. She was appalled by how it asks for permission to send very private info, and was really hesitant about starting to use it. (And I thought *I* was the one always warning people about society being apathetic about the insidious encroachment of privacy by software!) I did some digging and found articles on the web nothing that "Ira Hunt, the agency's chief tech officer, had this to say about fitness bands: 'What's really most intriguing is that you can be 100% guaranteed to be identified by simply your gait - how you walk.'"

    Also, apparently FitBit asks for permission to access your Contacts info on the iPhone, purportedly just so it can contact all your friends who own FitBits and tell them how excited you are to have gotten one.

    Would it be true that, with a smartphone app rather than a purpose-built device, you'd have more control over the privacy settings and what the fitness program does with its data? At least, presumably, there would be a choice of apps and you could choose one that is less invasive of privacy. I don't know because I use a Linux(Maemo)-based phone and don't have access to the wonderful world of Android/iPhone. Any comments in this regard would be appreciated.

    Epilogue: My friend started to set up her FitBit but got scared enough about per privacy that she decided to return it.
