In the space of two weeks, I've gone from not tracking my steps, calories, or activities to using four different devices that do so. I'm all in! Over the coming weeks, I'm going to be sharing more about how each device works in real life.
It's been a fascinating journey so far, and I'm anxious to get into the write-ups. I'll detail what it's like with each unit, then do an overall comparison at the end. But before I start on that, I feel that an introductory piece is in order.
The devices I'm using are:
Until recently, I'd heard the most about Fitbit. It seemed like everyone I knew in the tech world had one. To me, it seemed a waste of time. Seemingly geared toward counting steps, how was the Fitbit going to measure my main activities, which aren't step-based?
Working from home, I don't walk much. I don't run. I inline skate several times per week. How's that going to count without steps? On weekends, I often take short bike rides, where I'm again not stepping. I also stand-up paddleboard on a regular basis, where I'm definitely not stepping.
I thought it would be fun to put them all to the test.
That's what I've been doing for the past two weeks, pitting them against each other. On my left wrist, I'm wearing the Jawbone Up and the Nike FuelBand. On my upper left arm is the BodyMedia Fit (worn much higher than shown in the picture above). On my waist, the Fitbit One. They're my constant companions, even during sleep -- something that all but the Nike band will record and track in different ways.
If you're wondering which is best, stay tuned. But the short answer is...it depends.
It depends on the activities you do, what you want out of the associated apps, and, most important, how motivated they make you feel.
As I've often said about other tech products, there's no "wrong" choice. What works for you, works for you. If any of these devices help you get in shape and stay in shape, that's great. But there are definitely factors to consider, and I'll be covering those.
I will say that the early conclusion is that these bands are far less about how accurately they track exactly the calories you burn and much more about how they help you understand how active you've been relatively, from day to day. None of them is perfect, but any of them give you a good sense if you've been active or not versus your usual routine.
By the way, I'm not alone in my journey. Blogger Mark Krynsky coincidentally started the same testing as me, at the same time. We're now linked up together in the apps that allow this, and we're sharing thoughts on Twitter with each other and to the world. You can read his progress at Lifestream Blog. You can catch either of us sharing real-time experiences through Twitter. He's @krynsky on Twitter, and I'm @dannysullivan.
As for my own formal reviews, they'll start shortly, beginning with the Nike FuelBand, to be posted in the next day or so. As I review each, I'll update this page with a link to the review, as well as to the overall conclusion at the end. So bookmark this page and come back to read more.
