After wearing my Fitbit bracelet I am still learning about the interface and feedback information.
My favorite feature is the feedback on exactly how much activity you had that day. No need to deceive yourself whether you worked out enough to eat more. Below is the Very Active Mins, Sleep, "Badge" for 10,000 steps, and Calories In vs Out.
Very Active Mins only includes VERY ACTIVE minutes. A casual Sunday walk won't qualify as active minutes which I think is good. To many people think they are exercising, but their heart rate has not increased.
Fitbit is a real motivator to know how much I've exercised every day, not just on my "work out days."
A Jeweler's evaluation of the clasp on Fitbit:
The clasp on the Fitbit is not great. As a jewelry maker, I'd give it a below average rating. It is very hard to close with one hand by yourself when it is new. After a year of wear it is much easier to put on, but the bracelet has opened and fallen off by accident. I think the designers wanted it to have a clean appearance, but I would have preferred something more secure and easier to use for the lifetime of the fitness band.
The wrist band on Fitbit is attractive with clean lines. That is great as far as that goes, but as solid rubber it gets sweaty or irritated underneath. I which it were a more breathable mesh or fabric.
RESPONSE TO MY PREVIOUS POST
To clear up any misunderstanding regarding my enthusiasm for this bracelet:
The FitBit presents a very clean and minimalist aesthetic. It is not as "interesting" as most jewelry, ....but I am absolutely excited to anticipate the future of this beginning, in affordable, bio-monitoring jewelry.
Jewelry has a new role, and a new dimension of value beyond materials or decoration. This jewelry empowers fitness in a whole new way.
The function of jewelry as identity takes on a new role with fitness. Wearing a FitBit, or other bio-monitor jewelry, means that the wearer is identified as a fitness enthusiast. While wearing my Fitbit, it has sparked a number of conversations, as we identify each other as part of an elite groups trading stories of fitness.
Yes, I do consider it affordable as an investment in your health. A visit to the drugstore can easily cost $100. on medicine. With this bracelet monitoring your activity level and the subsequent motivation for reaching 10,000 steps a day a Fitbit wearer could reduce the need for some medications (doctor approved, of course.)
I highly recommend investing in a new you with a Fitbit (or any other activity tracker.)
Imagine a future where your doctor can determine a prescription of lifestyle or activity to your Fitbit dashboard. The doctor determines the program and you can then work to achieve possibly lifesaving results at any time -- all monitored online by both you and your doctor!
Update July 2015:
My Fitbit has lasted 19 months even though I wear it every day. When the electronic component finally wears out I am definitely getting the new model with the heart rate monitor. (My current version does not adequately capture effort expended during biking or floor exercises.)
