Technology does help me to be more healthy. At least that's what I believe.
For the last month, I've been wearing Mi (Fitness) Band. It's a bracelet that keeps track you movement. It records the number of steps you have done at a particular time of the day. It can also record the number of hours you are sleeping. But, I am mainly focus on the number of steps (and the associated kilo meters I have walked).
I can synchronize the data with my iPhone. Here's an example of the result.
I can set a goal in terms of the number of steps per day. I set it at 8000 steps. Usually, I couldn't make it. Ha ha ha. I usually go from my car to my office, which is probably only 500 meters from the parking spot. That's not enough to achieve 8000 steps. Sometimes, I purposely park my car further so I have to force myself to walk more.
I also use Nike+ to track myself when I walk. But, Nike+ requires GPS and that sucks my battery really fast. So, I use Nike+ when I know that I can charge my cellphone right away after walking.
Stay healthy. Technology does bring good things to humanity.
