Year 2012, almost all of us have smart phones. There are many companies out there that are trying to find solutions for health/activity tracking. I even worked for one of them, Fitbit. And including Fitbit, I can't find one company/product that can nail this problem. I've used Fitbit Ultra for a long time. I love so many things about it, I designed so many things for it. I hate the fact that it's so easy to loose, I can't sync without a computer. Then I started using the well-designed FuelBand. It's not accurate for me and can't get too many details from it. So I started using RunKeeper to track my walks/runs. But then realized, I just don't want to manually start/stop an activity on my phone every time I go out. Pls someone enlighten me.
