Tech With A Purpose

I’ve been on this kick for sometime now to get some kind of fitness tracker that’s independent, a bit, from my mobile. Not that services like Sports Tracker, etc aren’t good. It’s just that I don’t want to always have my mobile on me on order for them to make their value apparent. Instead, I want the tech to work with my mobile, be independent from a specific platform focus, and blend into the background when I don’t care to know it’s using my activities. That’s not too much to ask given the pace of tech now right?
