I've been reading about what the rest of the world seems to be calling "quantified self". In essence, it is tracking of personal data like activity, usually with the goal of data-driven decision making. Or to take a less abstract common example: counting the number of steps you take each day to motivate yourself to take more. I wish it'd been given a less annoying woolly name but this one seems to have stuck.
There are a couple of interesting devices available that track sleep, activity and overall health. Probably best known are the FitBit and the jazzed-up armband pedometers like the Jawbone UP and the Nike Fuelband. Unfortunately all existing devices seem to integrate with cloud services somehow, rather than giving the user direct access to their data. Apart from the usual privacy concerns, this means that it is hard to do your own data crunching or create a dashboard that contains data from multiple sources.
Has anybody found any devices that don't integrate with the cloud and just provide raw data access?
