What I found was not very satisfying on a few different levels:
- Access to your own data is only available if you a premium subscriber - that is, you pay an additional $49.99/year (after you've already bought the device).
- Even when starting a seven day free trial period to download the data, it is only available with nothing greater than daily granularity. A bit of poking around on the Google Group for fitbit developers indicates that only a "select few" developers will have access to sub-daily data.
- The data is presented poorly - there are three separate sections in the CSV: body, activities, sleep. All are keyed on date. Why not one section with more columns?
- The data has odd inconsistencies:
- If you request dates for which you hadn't used your fitbit, you will get information that isn't real - i.e., no minutes of activity rather than null values
- For data where you have limited entries - weight, blood pressure, resting heart rate, etc., fitbit does different things: weight is repeated, blood pressure is 0/0 instead of NA, resting heart rate is 0 instead of NA.
I'm still down on the whole environment that is out there now. That said, I signed up for a MeetUp group (for DC) that is associated with the Quantified Self.
After I've had a chance to go through the data, I will share my insights (if any).
