This is cool, but can I easily dump and analyze my own data? Hopefully there is some API to foster visualization applications or at least a way to dump it externally. Needing to rely on one or some assortment of predefined apps always makes me feel like it's not my data.

If you're on iOS, my understanding is Pebble will write to the Health app.

From there you can analyze the data. You can't export directly using the app, but you can view all records or find one of many apps that support HealthKit which may possibly export for you.
