It's worse than just having to trust their metrics. Last time I looked, you can't access your own realtime heart rate no matter what - it was only available to 'registered partners' or some shit. When I was looking, their partners page had a demo video of a crowd watching a football match, and had that overlaid with the heart rates of the fans. So basically, next level sentiment monitoring and advertising capabilities.

So actually, Fitbit is in the business of collecting high resolution fitness data which they onsell to 'partners', and they've managed to convince the public to PAY to have this data collected about them in exchange for really coarse aggregated statistics which are an order of magnitude less useful than what Fitbit extracts from the raw data and keeps for themselves.

Fitbit's marketing strategy is the work of evil geniuses.
