FitStar Labs, Inc. was a San Francisco based consumer fitness company that built FitStar Personal Trainer and FitStar Yoga, adaptive video workout apps that adjusted each session to the user's feedback and fitness level. Backed by GV (Google Ventures) and Trinity Ventures, FitStar was acquired by Fitbit on March 5, 2015 for $17.8 million and folded into the Fitbit Coach product line. The company is DEFUNCT: the fitstar.com domain no longer serves web content (last archived live October 2017), the FitStar apps have been retired, and no developer portal, documentation, or public API surface survives. This profile is retained as a historical record in the API Evangelist network; there is nothing to enrich beyond identity and domain posture.
FitStar is profiled on the APIs.io network. Tagged areas include Company, Defunct, Acquired, Fitness, and Health and Wellness.
Regulatory Posture applies to this provider. Its tags matched the
Health regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/fitstar: open an issue to ask a question, or submit a pull request to add artifacts.
