Tonal

Tonal is a connected fitness company founded in 2013 by Aly Orady and headquartered in San Francisco, best known for its wall-mounted smart home gym that uses digital weight (electromagnetic resistance) and AI-powered coaching to deliver personalized strength training. The Tonal 2 hardware pairs with a subscription membership offering adaptive weight adjustment, science-backed workout programs, live and on-demand classes, and progress tracking. Tonal publishes no first-party developer API, but its Shopify-hosted storefront exposes an agent-commerce surface: an llms.txt, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, and an MCP endpoint for agent-driven shopping.

Tonal is profiled on the APIs.io network. Tagged areas include Company, Health Wellness, Fitness, Strength Training, and Connected Fitness.

Tonal’s developer surface includes engineering blog, support, pricing, and 14 more developer resources.

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.

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/. This rating is computed from github.com/api-evangelist/tonal: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
