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.
