Millennial Fox

Millennial Fox, Inc. is a Los Angeles-based consumer company backed by Lightspeed Venture Partners that set out to bridge the gap between entertainment and fitness. Its flagship product, Tracks Battle Squad, was a socially gamified workout companion for iOS and watchOS that integrated with the Apple Health app to turn physical activity into points, badges, and accessories for a virtual 3D fox character. The app launched in 2017, was featured on Apple Music's Planet of the Apps, and has since been removed from the App Store; the company appears inactive and exposes no public API, developer portal, documentation, or well-known surface.

Millennial Fox is profiled on the APIs.io network. Tagged areas include Company, Fitness, Health, Consumer, and Mobile.
