What happened
Natura announced Interface, a $99 smart ring that connects with agents including Meta's Muse, Claude and ChatGPT, tracks health metrics, and is set for preorders next month.
Why it matters
The ring aims to combine AI agent control with health tracking — a pairing Natura says sets it apart from rivals that focus on one or the other.
What to watch
Shipping is slated for December or January, and after an initial three- to six-month free period, Natura plans to charge a $9 monthly subscription fee.
WHO IT HITSConsumers who already use personal AI agents — mostly people in tech, as Natura's founder puts it — are the first target, along with health-tracking wearable buyers comparing it to devices like the Oura Ring.

Natura is not new to AI hardware. Its first product was HumanPods, a pair of AI-enabled earbuds designed to let users interact with agents. The company says it moved to a ring because voice technology had advanced enough to support a form factor people never take off.
Founder Carlo Edoardo Ferraris, who previously founded tech accessories company Rolling Square, frames the ring as a bet that the main interface between people and technology will eventually be the ring itself. He expects adoption to start with people who already have a personal agent — mostly in tech — before broadening.
The ring enters a market already populated by health-focused players such as Oura, Ultrahuman, and RingConn, plus AI-focused rings from Pebble and Vocci. Natura says its manufacturing costs are comparable to the Oura Ring and Samsung Galaxy Ring because they use many of the same components, but it is pricing lower at first to reduce the barrier to entry.
