Natura Unveils $99 Interface Smart Ring With AI Agents and Health Tracking

Natura has introduced Interface, a $99 smart ring that gives users quick access to AI agents while also tracking health. The company says the wearable lets users trigger tasks, capture thoughts and manage daily actions without taking out a phone.

The new device sits at the centre of Natura’s pitch that AI needs a more natural, always-available interface. According to the official Interface product page, the ring is built to work with AI agents and apps while also tracking heart rate, heart rate variability, sleep, activity and other wellness metrics.

A smart ring built for the AI agent era

Natura says Interface is meant to let users interact with AI the way they would ask another person for help. A finger press can trigger an AI request, letting the ring handle tasks without requiring the user to unlock a phone or open an app.

At launch, the company plans to connect the ring to a range of AI services, including Meta’s Muse, Instinct, Grok Bot, Claude, and ChatGPT. Users can also choose which agent handles a task, for example, asking one service to write code and another to manage a reservation or another everyday request.

Responses can be delivered through connected headphones, an iPhone Live Activity or the company’s NatureOS app. Natura is positioning the device as an always-on layer for AI assistance rather than a screen-based gadget that competes with a smartphone.

Health tracking is part of the pitch

Alongside its AI features, Interface includes a health and activity tracking system similar to what buyers would expect from other smart rings. Natura says the ring tracks heart rate, resting heart rate, heart rate variability, sleep stages, daily movement, step count and skin temperature over time.

The company says the ring lasts 6 to 12 days on a charge, depending on usage, and takes about 100 minutes to recharge fully. Natura is using AI access and health monitoring as its main differentiator in a market where many rings focus mainly on wellness data.

Natura sees the ring as a constant interface

Carlo Edoardo Ferraris founded the startup and previously built consumer hardware through Rolling Square. After working in hardware accessories, Ferraris concluded that AI’s rapid progress created a need for a new type of interface that stays with the user throughout the day.

Natura’s earlier product, HumanPods, explored that idea through AI-enabled earbuds. The company later decided a ring made more sense for continuous access because it can stay on longer, including while sleeping, exercising, or showering.

That constant availability is central to the company’s vision. Natura argues that people increasingly want immediate access to AI tools for tasks such as checking a schedule, starting a workout, reordering household items, controlling connected devices, recording meetings or sending notes to a colleague.

Low launch price, subscription to follow

Natura plans to open preorders next month, with shipments expected in December or January. The ring will launch at $99, a price the company says is meant to lower the barrier to entry and expand adoption before raising it later.

After an initial free period lasting three to six months, Natura plans to charge a $9 monthly subscription. The company says manufacturing costs are comparable to devices such as the Oura Ring and Samsung Galaxy Ring because of similar internal components. Still, it is choosing a lower introductory price to attract early users.

Ferraris believes the broader opportunity goes beyond wellness tracking. He sees AI agents gradually taking over more tasks currently done through apps and computer screens, from filling out forms and messaging to finding files and drafting presentations. In that vision, Interface is designed to serve as a small, always-available gateway to those agents while also covering the health-tracking functions consumers already expect from a smart ring.
