Natura's 'Interface' Ring Promises AI Ubiquity and Health Tracking for $99

The startup claims its new wearable combines high-quality health metrics with a hub for AI agents, but the lack of sensor validation leaves its medical utility in question.
Natura, a hardware and AI startup founded by Carlo Edoardo Ferraris, is entering the smart ring market with a device called Interface. Priced at $99, the ring is positioned as a tool for the era of AI agents, aiming to reduce screen time by allowing users to trigger tasks through voice and finger presses, as TechCrunch first reported.
**The AI Agent Hub** The primary value proposition of Interface is its role as a physical gateway to various AI agents. Ferraris, who previously founded the tech accessories firm Rolling Square, told TechCrunch that the ring is designed to be a constant extension of the user, allowing for 24/7 access to AI without a smartphone.
At launch, the ring will integrate with several AI agents and applications, including ChatGPT, Claude, Grok Bot, Instinct, and Meta’s Muse. Users can request tasks such as reordering shampoo, starting workout tracks, or setting alarms. TechCrunch reports that users can also record meetings and ask the AI to send notes to colleagues. Ferraris envisions the ring eventually replacing screen-based tasks like drafting presentations, filling out forms, and finding files.
Responses are delivered via the NatureOS app, iPhone Live Activity, or connected headphones. Users can assign specific agents to specific tasks, such as utilizing Claude for coding or Instinct for booking reservations.
**Health Tracking and Hardware** Natura claims Interface is also a robust health tracker, monitoring heart rate, resting heart rate, heart rate variability (HRV), skin temperature over time, daily movement, step count, and various sleep stages.
Natura claims the device lasts between six and 12 days on a single charge and requires 100 minutes for a full recharge. Ferraris told TechCrunch that the device is hardware-distinct due to its small size and the combination of health tracking with external memory and agent communication.
**Pricing and Market Strategy** Natura is launching at $99 to drive early adoption, though the company intends to raise the price in the future. Natura notes its manufacturing costs are comparable to the Samsung Galaxy Ring and Oura Ring because they share many of the same components.
Following an initial free period lasting three to six months, Natura plans to implement a $9 monthly subscription fee. Preorders are expected to open next month, with shipping scheduled for December or January.
**Opinion: Grace Delaney's Take** Natura is promising a Swiss Army knife of AI and health tracking for under a hundred bucks, but from an evidence-first perspective, there is a glaring omission: peer-reviewed sensor validation.
Ferraris claims the ring combines "highest quality health tracking" with AI capabilities, yet the company provides no clinical data or third-party validation to support these claims. In a market where Oura and Samsung have spent years refining their sensor arrays, Natura's assertion that they are using "many of the same components" to achieve comparable results is a bold claim that requires more than a press release. Until Natura provides transparent, validated data on the accuracy of its HRV and skin temperature sensors, the health tracking aspect of Interface remains speculative. Without that evidence, the device is less of a medical tool and more of a piece of overpriced jewelry with a voice assistant attached.
