Natura introduces a $99 smart ring for AI agents and health tracking

Natura has introduced Interface, a $99 smart ring designed to put AI agents within reach with a finger press. It combines spoken requests with health tracking rather than choosing between them. Preorders are expected in November 2026, with shipping planned for December or January, according to TechCrunch’s October 8 report.

A request on the finger, a response elsewhere

Natura says its launch connections will include Meta’s Muse, Instinct, Grokbot, Claude and ChatGPT. Users will be able to name the service they want to handle a particular request. The ring is designed to reach an AI agent—software that can carry out tasks—or capture a thought.

Natura’s proposed uses include checking the day’s schedule, starting workout tracking and reordering shampoo. It also describes recording a meeting and asking an agent to send notes to a coworker. These are company use-case examples, not independently verified demonstrations of the ring completing those tasks.

Responses can arrive through connected headphones, an iPhone Live Activity or the NatureOS app. The ring supplies the shortcut for making the request; the connected headphones or software provide a way to receive the answer.

Interface follows HumanPods, Natura’s AI-enabled earbuds. Founder Carlo Edoardo Ferraris told TechCrunch that a ring people could wear while sleeping or showering better suited his ambition for continuous access to agents.

You don’t want to have even one hour of your day where you cannot access them.

Health tracking shares the hardware

Natura’s stated tracking features

• Heart rate, resting heart rate and heart rate variability.
• Sleep stages, daily movement and step count.
• Changes in skin temperature over time.

Natura claims six to 12 days of battery life, depending on usage, and 100 minutes for a full recharge. Those are company-supplied figures, not independent test results.

The introductory price is only the starting cost

The $99 price is intended to encourage adoption, rather than serve as a permanent price promise. Natura plans to raise it eventually, after getting devices into people’s hands and building demand. It has not specified a future price or date.

After an initial three- to six-month free period, Natura plans to charge $9 a month. Buyers would therefore face a recurring cost beyond the hardware purchase. The next step is opening preorders, followed by the planned December or January shipments.
