Natura Puts AI Agents on a $99 Smart Ring With $9 Monthly Fee

Natura will sell a $99 AI-enabled smart ring called Interface, with a $9 monthly subscription after a free period of three to six months. Preorders open next month, with shipping slated for December or January.

The ring, from a company founded by Carlo Edoardo Ferraris, doubles as a health tracker and a controller for AI agents from Meta, Anthropic, and OpenAI. A press of the finger routes prompts to assistants including Claude, ChatGPT, Grok Bot, Instinct, and Meta's Muse.

What does the ring actually do?

Interface tracks heart rate, resting heart rate, heart rate variability, sleep stages, daily movement, step count, and skin temperature over time. The device accepts voice prompts and dispatches replies through paired headphones, an iPhone Live Activity, or Natura's NatureOS app, the company said.

The ring records meetings, retrieves files, fills in forms, drafts messages, and toggles household devices on or off. Users assign tasks to specific agents — Claude for code, for instance, or Instinct to book a restaurant.

Who built it, and why a ring?

Natura was founded by Ferraris, an entrepreneur who built tech accessories maker Rolling Square before turning to AI interfaces and wearable computing as foundation models moved into daily life.

Before Interface, Natura shipped HumanPods, AI-enabled earbuds designed to talk to AI agents. Ferraris said the form factor taught his team the limits of ear-worn hardware.

"Over time, we evolved to an understanding where you really want to have access to your agents 24/7," Ferraris told TechCrunch. "You don't want to have even one hour of your day where you cannot access them. And the form factor of the ring is perfect for this because it's basically an extension of you. You can go shower with it; you can sleep with it. You never take it off."

How is it priced?

Natura priced Interface at $99, below the flagship rings from Oura and Samsung, to widen adoption among buyers testing voice-first hardware they have not yet tried. A $9 monthly fee follows the free trial window.

The company says Interface uses components similar to those in the Oura Ring and Samsung Galaxy Ring. Manufacturing costs sit at comparable levels, but Natura wants the lower sticker price to seed demand before raising it later.

A full charge lasts six to 12 days, depending on usage. A full recharge takes 100 minutes.

Where does it sit in the smart-ring field?

The smart-ring category splits in two: health-first hardware from Oura, Ultrahuman, and RingConn, plus AI-first devices from newcomers including Pebble and Vocci. Natura pitches Interface as the first device to combine both at a consumer price.

"This ring that we're about to launch is significantly different compared to any other ring out there today because we were able to combine not only the highest quality health tracking with the rest of the components that allow for agent communication and meeting recordings and external memory," Ferraris said. "We were also able to do that with an incredibly long battery life, which is vital for a product like this, and in a size that is very, very small. The product itself is, from a hardware perspective, very different from anything else that's out there."

What does Natura want to become?

Ferraris frames the ring as a first step toward voice-driven computing, where screens and keyboards yield most everyday tasks to personal AI agents running in the cloud.

"Ultimately, the main interface between users and technology is going to be the ring," Ferraris said. "So it's not going to be immediate because even today, not everybody has a personal agent, but I think everybody is bound to have one. So in this first phase, we expect it's going to be for the people that already have a personal agent, which is mostly people in tech. But eventually, I think within a year, more or less, most people will have a personal agent."

If Ferraris is right about voice overtaking screens for daily work, a $99 ring plus a $9 monthly fee is now the price of admission to agent-first computing. If he is wrong, Interface joins a long list of smart-ring hopefuls chasing a category that still has not found a daily-use hook with consumers beyond sleep and step counts.
