Natura's $99 Interface ring takes agent requests and hands the answers to a phone or headphones

Someone in the shower notices the shampoo has run out, presses the ring and asks an agent to reorder it. Natura uses that scene as one of its own examples ^[9]. The reply has three places to go: connected headphones, an iPhone Live Activity or the NatureOS app ^[3]. Few people wear earbuds in the shower, so the confirmation sits on the phone until they dry off.

Natura's founder, Carlo Edoardo Ferraris, previously started the accessories maker Rolling Square ^[10]. He pitches the ring well beyond shampoo. "Ultimately, the main interface between users and technology is going to be the ring," he said ^[18]. What ships is narrower. The ring takes a spoken request at the press of a finger and passes it to an agent such as Claude, ChatGPT, Meta's Muse, Instinct or Grokbot ^[1][2].

The company's working assumption is that people want an agent within reach at every hour. "You can go shower with it; you can sleep with it. You never take it off," Ferraris said ^[8]. Natura is betting users will behave that way. What they actually do with it is unmeasured: the ring has not shipped, so there is no retention or usage data ^[4].

Natura's examples fall into two groups. Starting workout tracking mid-run, reordering from the shower and turning off the TV while falling asleep are moments when the phone is often out of reach ^[9]. Asking for the day's schedule on waking and sending meeting notes to a coworker are moments when it is usually nearby ^[9]. In the second group the ring saves the few seconds it takes to pick up a phone.

The best case for separate hardware is routing. A wearer can name the agent for each job, Claude to write code and Instinct to book a reservation in Natura's example ^[5]. I think this matters more than the ring shape. A device tied to no single agent company can send each task to whichever agent the user prefers.

Over two years, most of what an owner pays goes to the subscription. Counting the free period, the total is $261 to $288, of which $99 is the ring ^[17]. If the agent habit never forms, the buyer keeps a health ring that tracks heart rate, HRV, sleep stages, steps and skin temperature ^[6]. Oura, Ultrahuman and RingConn already sell health-first rings in that category ^[13].

Ferraris was plain about the first buyers. "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," he said ^[19]. He also forecast that "within a year, more or less, most people will have a personal agent" ^[20].

For a team deciding whether to pilot it, a 2x2 does the sorting. One axis asks whether the phone is within reach when the request is made. The other asks whether the answer can be heard or can wait, or has to be read on a screen straight away. Out-of-reach requests with answers that can wait are where the ring beats the phone. In-reach requests that must be read belong to the phone. In the other two boxes the ring saves seconds at most. A week's log of one person's agent requests, sorted into those boxes, shows whether the device is worth $108 a year for that person ^[15].
