Natura has unveiled the Interface smart ring, which lets users summon AI agents and execute tasks with a finger press, while also tracking health metrics such as sleep and heart rate. Preorders begin next month, with shipping expected in December or January, and a planned $9 monthly subscription after a free trial period.
The AI and hardware startup Natura has unveiled the Interface ring, a wearable device with a launch price of $99, designed to give users quick access to AI agents without having to hold a phone. With a finger press, users can request that a task be carried out, record an idea or meeting, or control connected devices.
Natura was founded by Carlo Edoardo Ferraris, the founder of device-accessories company Rolling Square. The company had previously introduced the HumanPods earbuds, designed for interacting with AI agents, but it turned to the ring as a device that can be worn for extended periods, including while sleeping and showering, according to the company’s description.
Multiple agents from a single interface
At launch, Interface is expected to connect with a range of AI agents and applications, including Meta’s Muse, Instinct, Grok Bot, Claude, and ChatGPT. Users can designate the agent responsible for a task, such as using Claude to write code, Instinct to book an appointment or restaurant, and Grok Bot for another task.
Responses are delivered through connected earbuds, iPhone’s Live Activity feature, or the NatureOS app. Natura also says the ring can control devices, including computers, enabling commands such as starting workout tracking, displaying the day’s schedule, reordering a household product, turning off the television, setting an alarm, or sending meeting notes to a colleague.
Health tracking and a later subscription
Alongside its AI functions, the ring monitors heart rate, resting heart rate, heart-rate variability, sleep stages, daily movement, step count, and skin temperature over time. The company estimates battery life at between six and 12 days per charge, depending on usage, while a full charge takes 100 minutes.
Natura plans to open preorders next month, with shipping expected in December or January. The ring will initially be offered for $99, but the company plans to raise the price in the future. After an initial free period lasting three to six months, it plans to charge a $9 monthly subscription.
What changes in practice?
Interface attempts to combine two relatively separate markets: health-focused rings represented by companies such as Oura, Ultrahuman, and RingConn, and devices focused on interacting with AI agents, such as Pebble and Vocci. Natura’s proposed value is not limited to adding health sensors; it lies in making the ring a continuous access point to multiple services and enabling tasks that would normally require a screen or phone.
However, the practical experience remains tied to the availability of compatible agents and applications, as well as the accuracy of voice commands and their integration with other devices. The advertised price also does not reflect the ongoing cost after the free period ends, since use will become tied to a monthly subscription if Natura implements its current plan.
