Natura’s Interface is a smart ring designed to give you press-to-talk access to AI agents, while also tracking health metrics. The idea is simple: press and hold the ring’s button, speak, then release. Natura says a reply can arrive through a messaging app or optional in-ear audio. But the $99 price, subscription, battery life and delivery timing are launch claims that still need confirmation.
What does the Interface ring do?
Interface is a physical shortcut to voice interaction with AI agents. TechCrunch reports that a finger press can summon an agent, capture a thought or initiate a task. Natura’s product page describes the interaction as press, speak and release. The ring pairs with a phone and connects through Natura’s NatureOS, according to GamesBeat.

Natura says responses can arrive through WhatsApp, Telegram or iMessage, or through its optional HumanPods in-ear audio. The company describes the product as “iOS first.” These are vendor descriptions, not independent confirmation that each app integration works as advertised.

Which agents are planned?
Launch coverage names Meta’s Muse, Instinct, Grokbot, Claude and ChatGPT among planned integrations. GamesBeat reports that NatureOS’s store has more than 140 agents. These are launch-reporting claims; the available sources do not establish that every named integration is live, available in every region or independently tested.

What health measurements does Natura claim?
TechCrunch reports that Interface is intended to track heart rate, resting heart rate, heart-rate variability (HRV), sleep stages, daily movement, steps and skin temperature over time. Natura’s product page lists sleep, heart rate, HRV and activity.
Those are product claims, not evidence of measurement accuracy or clinical usefulness. The available reporting does not independently validate the readings, explain how they compare with medical devices or establish that the ring is suitable for health decisions.
What will Interface cost?
TechCrunch and GamesBeat reported a $99 early-launch price in 2026. TechCrunch says Natura plans to raise the price later. TechCrunch also reported a planned $9 monthly subscription after an initial free period of three to six months; GamesBeat describes a free plan or a $9-per-month subscription. These reported launch terms are not confirmed current billing terms, so check the checkout page for the price, free-period length and recurring charges before ordering.

If the $9 monthly plan applies after the free period, the ongoing subscription—not just the ring’s upfront cost—will determine the longer-term price. The sources do not establish which features require a subscription or whether a no-cost tier will remain available.
How long does the battery last?
TechCrunch reported Natura’s claim of six to twelve days per charge and about 100 minutes to recharge, with battery life depending on use. However, Natura’s product page says the final printed battery figure is still being finalized and that tested figures would be published before preorders. There is no independently tested battery result in these sources, so treat the range as provisional rather than a settled specification.
When can you order Interface?
The available dates conflict. Natura’s product page says preorders opened September 15, while TechCrunch’s October 8, 2026 report says preorders were expected the following month and shipping was slated for December or January. GamesBeat reports shipping in January 2027. The reports do not resolve whether ordering is currently open or which delivery date applies; confirm availability and the estimated ship date directly with Natura before paying.

What should you compare before buying?
Launch coverage places Interface in a market that includes health-focused rings such as Oura, Samsung Galaxy Ring, Ultrahuman and RingConn, as well as AI-focused wearables such as Pebble and Vocci. The available sources do not support a feature-by-feature ranking. For a practical comparison, check:
- Voice access: Whether press-to-talk agent use and the integrations you want are actually available.
- Health tracking: Which metrics each ring offers and what evidence exists for the accuracy of its readings.
- Battery and charging: Whether the manufacturer has finalized the specification and whether independent testing is available.
- Phone and reply compatibility: Which operating systems, messaging apps and audio accessories work in your region.
- Total cost: Upfront price, any free period, recurring subscription and the features included at each tier.
- Delivery: Current order status, estimated shipping date and the seller’s return terms.
What remains uncertain?
The reporting does not establish current subscription terms, final battery specifications, Android support or a confirmed shipping schedule. It also does not independently verify the health measurements or the advertised agent and messaging integrations. Treat these as questions to resolve on the current product and checkout pages, rather than assuming the launch descriptions are guarantees.
TechCrunch quotes Natura founder Carlo Edoardo Ferraris saying the company came to believe “you really want to have access to your agents 24/7.” Ferraris also described the ring’s health tracking, agent communication, meeting recordings, external memory and battery life as differentiators. Those are the founder’s descriptions of the product, not independently established comparisons. TechCrunch reports that Ferraris previously founded consumer-accessories company Rolling Square.
