Natra Unveils Interface AI Smart Ring Priced at $99

Natra, a hardware and artificial intelligence startup, has announced plans to launch a new wearable ring called Interface priced at $99. According to TechCrunch, the device aims to let users interact with multiple artificial intelligence agents, capture ideas, and control devices without taking out a smartphone, while simultaneously tracking key health metrics such as heart rate, sleep, and physical activity.

Interface Ring Features and Artificial Intelligence Integration

The Interface ring provides a physical button to access artificial intelligence agents rapidly. TechCrunch reported that the device will support integration with several major AI platforms and applications at launch, including Meta’s Muse, Instinct, Grokbot, Claude, and ChatGPT. Users can direct specific tasks to different agents, such as asking Claude to write code or Instinct to schedule an appointment.

Users can initiate running workouts, check daily schedules, or reorder household products simply by speaking. Responses from the AI agents are delivered through connected headphones, an iPhone Live Activity, or the company’s Nature OS application.

Hardware Design and Health Tracking Capabilities

The startup was founded by Carlo Eduardo Ferraris, who previously established tech accessories maker Rolling Square. The device is built to be worn continuously, including during sleep and showers.

Alongside its artificial intelligence functions, the ring includes comprehensive health monitoring tools. TechCrunch stated that the sensor suite measures resting heart rate, heart rate variability, sleep stages, daily movement, step counts, and skin temperature trends. Natra noted that the internal battery lasts between 6 and 12 days depending on usage intensity, and a full charge takes 100 minutes.

Pricing Strategy and Market Release Timeline

Natra plans to open pre-orders in November, with product shipments scheduled for December or January. Al Shorouk confirmed that the initial retail price is set at $99 to build an early user base, though the company may raise the price later. Following a free trial period lasting between three and six months, Natra intends to introduce a monthly subscription fee of $9.

The smart ring market currently features wellness-focused competitors like Oura, Ultrahuman, and RingConn, alongside AI-centric alternatives from Pebble and Foci. Ferraris stated that Interface differentiates itself by merging biometric tracking, AI agent connectivity, meeting recording, and extended battery life into a compact form factor.
