Ultrahuman, a maker of smart rings, has launched its new "Ultrahuman Ring Pro." The company announced it and opened pre-orders in February 2026, and worldwide shipping, including in the United States, began on June 20. The ring offers a long battery life rated at up to 15 days, a heart-rate sensor reworked for better accuracy during sleep, and a new processor that runs machine learning directly on the chip. It pairs all of this with Ultrahuman's own AI, "Jade," which handles tasks such as detecting atrial fibrillation (AFib). The global price is 479 USD (about 77,000 yen), and the company is positioning the absence of any monthly subscription fee as a key difference from rivals.

A 15-Day Battery and a Dedicated Charging Case

The biggest improvement is battery life. By Ultrahuman's own figures, the previous "Ring Air" lasted 4 to 6 days on a single charge, while the Ring Pro is rated for up to 15 days. That is a substantial jump for a category where near-daily charging has been the norm.

A dedicated "Pro Charger" case has also been introduced. Carrying the ring in the case extends its usable time to up to 45 days. The case itself supports charging over USB as well as Qi wireless charging. It adds a "Find My Case" feature that uses proximity guidance to help locate it when lost, along with a built-in speaker. Because the ring and case communicate directly, Ultrahuman says software updates, diagnostics, and troubleshooting can all be carried out quickly.

Redesigned Heart-Rate Sensor and On-Chip Machine Learning

The sensor system has been rebuilt as well. The Ring Pro revises the architecture of its heart-rate sensor to improve signal quality during sleep and recovery (the body's recuperation after exercise). By refining the foundational measurement layer, it aims to capture more stable data even in low-movement situations such as sleep.

The processing has also changed. A new dual-core processor runs machine learning on the chip itself (on-chip ML) to speed up data processing and improve accuracy. It brings the idea of "edge processing" — running calculations on the device before sending data to the cloud — down to the scale of a ring.

For safety, the ring adopts a new mechanism called "ProRelease Technology." In an emergency such as finger swelling or injury, the ring can be cut apart more easily. Ring-shaped devices are often a source of worry because they can be hard to remove, so making them easier to take off when needed is reassuring.

The "Jade" Biointelligence AI

Alongside the Ring Pro, Ultrahuman has introduced a new AI called "Jade." The company describes it as a "biointelligence AI" that analyzes the user's health data and returns answers to questions and real-time insights.

Jade draws on a wide range of information, combining more than 120 "Blood Vision" biomarkers derived from blood tests, glucose trends from the "M1 CGM" continuous glucose monitor, and even environmental data. It runs in two modes: a standard "Standard" mode and a "Deep Research" mode that digs deeper into long-term trends.

The actual functions are delivered as in-app add-ons called "PowerPlugs" (plug-ins). They include detection of atrial fibrillation (AFib), a "Caffeine Window" that shows the best times to consume caffeine, respiratory health management, tracking related to GLP-1 (a hormone involved in appetite and blood sugar), the women's-health-focused "Cycle & Ovulation Pro," and management of migraines and Vitamin D, with the list set to grow. Jade and PowerPlugs are available to all users, including those in the United States.

Ultrahuman says user data is processed in a secure system designed to meet applicable data protection standards. Still, it is worth remembering that these readings are meant as a reference for health management and are not a substitute for medical diagnosis itself.

Pricing and the Subscription-Free Pitch

The global price is 479 USD (about 77,000 yen). The Pro Charger case is included for free, and at purchase you can choose either gold or black. The flow is to first request a free sizing kit to measure your finger before ordering, and the ring comes in several titanium finishes. Anyone who already owns a Ring Air can trade it in for a discount of up to 115 USD (about 19,000 yen).

What Ultrahuman emphasizes strongly is that no monthly fee is required. Some smart rings require ongoing payments to use their features, but the Ring Pro can be used without an additional subscription. CEO Mohit Kumar says the Ring Pro's battery life is three to four times that of the competition, and that by combining industry-leading hardware with Jade's AI, users can now take real-time action toward their health.

Summary

The Ultrahuman Ring Pro is a smart ring that bundles up to 15 days of battery, a heart-rate sensor tuned for accuracy during sleep, a new processor that runs machine learning on the chip, and the "Jade" AI that even handles atrial fibrillation detection — all for 479 USD (about 77,000 yen) with no subscription. From the safety mechanism that lets you cut the ring off in an emergency to the dedicated case that stretches usable time to 45 days, it pays careful attention to the practicality of a health device worn every day. As a one-time purchase with no recurring fees, how much health management can it take off your hands? For anyone considering a ring-shaped device, it looks set to raise the bar for the options on the table.
