Today Yixiu's Wang Teng launches the ISHO Ring smart ring and iFlow temperature control system, taking aim at Oura and Eight Sleep

Sleep, a scenario that occupies one-third of life, is becoming a new battleground for AI hardware competition. On October 29, ISHO (Jinri Yixiu) released two flagship sleep-tech products in Beijing—the ISHO Ring smart ring and the ISHO iFlow smart temperature control system—and launched its personal sleep health AI technology system, ISHO Intelligence.

After smart wearables long focused on "the 16 waking hours," Jinri Yixiu is attempting to extend its technological capabilities to "the 8 hours of sleep." Wang Teng, founder and CEO of Jinri Yixiu, said that in the past sleep products only monitored and did not intervene, making it difficult for them to become a large market. The maturation of AI capabilities, however, has made a closed loop of "monitoring—analysis—intervention—evolution" feasible.

Moving from passive monitoring to active intervention. The underlying logic of this choice lies in the data quality advantage of the sleep scenario. Wang Teng said during a group interview that when people sleep, they are completely relaxed and basically motionless, so signal acquisition quality is far higher than during the day.

As Jinri Yixiu's first health monitoring product, the ISHO Ring has been examined against Oura from the moment it was unveiled. Wang Teng previously stated clearly on Weibo: "Compared with Oura, we will be more cost-effective."

In terms of hardware specifications, the ISHO Ring is more aggressive in its component loadout: it is the world's first to feature the Apollo 330B Plus chip, is equipped with 32MB of storage, supports independent on-device AI operation, and offers 6 to 10 days of battery life. By comparison, the Oura Ring 5 has a maximum battery life of 8 days.

The more critical difference is the charging model. Oura's core health analysis features rely on a subscription to unlock, at $5.99 per month or $69.99 per year, and non-subscribers can only view three basic daily scores. The route chosen by Jinri Yixiu is to make basic features free, with charges only for some future AI features that consume tokens.

However, Oura's first-mover accumulation still cannot be ignored. The ISHO Ring mainly uses multi-sensor fusion to continuously monitor 18 data points. Notably, however, the sensing charging case of the ISHO Ring Pro also integrates five-in-one environmental monitoring of CO₂, temperature, humidity, noise, and indoor light, combining body and environmental monitoring directly in a rare way.

In the smart ring track, Wang Teng's judgment remains rational. He cited data saying that the global combined scale of smart wearables watches and bands exceeds 100 million units, while the smart ring market is currently still in the tens of millions. In the early days, constrained by semiconductor processes and device miniaturization, the form factor and experience were not yet mature. As processes mature, the differentiation of rings will become sufficiently obvious, and in the future there is an opportunity to reach a scale of tens of millions or even larger. He also emphasized that the entry of leading tech companies will jointly expand the market influence of this category.

If the ring solves "understanding one's state," then ISHO iFlow attempts to solve "changing one's state." The most direct global reference for this category is Eight Sleep. The latest generation of Eight Sleep's Pod 6 starts at $1,999 for the single version and $2,699 for the standard double version, and still requires an additional Autopilot subscription fee (starting at $199 per year) to unlock full automatic temperature control and health analysis features.

iFlow's pricing strategy clearly targets this price band. It starts at 9,999 yuan, with the Pro version starting at 12,999 yuan and the co-branded edition starting at 15,999 yuan. Wang Teng acknowledged during the group interview that similar products from competitors are priced in China in the range of 18,000 to 24,999 yuan, and iFlow's pricing is "roughly 60% to 70%."

In terms of technical route, both iFlow and Eight Sleep adopt an architecture of non-contact bed-surface monitoring plus active temperature control, but the implementation differs. The Eight Sleep Pod 6 increases sensor density to nine times that of the previous generation, with 18 biosensors on each side, and relies on water circulation for temperature regulation; the Hub is half the size of the previous generation and can be hidden under the bed.

iFlow, by contrast, uses dual BCG sensing bands to capture heartbeat, respiration, and body movement, together with 8 body temperature sensors and 1 bedroom temperature and humidity sensor for zoned collection; the Pro version adds a 512-point flexible pressure sensing array to identify sleeping posture. On the temperature regulation side, it uses TEC semiconductor modules plus water circulation, and the Pro version is upgraded to six groups of TECs with 900W of heat dissipation power.

Wang Teng places considerable importance on iFlow's monitoring accuracy, stating that the statistical data accuracy is "higher than Apple Watch," on the grounds that the bed's BCG piezoresistive sensors are continuously powered and collect full time-series data, whereas the watch's PPG is a sampled signal. However, he also acknowledged that the product's boundaries are clear: it cannot collect data once away from the bed and cannot replace a smartwatch.

Beyond the two hardware products, Jinri Yixiu also simultaneously launched the ISHO Intelligence personal sleep health AI technology system, including an App with ISHO Personal Agent as its core capability and a self-developed physiological signal large model. According to its vision, the ring collects physiological and sleep information throughout the day, the temperature control system provides non-contact bed-surface monitoring, the two sets of data complement each other to improve accuracy, and then the Personal Agent completes state determination and outputs recommendations.

Wang Teng mentioned that the team had previously done a data fusion demo, and after fusing the two sets of data, the accuracy of ISHO Intelligence will be even higher in the future.

"Being free early on is because the data volume and knowledge base are not yet sufficient; only after report accuracy and positive feedback improve will there be the ability to charge," Wang Teng said.

At present, Jinri Yixiu has chosen a path that is heavier and longer than that of most wearable manufacturers: the smart ring targets Oura with differences in hardware specifications and no subscription, the temperature control system targets Eight Sleep on price and localization, and an AI system is then used to connect the two.

To truly build the entire system, the timetable Wang Teng gave is 5 to 10 years. Moreover, whether this path can succeed still depends on two variables: whether the ring category can complete market education with the entry of leading manufacturers, and whether the closed-loop experience of software-hardware synergy can truly be perceived by users as "effective."
