ISHO, a sleep technology startup based in Beijing, was founded by former Xiaomi executive Wang Teng. At an event held in Beijing on October 29, the company introduced its first hardware products: the ISHO Ring smart ring and the ISHO iFlow sleep temperature regulation system. Both devices integrate via the ISHO application.
In a press release dated October 30, ISHO announced plans to expand beyond China and revealed its participation in the CES 2027 exhibition in Las Vegas in January.
Features of the ISHO Ring Smart Ring
The ISHO Ring is positioned as a monitoring device. According to the company, it features a TC4 titanium alloy casing, an Apollo 330B Plus chip capable of local artificial intelligence, OSRAM photodiodes for optical heart rate measurement, analog front-end components and a skin temperature sensor from Analog Devices, as well as a six-axis motion sensor. The ring has 32MB of memory, sufficient to store data for up to seven days in autonomous mode, and a stated battery life of six to ten days.
The ring tracks 18 different metrics, including sleep stages, activity, recovery, and ambient light exposure, aggregating them into an 'energy score' in the app. There are two versions of the ring with the identical core set of health functions. The Pro model includes a charging case equipped with sensors for carbon dioxide, temperature, humidity, noise, and illumination, which the company claims are used to correlate bedroom conditions with sleep data. ISHO emphasized that this ring is not a medical device.
Description of the ISHO iFlow System
The ISHO iFlow system is presented as a sleep intervention product—a mattress cover that supports regulating the surface temperature of the bed throughout the night. It uses two sensor strips for ballistocardiography and body temperature sensors to track heart rate, respiration, and movement without the need to wear a wearable device. The system is controlled by a MediaTek Genio 420 controller with 7.2 TOPS of computing power on the device and a thermoelectric module that independently heats or cools each side of the bed. The company claims that the system adapts the temperature according to the sleep stage to prolong deep sleep, although independent data on this effect has not yet been published.
In terms of software, ISHO Intelligence combines its proprietary physiological signal model with a personal AI agent that generates energy recommendations for both sleep and wakefulness. The company notes that the data obtained from the ring and the mattress system are intended to complement each other, forming a cycle of monitoring, analysis, adjustment, and improvement.
Pricing and Availability
The initial retail price in China is set at 1,799 RMB for the ISHO Ring and 2,199 RMB for the Pro model. The iFlow system starts from 9,999 RMB, with the Pro version priced at 12,999 RMB, while the edition co-developed with SHANG XIA is offered at 15,999 RMB. Pre-orders were opened during the launch; the ring is scheduled to ship from November 11, and iFlow from December. ISHO has not yet disclosed international prices or delivery dates.
ISHO was established in January 2026 and states that it has over 100 employees working on AI algorithms, clinical medicine, and sleep science.
