Jinri Yixiu launches ISHO Ring and iFlow to build an AI sleep-tech stack

Jinri Yixiu, a Chinese sleep-tech startup, launched two AI sleep products on October 29: the ISHO Ring smart ring and the ISHO iFlow smart temperature-control system. Founder and CEO Wang Teng also introduced a personal sleep-health AI stack built around an agent-centric app and the company's in-house ISHO physiological-signal model.

Wang framed sleep health as a systems science that requires sleep research, AI algorithms and hardware engineering to work together. The company's plan pairs a hardware matrix, running from physiological sensing on the finger to active control of the sleep environment, with an AI loop it describes as monitor, analyse, intervene and evolve, aiming to build a leading global AI sleep-tech brand within five to ten years.

The ISHO Ring uses aerospace-grade titanium formed as a single piece, and the company claims an industry-first ambient-light sensor behind a sapphire window produced through 14 process steps. It debuts the Apollo 330B Plus flagship chip with on-device AI, 32MB of storage for seven days of offline data, and a claimed 6-10 day battery life.

The ring tracks 18 metrics through sensor fusion, while the Pro version's charging case adds a five-in-one environmental sensor for CO2, temperature, humidity, noise and indoor light, combining body signals with bedroom conditions. The app rolls sleep, activity and recovery into a 0-100 energy score and uses an on-device agent to explain sleep reports and suggest daytime energy management.

The iFlow handles intervention. Two BCG sensing bands capture heartbeat, breathing and movement without wearable contact and support independent monitoring for two sleepers; eight bed-temperature sensors and a room sensor feed fine-grained control, and the Pro adds a 512-point flexible pressure array to detect posture changes. A MediaTek Genio 420 controller with 7.2 TOPS runs models locally to turn sleep state into temperature decisions, executed by a TEC module, four water-circulation loops and a 600W cooling system that allow separate temperature zones for each side of the bed.

Jinri Yixiu also announced a collaboration with Shang Xia, a Chinese lifestyle brand, on custom bed linens, throws and cushions aimed at premium home settings.

The launch fits a broader shift in sleep technology from passive tracking to active intervention, and shows consumer AI hardware spreading from the wrist to the finger and the mattress. Running models on-device to trade compute for real-time response is a common way to sidestep cloud latency and privacy concerns, but the results still hinge on sensor accuracy and independent validation.

The company did not disclose pricing, retail dates or medical-grade certifications for either product, details that will shape whether they move from demo to volume sales.
