The Ring AIR is Ultrahuman's flagship lightweight titanium smart ring, tracking sleep stages, heart rate, heart rate variability, skin temperature, and movement to surface recovery, sleep, and movement insights. Unlike subscription-gated rivals, Ultrahuman offers the ring without a mandatory recurring fee. It integrates with the company's broader ecosystem so wearers can view ring data alongside glucose and blood-biomarker readings, and contributed the majority of the company's revenue, with ring sales surging roughly 7x year-over-year in FY25.
The M1 is a continuous glucose monitor, originally launched as the Ultrahuman Cyborg metabolic stack, that lets users see how food, exercise, sleep, and stress affect their blood-glucose levels in real time. A sensor worn on the arm streams glucose data to the app, which pairs it with personalized guidance on metabolic health. It anchors Ultrahuman's metabolism-first positioning, giving the company a hardware layer for blood-sugar visibility that most smart-ring competitors do not offer.
Blood Vision is Ultrahuman's biomarker-testing service that analyzes 100-plus blood markers — covering metabolic, hormonal, cardiovascular, and nutritional health — and feeds the results into the same app as ring and glucose data. Users receive longitudinal tracking and personalized recommendations tied to their wearable metrics, turning episodic lab work into a continuous, app-native view of internal health. It rounds out Ultrahuman's stack as the deep-diagnostic complement to its always-on ring and glucose sensors.
