Ultrahuman
Subscription-light smart rings and environmental sensing for sleep, recovery, circadian timing, and self-experimentation.
What they're known for
A health-tracking platform that extends from the finger into the bedroom, pairing Ring AIR biometrics with environmental variables such as CO₂, particles, light, humidity, and noise.
Ultrahuman Ring AIR tracks sleep, movement, heart-rate trends, HRV, temperature, and recovery in a compact smart-ring format. The software layer adds targeted PowerPlugs and circadian-oriented guidance rather than relying on a single universal score, while Ultrahuman Home extends the same app into environmental sensing for CO₂, VOCs, formaldehyde, particulate matter, temperature, humidity, light spectrum, UV, sound, and presence. The combination is unusual because personal sleep signals and room conditions can be viewed inside one platform, though environmental correlation does not by itself establish causation.
