Ultrahuman Ring Pro Smart Ring

The Sleep Index breaks your sleep down to what actually matters – how long you sleep, how well you recover, and how deeply your body resets. Track sleep duration, Resting Heart Rate (RHR), restfulness, and sleep stages including REM, Deep, and Light sleep to understand not just how much you slept, but how effectively.

Dynamic Recovery adapts to your body in real time, reading when you're ready to perform and when recovery is non-negotiable. It goes beyond scoring by offering actionable recommendations, then recalibrates your recovery score as you implement them so you understand exactly when to push and when to rest.

Stress Rhythm tracks how your heart responds over the course of the day, quietly analyzing HR, HRV, and RHR against the backdrop of your circadian rhythm. The result is a clear signal of your current state: stimulated, relaxed, or stressed – so you know when to lean in and when to step back.

Movement Index is built to optimize daily movement, not just workouts. By closely tracking steps, workouts, calories, and non-exercise activity, it helps improve glucose metabolism and increase all-day energy usage even when you're outside your training routine.

Ultra Age is a science-backed aging marker powered by your physiology. It's a single insight derived from your Brain Age, Pulse Age, and Blood Age as contributors. Track how lifestyle changes, sleep, exercise, and nutrition can impact your aging trajectory and turn insight into your competitive edge against time.
