More signalFor your longevity insight
The ring streams heart rate, heart rate variability, blood oxygen, blood pressure, breathing rate and movement into Phenome, so your microbiome and genome are read in the context of how you actually sleep, move and recover.

Every reading is measured against your own baseline rather than an average, so the ring has to build one first. Here is what arrives, and when.
What the ring measuresNight 1Sleep, decoded
- Time in every stage
- Resting heart rate through the night
- A sleep score waiting each morning
Week 1Your normal, measured
- Heart rate variability against your own usual range
- Blood oxygen and breathing rate, each with its range
- Enough nights to know what normal looks like for you
Month 1Trends, not days
- Every reading by the day, week and month
- Blood pressure through the day, with its highest and lowest
- One bad night stops looking like a trend
Month 3Read in context
- Months of continuous signal, not a snapshot
- Joined to your genomic and microbiome data
- Read together by Phenome
Timings are what a consistently worn ring gives. Wear it less and the baseline takes longer.
How to wear itOn the index or middle finger, overnight and through the day.
