A reference layer for people who own wearables and want to understand what their metrics actually mean — not what to do about them.
Most wearable documentation tells you what a number is. Very few sources tell you whether your number is good, bad, or typical — relative to people your age and sex, measured under controlled conditions.
Nyxova exists to provide that reference layer. Reference information and calculators with different levels of source support. The HRV table’s exact provenance is unverified, and the biological-age calculator is Nyxova’s own unvalidated model. Device guides that explain algorithms, not just outputs.
Nyxova is not a health advice site. We do not tell you what to do with your metrics. We do not diagnose conditions. We do not recommend supplements or interventions.
We are a reference resource. Think of us as the data layer between your wearable app and your own judgment — or a conversation with a qualified clinician.
Sources and limitations are described on the relevant pages. The exact derivation of the configured HRV table is not documented; do not treat its outputs as verified population percentiles.
The biological-age tool uses fixed settings chosen in Nyxova’s implementation, not a published validated age formula. Its weights and limitations are shown on the calculator page. Other tools describe their own methods separately.
