Informational biometric portal — not a diagnostic service

See your vitals the way a lab reads them

Vitalvalue turns standard wellness formulas into a readable dashboard — heart rate zones, hydration targets, energy needs, and sleep architecture, worked out from your own numbers, explained in plain terms.

Four tools, one dashboard

Each calculator runs on a published formula, shows its assumptions, and explains where the estimate can be off.

MOVEMENT & RECOVERY

Consistency, not intensity, is what most preventive guidance comes back to.

Small, trackable habits

Vitalvalue focuses on the handful of numbers that are simple to measure at home and genuinely useful over time — not one-off scores, but trends worth watching.

Track trends, not single readings

A single number rarely means much on its own — direction over weeks matters more.

Understand the formula, not just the output

Every tool shows its method and its known margin of error.

Bring it to a clinician, not a diagnosis

These tools are a starting point for conversation, not a substitute for care.

Guides worth reading once

Sixteen short guides across preventive screening, metabolic health, movement, and sleep — written to be read in one sitting.

All guides
Preventive Screening

Reading Your Annual Blood Panel

A plain-language walkthrough of common lipid and metabolic markers.

Metabolic Health

How Insulin Sensitivity Works

Why blood-glucose regulation changes over time and what shifts it.

Movement & Recovery

Zone-Based Cardio Training

How heart-rate zones are defined and how to estimate your own.

Sleep & Stress

The Stages of Sleep Architecture

What happens across light, deep, and REM sleep cycles.

Start with one number

Pick a single calculator, see where you land, and read the guide that explains it. That's the whole first step.
