REFERENCE TOOLS

Four calculators for reading your own numbers.

Enter a reading, get a plain-language reference note, and optionally save it to a private log kept only in this browser.

Blood Pressure Interpreter

Enter a systolic and diastolic reading in mmHg. The interpreter maps it against commonly referenced resting ranges — it does not account for white-coat effect, medication, or measurement technique.

Glucose Levels

Select the timing of your reading — fasting, two hours after eating, or random — since reference ranges shift depending on context.

BMI

A population-level screening figure from weight and height. Switch units freely — the calculation adjusts automatically.

Heart Rate Zones

Add a resting heart rate for the more precise heart-rate-reserve method, or leave it blank for a straightforward percent-of-max estimate.

Your vital log

Stored only in this browser. Clearing it removes it permanently.
