How it works

Check your Body Mass Index and category in seconds. Equil tracks it alongside the metrics BMI can't see, like recovery and glucose.

BMI uses only your height and weight, so no age or sex is needed. The formula and healthy ranges are the same for everyone.

Where Equil comes in

This is a static estimate. Equil tracks it automatically and adjusts in real time as you eat, train, sleep and recover.

Frequently asked questions

What is a healthy BMI?

For most adults a BMI of 18.5 to 24.9 is the healthy range. Below is underweight, 25 to 29.9 is overweight, and 30 or above is obese.

Is BMI accurate for athletes?

No. BMI cannot tell muscle from fat, so a muscular person can read as overweight. Use it as a rough screen, not a verdict on your body.

Does BMI use age or sex?

Standard adult BMI uses only height and weight. That is why it is a rough guide; body composition and waist size tell you more.
