Your whole day.
Every component.

Explore what goes into your calorie burn.

Resting

The energy behind your everyday.

Your baseline uses body measurements, with lab body composition or measured resting metabolism when available.

Body measurements

Movement

Everyday activity, accounted for.

Steps and walking data inform movement burn. Overlapping workout activity is reconciled to avoid counting it twice.

Steps + distance

Workouts

Different workouts. Different math.

Strength, cardio, and intervals use different models. Heart rate, pace, power, sets, and reps inform estimates where available.

Activity-specific models

Digestion

Food takes energy, too.

The thermic effect of food is estimated from logged protein, carbohydrates, fat, fiber, and alcohol.

Macro-aware digestion

Personalization

A model that learns from you.

Logged intake and qualifying weigh-in trends gradually calibrate your burn estimate as enough data becomes available.

A few good questions.

How does burn personalization work?

MinervaOS uses logged intake and qualifying weigh-in trends to gradually adjust its burn estimate. Calibration starts once enough data is available.

Do I need a wearable?

No. You can log food and workouts without one. Apple Health and supported wearable data provide additional signals for the model.

Are these measured calories?

They are estimates. The app shows the components behind the number; it does not directly measure metabolism.

Is there a free trial?

Eligible new subscribers can try MinervaOS free for 7 days. After the trial, your selected plan renews automatically unless canceled. See pricing.
