Where can I find the calorie count in the WHOOP app?
It's very simple. To access your calories burned, follow these two steps:
- Open the’WHOOP application on your smartphone.
- Scroll down to the section Calories.

There you'll find a daily summary of your total calorie expenditure. The app also breaks down the distribution among your calories at rest (tone BMR (estimated) and your active calories, burned during exercise.
An important point: WHOOP only tracks calories burned, not the calories consumed. Nothing related to nutrition. For that, you'll need to use a dedicated nutrition app.
In the app, calories are still a secondary consideration. The focus is primarily on three metrics:
- the sleep (Sleep)
- The recovery (Recovery)
- L'effort (Strain)
We'll tell you more about these three features in our full review of WHOOP.
How does WHOOP calculate calories burned?
WHOOP provides a estimate based on your heart rate measured continuously based on your biometric data. Specifically, the wristband combines several types of information:
- Your personal data information entered into the app (age, gender, height, weight)
- Your physical activity data (duration, intensity of the exercise)
- Your basal metabolic rate estimated (BMR)
- The heart rate variability (HRV) and resting heart rate
The calculation is based on scientific models rather than relying on simple, generic averages. The goal is to avoid overestimates and to get as close as possible to your actual effort.
This video clearly shows the measurements taken by the wristband on a daily basis:
How accurate is WHOOP calorie tracking?
WHOOP itself emphasizes this point: the The calorie counts shown are estimates, not an exact figure. To date, the company has not released no official accuracy percentage.
The cost is calculated based on your heart rate continuously, from the heart rate variability (HRV), skin temperature, and motion detected by the accelerometer.
The more the wristband knows about you (age, weight, resting heart rate), the more accurate the estimate becomes.
The sensor remains the most reliable way to track a trend over several days ...in order to give an exact figure, down to the calorie.
To get a more accurate picture of your nutrition, it's best to cross-reference this data with a dedicated app.
