Polar Flow: enter your weight
Polar calculates calories from heart rate, movement and the physical settings of your profile. The day summary in Polar Flow shows the calories of the whole day including resting metabolism.

Menus change with app versions – if an item is named differently for you, look for “profile” or “body data”.
Enter weight and height
Open physical settings
Polar Flow app → menu → “Settings” → “Physical settings” (on the web: your name top right → “Settings” → “Physical settings”).
Enter the values
Enter height, weight, date of birth, sex and training background and save.
Sync the watch
Sync after saving so the watch calculates with the new values.
Find the day's total calories
Open the diary
Polar Flow → “Diary” → tap the challenge day.
Activity summary
The day summary shows “Calories” for the whole day – including resting metabolism and all training sessions.
Enter the value
That daily value is your total energy for the challenge.
Screenshot for the proof
- Screenshot of the day summary with date and calories.
- Single training sessions show only their share – for the proof the daily value counts.
What counts as proof
The screenshot must show the total energy of the challenge day – resting plus active – with the date visible. The value is read once by an AI model and never stored; the certificate follows.
Common questions
- Does the sum of my training sessions count?
- No. The challenge counts the day's energy including resting metabolism and everyday activity, not just training.
- Where do I change the weight on the watch?
- Depending on the model under Settings → Physical settings. The app overwrites these values at sync.
