Google Fit & Fitbit: enter your weight
Both apps show calories burned as a daily value including resting metabolism – exactly the number the challenge needs. The prerequisite is a current weight in the profile.

Menus change with app versions – if an item is named differently for you, look for “profile” or “body data”.
Enter weight and height
Google Fit
Google Fit → “Profile” tab → fill in “Weight” and “Height”. A new weight entry also works via “Journal” → “+” → “Add weight”.
Fitbit app
Fitbit → “Today” tab → profile picture → “Personal” (or “Account settings”) → enter height and weight.
Save and sync
Sync once after saving so the watch or band uses the new values.
Find the day's total calories
Google Fit
Home → tap the “Cal” value → day view. Google Fit counts total energy expended here, including resting metabolism.
Fitbit app
“Today” → tap the “Calories burned” tile → day view. The value includes resting metabolism.
Check the day
Move to the challenge day and make sure the date is visible.
Screenshot for the proof
- Screenshot of the day view with date and the total calories.
- After midnight sync first, then open the completed day.
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
- Google Fit or Fitbit – which one counts?
- Both. Use the app your device stores its data in. Both show the daily total.
- Why is my value already at 1,800 without any sport?
- That is the resting metabolism the app calculates from weight, height, age and sex. It counts – even while you sleep.
