Athlete Mode
For individuals with a higher muscle mass and lower body fat percentage (e.g., athletes), activate the 'Athlete Mode' in the Fitdays app profile settings. This adjusts the algorithm for more accurate body composition analysis.

Baby Mode
To weigh an infant or pet, first weigh yourself, then hold the baby/pet and step on the scale again. The app will calculate the baby's weight by subtracting your weight from the combined weight. This feature is managed within the Fitdays app.
