6.3 User Modes (Athlete Mode, Baby Mode)

• Baby Mode: Allows you to weigh an infant or small child. First, weigh yourself, then step off. The scale will zero out. Step back on holding the baby, and the scale will calculate the baby's weight by subtracting your initial weight.

Select these modes within your profile settings in the FitDays app.
