It automatically recognizes up to 24 users, so your family can step on and see personalized data without manual switching. Sync with the Fitdays app to view long-term charts and track progress over time. Features like baby mode for infants and support for multiple weight units make it practical for diverse needs.
Use it to monitor health trends, set fitness targets, or keep an eye on family members' wellness, all with clear, actionable data at your fingertips.
