Embodiments are directed to an apparatus that includes a weighing scale and external circuitry. The weighing scale includes a platform and processing circuitry. The platform includes force sensor circuitry and a plurality of electrodes integrated with the platform. The processing circuitry is electrically integrated with the force sensor circuitry and the plurality of electrodes and collect cardio-related physiologic data from the user and outputs at least portions of the cardio-related physiologic data as user data. The external circuitry receives user data from a plurality of weighing scales and pools user data for a plurality of users into user data sets for each user. The external circuitry further identifies a subset of the plurality of users with correlations, identifies and normalizes user data from the user data sets of the subsets of users based on prioritization data and normalization data, and provides the subsets of users of the social groups with access to a social group via respective scales of the subset of users.
