Certain aspects of the disclosure are directed to an on-demand healthcare apparatus used to enrich the doctor-patient relationship, provide accessible specialized care, while also reducing costs. The apparatus includes a weighing scale including a platform and processing circuitry. The processing circuitry or a portion thereof is electrically integrated with a plurality of sensors under the platform and collects physiological data from the user while the user is standing on the platform. The processing circuitry aggregates scale-obtained data with user data from a plurality of user devices and/or medical devices, filters a database or a system of computer networks with the aggregated data in response to the aggregated data matching trigger data indicating the user is at risk for a health condition, and provides the aggregated data and filtered data to external circuitry accessible by a healthcare professional for review and for providing on-demand care.
