Certain aspects of the disclosure are directed to an apparatus including a scale and external circuitry. The scale includes a platform, and data-procurement circuitry for collecting signals indicative of the user's identity and cardio-physiological measurements. The scale includes processing circuitry to process data obtained by the data-procurement circuitry, generate cardio-related physiologic data, and send user data to the external circuitry. The external circuitry validates the user data as concerning a specific user, correlates the user data with a user profile of the user, provides a clinical indication using the user data, and controls access to the user profile by allowing access to the clinical indication and the user data to or by a physician and not allowing access to the clinical indication to the user until the user provides an input indicating interest in the clinical indication and the physician provides a prescription for the clinical indication.
