Methods, systems, apparatuses, and/or devices for determining a physiological condition for an individual. The methods, systems, apparatuses, and/or devices may include a housing, a sensor interface, a processing device, and a display device. The sensor interface may be integrated into the housing. The sensor interface include a first sensor operable to take a plurality of physiological measurements of a user over a period of time. The processing device may be coupled to the sensor interface. The processing device may be operable to receive the plurality of physiological measurements； determine a change in the plurality of physiological measurements； and determine a hydration condition measurement for a body based on the change of the plurality of physiological measurements. The display device may be integrated into the housing. The display device may be operable to display a hydration condition indicator associated with the hydration condition measurement.
