Smart health checkers are portable medical devices that provide health assessments and recommendations by measuring physiological parameters of the body. These devices typically use sensors to measure metrics such as blood pressure, heart rate, and oxygen saturation, and store the results on the device or sync them to a smartphone app via the cloud. The apps can use that data to generate health reports and recommendations, such as how to improve diet or exercise habits.
But the smart health checkers on the street may not be as accurate as the devices found in hospitals or clinics. In addition, if you have any health concerns, consult a doctor or other medical professional rather than relying on these devices for self-diagnosis.
