What is the difference between a smartwatch and a smartband?
The difference between a smartwatch and a smartband is that the former is a more independent device, while the latter needs an app on your smartphone to function.
In simplest terms, a smartwatch, just like a smartphone, has numerous functionalities. Most often, it has a separate internet connection and often a SIM card that provides a cellular network connection. The application in the smartphone is an important support and development of the smartwatch capabilities. A smartwatch is a wristwatch with functions beyond time measurement. These devices are able to track the user's physical activity, location, and other health-related information. Smartwatches typically have an electronic display that can be used to display real-time data. Some models can also display alerts for incoming calls or messages.
A smartband, on the other hand, is mainly designed to measure activities related to sports - such as distance traveled, number of steps or calories burned and the owner's daily life.
A smartwatch is a wearable device that can be used to interact with others, receive notifications, track health and more. It is more of a standalone device. A smartband is worn on the wrist and can also be used to track health.
Are smartwatch and smartband measurements reliable?
Both devices are equipped with sensors using photoplethysmography (PPG) to measure pulse and light-sensitive photodiodes to measure blood oxygen levels. However, other parameters such as blood pressure, fatigue, body fat, etc. are based on algorithm calculations. These devices are not medically certified. Therefore, the indications of smartwatch, smartband and their apps cannot be an indication for a doctor or treatment. They can only be an additional suggestion to perform detailed tests and analysis.
Some devices are also equipped with sensors to measure temperature (on the wrist). More advanced models allow simple ECG (ECG) measurement by closing an electrical circuit (with the finger of the other hand, touch the sensor on the watch, thus closing the circuit around the chest).
