Smartwatches and activity wristbands are smart wearable devices that offer a wide range of functions to monitor health and physical activity and make daily life easier. Smartwatches often combine the features of a traditional watch with the rich functionality of a smartphone, such as receiving calls, reading messages and controlling music. They usually also include a range of sensors, such as a heart rate monitor and accelerometer, for health monitoring.

Activity wristbands focus in particular on monitoring physical activity, such as the number of steps taken, calories burned and quality of sleep. They can also send exercise reminders and encourage the user to achieve daily exercise goals.

A range of accessories are available for smartwatches and activity wristbands, including interchangeable wristbands in different materials and colours. Some accessories can provide protection against scratches and shocks. In addition, charging stations and back-up power supplies can be useful to keep the devices in working order.
