What is activity tracker?
An activity tracker is a type of electronic device that can be used to monitor certain human activities such as walking or running, sleep quality, or heart rate. An activity tracker can be a smartwatch or other small device that is connected to a local network or otherwise connected to an IT system.
An activity tracker is also known as a fitness tracker.
Activity trackers can measure the number of steps someone takes, as well as their heart rate and other indicators. Many of these portable devices can port data directly to a smartphone or PC. This means that activity trackers have a lot of potential to change the way people monitor their health and fitness.
Many top activity trackers, such as the best-selling Fitbit models, are compatible with Apple and Android mobile systems (as these are the two largest types of smartphone platforms) and can also be connected to Bluetooth to store data on upload a computer. Activity trackers help with diseases like obesity and sleep apnea. In general, activity trackers have become part of the 'next generation' of portable computers that are changing the way people live and work in the 21st century.
