A smart band is a health tracker that you wear around your wrist, just like a watch or smartwatch. These health trackers don't have a screen, so you don't get distracted by smartphone notifications while working or working out. With a smart band, you can learn more about your health and get tips on how to improve your lifestyle. You can find all data and tips in an app on your smartphone. You can choose between fitness trackers from brands like WHOOP and Garmin. Note: with WHOOP, you pay for 1 year. After a year, you'll have to pay subscription costs again.
