Summary:
- Fitness trackers like Fitbit and Apple Watch have become very popular in recent years, as they allow people to monitor their daily physical activity and step count.
- These devices use sensors to automatically track the number of steps a person takes each day, which can help motivate them to be more active and reach their fitness goals.
- However, research has shown that the step count data from these trackers may not always be 100% accurate, and people should use the information as a general guide rather than relying on it completely.
