The Fitbit Charge 4 is a versatile fitness tracker that offers a range of features designed to help you monitor and improve your health. With built-in GPS, heart rate monitoring, sleep tracking, and swim tracking, it's a robust tool for anyone looking to stay active and healthy.

One of the standout features of the Fitbit Charge 4 is its built-in GPS. This allows you to track your pace and distance during outdoor activities like running, cycling, and hiking. The workout intensity map in the app shows your heart rate changes along your route, providing valuable insights into your exercise performance.

Users have praised the sleep tracking feature, which provides detailed insights into your sleep stages and offers a Sleep Score to help you understand how well you slept. The customizable alarms that wake you up from light sleep are also a hit, making mornings easier to handle.

However, some users have reported issues with the GPS connectivity. While it works well when it connects, there are times when it fails to do so, leading to inaccurate route and distance measurements. This can be frustrating for those who rely on this feature for their workouts.

The battery life is generally good, lasting up to 7 days on a single charge. However, using the GPS can significantly reduce this duration. The device is also swimproof and water-resistant up to 50 meters, making it suitable for tracking swims and wearing in the shower.

Despite its many features, some users have experienced durability issues with the band connector breaking off after extended use. While some have resorted to super glue as a temporary fix, this highlights a potential area for improvement in future models.

Overall, the Fitbit Charge 4 is a solid choice for those looking for a comprehensive fitness tracker with advanced features. While it has its drawbacks, its benefits make it a worthwhile investment for anyone serious about their health and fitness journey.
