With a water resistance rating in Fitbit of up to 50 meters, the Charge 4 is built to withstand sweat, rain, and even swimming. Its durable construction ensures it can endure daily wear and tear without any issues.


Health and Fitness Tracking Features


Heart rate monitoring

The Fitbit sleep tracking capabilities are impressive, providing insights into sleep stages (light, deep, and REM) and offering a sleep score based on the quality and duration of sleep. This information is vital for users looking to improve their sleep habits and overall well-being.

2. Silent alarms

The device also features a silent alarm function that vibrates to gently wake users without disturbing their partner.


Activity Tracking

1. Step Counting and Distance Measurement

During my experience with the Fitbit Charge 4, I found its step-counting and distance measurement features to be highly accurate.

The device uses a 3-axis accelerometer to track steps throughout the day, providing real-time updates on your progress.

According to a study published in the Journal of Medical Internet Research, Fitbit devices have an accuracy rate of approximately 97% for step counting. In my personal experience, Charge 4 was consistent with these findings, making it a reliable tool for tracking daily activity levels.

2. Calorie Burn Estimation

The Fitbit Charge 4 estimates calorie burn based on your age, weight, height, and heart rate data, providing personalized insights into your daily energy expenditure.

While no fitness tracker can guarantee 100% accuracy, I found the Charge 4’s calorie burn estimation to be reasonably accurate when compared to other devices I’ve used.


Workout Modes and Automatic Exercise Recognition

1. Preloaded Exercise Profiles

Fitbit Charge 4 comes with over 20 preloaded exercise profiles, including running, cycling, swimming, and yoga. This variety caters to a diverse range of fitness enthusiasts and allows for a more accurate tracking experience.

Fitbit Charge 4 has a built-in GPS, which is a significant upgrade from its predecessor, the Charge 3. This feature allows you to track your pace and distance in real time during outdoor activities like running and cycling without needing to carry your smartphone. The GPS functionality performed exceptionally well during my testing, providing accurate and consistent data throughout various activities.

2. Route Mapping

The GPS integration also enables route mapping, allowing you to visualize your workout routes and analyze your performance over time. This feature was particularly helpful during my long runs, as it provided valuable insights into my pacing and consistency.
