Fitness trackers such as the Apple Watch, Fitbit Charge, and Garmin Forerunner are known to offer relatively accurate heart rate measurements. These devices use advanced sensors and algorithms to provide accurate readings during various activities such as running, cycling, and weight training. However, it's important to note that no fitness tracker is 100% accurate, and factors such as skin type, fit, and motion can affect the accuracy of heart rate measurements. **

One option for a fitness tracker with heart rate irregularity detection is the Fitbit Charge 4. This device has a built-in heart rate monitor that can detect irregularities in your heart rate, such as atrial fibrillation. It also has a feature called Active Zone Minutes, which tracks your heart rate during exercise to ensure you are working out at the right intensity. Additionally, the Fitbit Charge 4 has a long battery life and is water-resistant, making it a versatile option for tracking your fitness and monitoring your heart health. **
