Yes. With its upgrades and additional features, the Fitbit Charge 5 is definitely a lot more accurate than most smartwatches and fitness trackers. Although accuracy is not everything, you can rest assured that this device reliably detects, identifies, and records your workout, steps, and heart rate, and sleep score. And, the best part is the daily readiness score which is a consolidated, actionable number that lets you know your readiness for the day's workout.
