What is the most accurate smart watch for heart-health?
The Apple Watch Series 11 was the most accurate heart rate monitor during workouts. The Garmin Venu 4’s heart rate tracking has more data, ideal for serious training analysis. If steps and distance accuracy are your priorities, you don’t need an expensive smartwatch. For most people, wearing a smartwatch around the clock—including while sleeping—is a low-risk choice that can provide meaningful health and fitness insights. The key is to manage the real-world factors that matter most: strap fit, skin hygiene, nighttime settings, and sensible charging.
