Garmin Forerunner 970 Ranks Fourth in Apple Watch Ultra 4 Study
· By Endurance Wire
Apple’s latest internal study positions the Apple Watch Series 12 and Ultra 4 as leaders in heart rate accuracy, surpassing competitors like Garmin, Google Pixel Watch and WHOOP. Using the Polar H10 chest strap as a benchmark, the study evaluated performance across activities ranging from high-intensity interval training (HIIT) to daily routines. Notably, Apple’s devices demonstrated lower error rates, particularly in scenarios with rapid heart rate fluctuations. Chase the Summit examines these findings while addressing concerns about the study’s internal nature and the need for independent validation.
