Comparison between Fitbit's Charge HR and Microlife's Wrist Watch for Healthcare
Year: 2025
Type: article
Abstract: In this study, two commercially available pulse rate monitoring wrist watches, the Fitbit’s Charge HR and the Microlife’s wrist watch, are compared for testing under a number of controlled situations, including resting and post-physical activity. This study is driven by known variability in wearable heart-rate sensing caused by motion artifacts, sensor location, and physiological variances, as described in previous validation studies, rather than assuming measurement errors. Therefore, the absence of context-specific comparative assessments of consumer-grade pulse monitoring devices among local populations and real-world usage situations is the research gap that this study attempts to fill. This study attempts to quantify accuracy discrepancies, uncover scenario-dependent performance variances, and give empirical evidence to support these findings by methodically comparing Fitbi’s Charge HR and Microlife’s wrist watch readings against standardized reference values. Accuracy is measured by testing strategies, testing strategies which are used in this research work are Black-box testing. Black-box testing methods include both hardware testing and software testing.
