Apple Watch Series 4 Defined Health Tech

The Apple Watch Series 4, released in 2018, is identified as a pivotal device that reshaped the landscape of modern health technology. Prior to its introduction, smartwatches and fitness trackers primarily concentrated on basic metrics like step counts, heart rate, and rudimentary sleep tracking, focusing more on fitness than comprehensive health monitoring. The Series 4 marked a significant shift, expanding the capabilities of wearables to encompass a broader range of health-related features. This evolution transformed the perception and utility of smartwatches, moving them from simple activity loggers to more sophisticated health management tools.
