Why Do Smartwatches Have Different Features Internationally Even When Bought In The US?

In 2025, Samsung announced that its sleep apnea feature on a variety of Galaxy Watch devices would soon be available globally, expanding to over 34 new markets with a software update. In 2024, nearly a year prior, the feature received FDA approval in the United States, allowing it to be activated and used here much earlier. But once you start adding health and medical functions, it becomes something more. In the United States, the Food & Drug Administration (FDA) regulates medical devices and products. So, smartwatches or fitness trackers with medical functions are regulated, sometimes even for specific features like Samsung's sleep apnea tools.
