UPDATE: 08/02/2023 10:00 EST BY ROLAND UDVARLAKI

We regularly update our buying guides to ensure it stays up-to-date and relevant. We added the new Samsung Galaxy Watch 6 series of smartwatches and made some improvements to this list.

Heart rate monitors and electrocardiogram (ECG) sensors have taken off in recent years, and most new smartwatches come equipped with both sensors. The added tracking features let you track your heart’s rhythm and electrical activity, making them excellent for tracking your health and fitness data. New smartwatches and fitness trackers can help you better understand your workouts and enable you to track your progress.


The ability to monitor your health has never been easier and more accurate than it is today. The new features let you get closer to your goals, and they’re also often used for diagnosing medical conditions.

Our list contains some of the best ECG-capable smartwatches. We included the ones that have been approved and cleared by the FDA (Food and Drug Administration), and the ones that have the hardware, but are awaiting approval. Keep in mind that devices that aren’t yet approved don’t necessarily translate into being inaccurate or outright wrong. Still, they haven’t been rigorously tested to be certified, hence why we strongly recommend looking at the approved list if you want to take health tracking seriously.

The story changes quite a lot when it comes to the Apple Watch Ultra. It’s water-resistant for up to 100m. It has additional certifications and protection to be the best smartwatch for divers, providing them with information such as a depth gauge and a water temperature sensor.
