Quick Links


We have included the new Apple Watch Series 8, and the Apple Watch Ultra. We have also added that the HUAWEI Watch GT Pro 3 and HUAWEI Watch D have now been CE certified in Europe and Turkey.

Heart rate monitors and electrocardiogram (ECG) sensors took off in recent years, and most new smartwatches come equipped with both sensors. These let you track your heart’s rhythm and electrical activity, making them excellent for tracking your health and fitness data. These can help you track your progress, get you closer to your goals, and be used for diagnosing medical conditions. We also have an excellent article about the best smartwatches that work with both Android and iOS smartphones.


Our list contains some of the best ECG-capable smartwatches. We included the ones that have been approved by the FDA (Food and Drug Administration), and the ones that have the hardware, but are awaiting approval. The ones that aren’t yet approved don’t necessarily mean they’re not accurate. Still, they haven’t been rigorously tested to be certified to be used for a few things, hence why we’ll strongly recommend the approved smartwatches, if you want to take health tracking seriously.
