There was a time when the distinction between traditional smartwatches and running watches (and multisport watches) was clear. Members of the former category were great for basic health and fitness tracking, like steps and heart rate, while one used performance wearables to track workouts.
Thanks to advancements in smartwatch, GPS and sensor technology, the lines are blurred in 2025, to say the least. Almost all smartwatches from major brands can monitor not only heart rate but also heart rate variability, blood oxygen levels, stress, sleep, and much more.
