While these fitness trackers are not certified medical devices, over the past 18 months, we learned that SpO2 (blood oxygen) tracking was an indicator of serious symptoms of COVID-19 so these trackers can at least assist you in making informed decisions about when to see a physician. However, there is still plenty of competition available from the likes of companies such as Amazfit and Xiaomi, with one of these companies selling more fitness bands than any other company in the world. Some of these companies no longer make fitness trackers. Smartwatches can be used as a fitness tracker, but less expensive and smaller devices are available to capture much of the same data.ДЇitbit was an early pioneer in fitness tracking, and then we saw trackers available from Jawbone, Pebble, Nike, Microsoft, Samsung, Garmin, and more. However, many people don't wear a watch and still want to collect 24/7 activity data to evaluate their lifestyle and work to improve their health and wellness. The Apple Watch is arguably the best smartwatch available today. If you see inaccuracies in our content, please report the mistake via this form.
