7 Best Health Tracking Smartwatches in 2021(ECG, B.P, SpO2, and Many More)

Best Health Tracking Smartwatches

Now smartwatches are not for just heart rate tracking or calorie tracking. Today’s health watches and fitness trackers can track complex health metrics (vital signs) such as ECG, Blood pressure, ECG, and much more.

Fortunately, most of these devices are clinically validated for their accuracy and effectiveness.

To help you choose suitable health watches, I have compiled a list of health tracking smartwatches to track two or more health metrics, such as

  1. Heart Rate: Some watches in this list even alert you in case of an irregular heart rate.
  2. Electrocardiogram (ECG/EKG): Take an ECG right from your wrist and alert you in case of irregular heart rhythm such as atrial fibrillation. It can share your ECG report with your doctor as a PDF document
  3. Blood Oxygen Level Monitoring: Most of the health tracking watches discussed here comes with a blood oxygen sensor to track SpO2
  4. Blood Pressure: This list of best health tracking smartwatches also includes health watch for blood pressure monitoring
  5. Calories burned and much more

1. Samsung Galaxy Watch 3: (HR, ECG, SpO2, & B.P)

Samsung Galaxy Watch 3

Since the day it was released, we have been a great fan of the Samsung Galaxy Watch3, and we included it in our list of best smartwatches. It is a complete package of essential health tracking fitness and smart features. 

Back to health tracking features, you only required only this smartwatch to track all critical vital signs such as ECG, heart rate, blood oxygen (SpO2), blood pressure, sleep, calories burned, and much more.

The FDA Approved ECG app on Samsung Galaxy Watch 3 can measure ECG on-demand and spot irregularities on the ECG (irregular heart rate and atrial fibrillation).

At this point, you cannot find a smartwatch that comes with all these features. This makes it one of the top rivals to Apple Watch Series 6 and Fitbit Sense. 

Fall detection and emergency SOS are other life-saving features on this health watch. In case the wearer does not respond after a fall, it calls the Emergency department for help. 

Still not finished! It can give you a deep insight into your sleep pattern and can even detect sleep apnea with the help of its SpO2 sensor. 

It can track many indoor and outdoor activities with its advanced sensors when it comes to activity tracking.

If you have this fitness watch, then you can leave your phone at home. It can do almost everything that that a smartphone does. 

You can store and play music on the go with this smartwatch. Samsung Pay allows you to pay for a coffee on the go. If you use Galaxy Watch 3 with LTE connectivity, you can make calls or send SMS right from your smartwatch. 

One more reason for our love for Samsung wearables is that it always sends updates and improvements for its watches. For example, a recent O.S. update brings a few Galaxy Watch 3 features to its older models, such as Galaxy Watch and Galaxy Active.

The Fitbit Sense also has a built-in fall GPS to track the real-time location. However, it does not have a fall detection feature like Apple Watches and Samsung Galaxy wearables. 

Fall detection is an essential feature on a smartwatch that costs more than $300. This is the main reason why it falls behind its rivals.

If you already own a Galaxy Watch 3, I don’t suggest you upgrade to Galaxy Watch 4. On the other hand, if you are a Fitbit Charge 4 or Versa 3 owner, Charge 5 is really a massive upgrade.
