Fitness Tracker Buying Guide for Treadmill Run Tracking 2021

Best Fitness tracker for Treadmill running

Are you the one who switched to treadmill running during the COVID-19 pandemic? Are you looking for a fitness tracker or smartwatch for tracking treadmill running? To help you choose the suitable activity tracker to track your treadmill running, I have come up with a list of the best fitness tracker for treadmill.

Remember, all fitness trackers and smartwatches do not track your indoor running accurately unless it has a treadmill mode. So, it is essential to make sure that the smartwatch or fitness tracker you will buy has a built-in treadmill activity tracking mode. 

Why do you need a Fitness Tracker while running on a treadmill? 

A treadmill with a heart rate monitor detects your heart rate when you hold on to its bar or through the chest strap. However, this is not the correct method to track your heart rate while running on a treadmill.  

On the other hand, having an activity tracker that tracks indoor running has multiple benefits over other devices you use to track treadmill activity.  

  1. You can keep all your fitness data on a single platform. You do not need to keep a separate record for the treadmill. 
  2. There is no need to use any separate (wired or wireless) device to track your body metrics such as heart rate, blood oxygen (SpO2), calorie burned, etc.  
  3. Suppose you are not using an advanced treadmill. In that case, a smartwatch or fitness tracker can tell you the quality of your workout by measuring critical running metrics such as cadence, symmetry, Vertical Oscillation and much more.  

Most fitness trackers under $100-150 dollars come with all the necessary features to track the treadmill running.

Fitness Tracker Buying Guide for Treadmill Run Tracking 

If you are looking for a treadmill fitness tracker, you must keep the following points in mind. This will help you in choosing the best product based on your needs.  

Design and Build 

The first thing that you consider while selecting a fitness tracker or smartwatch is its style and built.  


Display Size and type is another crucial factor that you should consider while buying a fitness tracker. The latest fitness trackers and smartwatches come with an AMOLED touchscreen display. Fitness trackers with AMOLED display consume less power and have clear visibility, even in outdoor environments.  


Music control or storage is an essential feature that you should consider when buying a fitness tracker. So, you can control your smartphone music right from your wrist without grabbing the smartphone. 

GPS is another feature that you should consider if you are also interested in outdoor activities. Fitness Tracker like Fitbit Charge 4 tracks your route, pace and distance travelled without a phone with the help of its built-in GPS.

Even if it cost you more than any other fitness trackers mentioned here, it is the most advanced fitness tracker available in the market today.  


You must also look for battery specifications for the battery life of your fitness tracker. You must choose a fitness tracker that gives a battery back-up for at least five hours for an uninterrupted workout section. 

Also, you should remember to choose a fitness tracker with a USB Charging port if you do not want to carry your charger every time.

Most of the latest fitness trackers and Fitbit bands are coming with a USB charging port so that you can charge the device by connecting it to your laptop or power bank. 


Make sure you are buying a fitness tracker that is compatible with your smartphone. Some fitness trackers work only either with Android or iPhone.

For instance, the Honor Band 6 is compatible with Android devices only. So, you should not buy this activity tracker if you are currently using an iPhone.  

To avoid this mistake, make sure that the device you are going to purchase is compatible with your smartphone.  


It is essential to consider your budget before you buy a fitness tracker or smartwatch. Make sure you are purchasing a fitness tracker that does not create a hole in your pocket.
