Maximise your experience with AXTRO Fit 3!

You have most likely landed here after getting your hands on our newly launched AXTRO Fit 3 or currently might even be setting up your tracker to get moving and win exciting incentives. Whatever the case, we can't wait for you to start living a healthy lifestyle with AXTRO Fit 3!

So, following the much-anticipated product launch, you have finally received our fitness tracker, which has been the talk of the town for several months now. What’s next? Even if you are eager to get moving, you will still need to learn about the many functions to get the most out of your AXTRO Fit 3 and set it up so that it runs smoothly throughout your physical activities.


The all-new AXTRO Fit 3 provides awesome features that adds value to your day without burning a hole in your pocket. What’s new compared to previous seasons’ tracker? It has features like blood oxygen (SpO) and sleep tracking (for eligible participants). To check if you are eligible for the sleep tracking feature and for more information on the Sleep Challenge, please visit:

Before we dive into more details on the new and intriguing SpO tracking feature, let us first walk you through how to use the basic functions of AXTRO Fit 3.

Basic Functions

  • Switching On: To begin, press and hold the touch button for at least 8 seconds.

  • Changing Watch Face: To change the watch face, press and hold for at least 5 seconds.

  • Switching Off: To turn off the device, tap the touch button to power off.

  • Charging: We recommend charging your tracker only when it is running low to prevent your battery performance from deteriorating in the long run.

    The charging duration is approximately 2 hours. When charging, ensure that the charging contact points of your tracker and the magnetic cradle are aligned.

    *During manufacturing, the AXTRO Fit 3 tracker is set to hibernation mode to prevent the battery from draining too quickly.

Measuring SpO₂

The SpO₂ tracking feature of AXTRO Fit 3 is simple to use and can be measured in just a few steps. Isn't that amazing? To start measuring your blood oxygen:

  1. Tap the touch button until you see the Blood Oxygen screen.
  2. Long press and hold for at least 3 seconds to start the SpO measurement.
  3. Your blood oxygen reading should show within 1-2 minutes.
  4. To exit the blood oxygen measurement page, press and hold the touch button.

While measuring your blood oxygen level, keep seated and still, and wear the fitness tracker firmly above your wrist to get accurate SpO readings. Two fingers' width above the wrist bone is a good gauge. If your tracker fails to detect your blood oxygen level, repeat the above steps to try again.

Workout Modes

How to track my heart-rate with workout mode?

AXTRO Fit 3 simplifies your life by automatically monitoring your heart rate as long as it is turned on, has enough battery, and is worn properly on the wrist! If you want to see your heart rate in real time, though, follow these steps to activate ‘Workout Mode’:

  1. Tap the touch button until you see the Workout screen.
  2. Tap and hold to view the list of workout modes available.
  3. Tap to toggle between the 4 different workout modes: Walking, Running, Cycling, Others.
  4. Tap to switch between the screens.
  5. Press and hold to begin the workout of your choice.

Heart-Rate Range

Track your heart-rate to identify which tier your workout falls under using this table:

Light Moderate Vigorous 
57% - 63%
of Maximum Heart-Rate
64% - 75%
of Maximum Heart-Rate
76% - 95%
of Maximum Heart-Rate

How to stop workout mode?

  1.  Press and hold the touch button again.
  2. Tap to confirm the end of your workout session.
  3. Your workout summary will be displayed on the screen.
  4. To exit, press and hold again.

Now, here is where you might have some questions. “Will my tracker still track my heart-rate after I end my workout session?”, “Does workout mode drain my battery?” As mentioned previously, your tracker will always monitor your heart rate when it is turned on. So, fret not! Battery wise, unfortunately, it will drain out when you stay on it for extended periods of time. Hence, we recommend using workout mode to track your heart-rate at regular intervals.

Changing Strap

This part is for you if you bought a new strap to replace your current strap, but are afraid you will mess it up and damage your watch. Follow these steps carefully to replace your strap easily!

  1.  Place your tracker facing down on a flat surface.
  2. Push the latch to the right to release the strap
  3. To insert your new strap, follow the previous step in reverse.
  4. Ensure that the strap pins are securely in place.

There you go! Spare yourself the trip to our store to get it replaced by us and do it yourself instead! It's as simple as 1, 2, and 3.

      Hi there,

      The screen of my dad’s Tempo4C watch seems to have spoilt. When the screen is tapped on at the said button, the screen doesn’t turn on.

      I am thinking of just getting a replacement for him from your shop. Can he replace it as the tracker in his Healthy 365? Or may I get the screen replaced?

      Thank you,

      Bee Kuen - January 18, 2023

      I do other workout such as cycling and swimming daily instead of walking. Can i sync the Workout accumulated under the Workout mode to MVPA? Ideally wee should take other exercise into consideration apart from steps.
