Question: Apple Watch: calories not counted

So I did a 25min HIIT workout, chose Calories option, set calories to 300 and away I went.

I did this on a treadmill, alternating speeds between 5mph & 9mph.

At no point or even afterwards did the calorie counter take any readings (Active Cal / Total Cal).

It remained at 0 for both.


The only thing to take a real time reading was my heart rate and time elapsed.


I have my measurement set up correctly; height, weight, etc.

I thought when the countdown started it would record my calories burnt.


Am I missing something?

Apple Watch Series 3, watchOS 4

Hi


If calories are not being recorded by the Activity app or Workout app, then the following steps may help (check after each):


If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:


Check that you have set up the Activity app:


Close certain apps and restart both your iPhone and your Apple Watch:


Check your fitness tracking settings:

  • On your iPhone, in the Watch app, go to: My Watch (tab) > Privacy - turn on Heart Rate and Fitness Tracking.
  • On your iPhone, go to: Settings > Privacy > Motion & Fitness - check that both Fitness Tracking and Health are enabled.


Check that Wrist Detection is turned on and that, if passcode is enabled, you are unlocking your Apple Watch after placing it on your wrist:

  • On your iPhone, in the Watch app, go to: My Watch (tab) > Passcode > turn Wrist Detection on.


Check that you are wearing your Apple Watch correctly:

  • For the best performance from your Apple Watch - including the most accurate readings from the heart rate sensor, which is used continually during workouts - be sure to wear your Apple Watch snugly (but not too tightly) on the top of your wrist.
  • Apple suggests tightening your Apple Watch band before workouts and loosening it again afterwards:
  • Sensor performance can be affected by skin changes, such as by some wrist tattoos.


Calibrate your Apple Watch, resetting any existing calibration data and starting afresh. Follow the instructions here (this process can be equally beneficial for Series 3 models):


If the issue persists, then it may help to unpair and re-pair your Apple Watch:


If the issue still persists, then I suggest that you contact Apple Support (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:
