Fitness app and watch record calories far in excess of what I am burning

I am an 70 year old male who is very fit for my age - 5'9" and weigh 145. I hike, ski, and "ride" an indoor bike 5 days a week, getting my heart rate up in excess of 150 beats per minute. My resting heart rate is usually in the low 50s. I have been using the Wahoo System app and a Polar heart rate monitor to track my indoor exercise and monitor calories burned and heart rate. I use the Pacer app to track my hikes and calories burned. I use the Lose It app on my phone to track daily caloric intake and expenditures. I know exactly how many calories I burn daily.


I purchased the Apple Watch Series 8 because I thought it would help me to track my calorie expenditure more easily, without the need to pull my phone out of my pocket during hikes and for skiing. I found the watch and app to provide supposed calorie burn information that has been totally ridiculous and wildly inaccurate.


Despite recalibrating and resetting the app according to Apple's instructions, I still get ridiculous readings. For example, today in the Pacer app I have recorded 1.1 miles of walking, but the app which I integrated with the phone is telling me I burned 426 calories walking. That's a ridiculous figure for a short amount of walking. The fitness app told me I burned 356 calories riding my indoor bike this morning for 53 minutes. I know this is an incorrect figure because I have data for three years of workouts and this amount of time on the bike only burns 195 calories.


I am extremely disappointed with the Apple Fitness app and will not renew my subscription to it unless I can find a fix for its inaccurate calculations.

As there is no subscription for Fitness app I presume you mean Fitness+ but yes it does seem to be far too high.

In iPhone Watch app, My Watch in Health ensure your data is completed correctly.

You can also recalibrate your Watch here

One personal point, although I am not medically qualified I have been running for 40 years. I am 71 with a resting heart rate of 49 and I would never go anywhere near 150bpm. I hope you are working with your medical adviser.

Good to know.

It may be contributing to high calories as a function of time, weight, gender, age and heart rate, but it still seems a tad too large to me.


Apple Support may well ask you to do the following, it may save time if you try now...


General bad behaviour

If all settings normal but behaviour is irrational there is a progressive hierarchy of remedies...

First force restart the Watch

i.e. press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo.

 Then, although it may seem irrelevant, while it is restarting Force Restart the paired iphone   Force restart iPhone – Apple Support (UK)

Test it for a while. If it is still misbehaving... Unpair and set up again

 Unpair and erase your Apple Watch – Apple Support (UK)

and then set up without restoring the backup

Set up your Apple Watch – Apple Support (UK)

You may also want to make sure the software on the watch and iphone are both up to date to the same level. Updates are in pairs.

Thank you for your suggestions. Yes, my data is completed correctly. I've checked that a couple of times. Yes, I have recalibrated the watch. I'll try contacting Apple support to see if they have someone more knowledgable to the person I spoke with the first time. And, yes I had a treadmill test with a cardiologist and smoked it. The doctor said there was no problem with getting my heart rate up that high. My personal physician also concurred.

Thank you for your very detailed recommendations. I will definitely try your suggestions over the next couple of days. It appears as though the watch really messed up the Pacer app on my phone, and a contributing factor might have been the fact I also had the Pedometer app on my phone. I deleted Pedometer and now Pacer appears to be giving me the correct caloric expenditure for my walking activity.


I appreciate your help!
