Fitness App Caloric Burn

The Fitness App grossly underestimates my caloric burn during bike rides. Just returned from a 17-mile trail ride and the app reported 600 calories burned. WahooFitness and RideWithGPS both reported over 1,060 calories burned. Adding to the mystery, the Fitness App reported 170 calories were burned during "Resting" but the ride was non-stop. Would loss of GPS signal riding through heavily forested areas cause the app to think I had stopped? Even though my heart continued to pound at an average rate of 136 bpm?

Hello JF,


My experience is the same as yours.


For example, I did a run yesterday, using Outdoor Cycle on my Watch Workout: 154 Active calories, 206 Resting calories, 360 Total; 266 passed on to the Health app; 535 as recorded on a chest strap feeding in to Wahoo Fitness app. This is typical for me; and from the various postings to this forum, it's safe to say it's common to many people.


Three of the four Apple Support people whom I have contacted trying to sort this out have told me that yes, there are known problems with the Workout - Health software and connection; one came out straight with a comment that the reason I get the message 'No Data' on the Resting calories pane of the Health app is that it's borked. But all have assured me that the problem is being worked on.


So, for the time being, don't trust the Watch or the Health app. 'Ne confidite in pupillam', as the Romans say in their Forum.


Hello Lexion,


These figures are the first part of the test I said I'd do, seeing if using another variant of Workout, e.g. Other, would make a difference to the figures recorded on the same run. Unfuriatingly my Wahoo chest sensor has packed in!!! As soon as its replacement arrives I'll complete the test.


Byeee

Corrinel, DMM....


... that post of mine dated 19th June related to the Watch calorie counts using OS1, and is obsolete now that we have OS2. (Though it was written after I'd done the VO2max calibration, so that wasn't the issue.)


Anyway, Apple have now fixed their borked Passive Cals counter, which wouldn't register on the iPhone at all even tho' the Watch was generating a reading that was separate from Active Cals. Now, under OS2, we have Resting Energy and Active Energy respectively, displaying on the Watch.


I still don't trust some of the readings though. Some workouts (cycling, runs, walks etc) seem fine but others are very inaccurate compared to a chest strap arrangement of the kind you recommend, Corrinel, I agree.


Apple should thank the techies very much developing their super software, and updating it, and shoo them away back to their labs while they employ an experienced medical/fitness writer to prepare a careful account of how to calibrate, use AND INTERPRET the different workout outputs of the Watch once they'e shown up on the Health app of the iPhone. The publicity descriptions on the web-site aren't much use.


I don't have a problem with battery drain though: a 90-minute gym workout, a 4-km cycle ride there and back, and the morning's normal watch usage... it's 6pm now and I still have 61% battery level. Are you perhaps running more than the single, Polar Beat app on your iPhone?
