I have been tracking data for a few months now, and there is one thing that is really frustrating me - variable outcomes.
On my phone I have Argus, Withings and MyFitnessPal, and they are all configured to ‘talk’ to each other. I use a Withings Pulse in conjunction with the app.
Argus and the Pulse both track my step count. They are always different by about 10%, but I can accept that this is a reasonable variation over the course of a day, especially as I am a fairly active person (I average around 18-20,000 steps per day).
What I find harder to understand is the HUGE variation in calories burned. At the moment the three apps are reporting the following calorie burn for today:
Argus: 1758
Withings: 2414
MyFitnessPal: 1247
The really weird thing is that MyFitnessPal gets its data from Withings!
Can anyone explain the discrepancy to me? I tend to think that maybe Withings includes my BMR, but even if that is true the figures still vary by as much as 50% on any given day.
