Why are the first 2,500 steps not deducted with Apple Watch data?

Both the Nutracheck app and Apple Watch use calculations to deduct BMR (basal metabolic rate) calories from your exercise figures. Our system does this by only counting calories burned once you've exceeded 2,500 steps, whereas Apple uses an algorithm in the background to deduct BMR calories automatically before giving you a total active energy figure.

We believe the active energy figure provided by Apple Watch is the most accurate way to record calories burned, so the figure in the Nutracheck app will match what it says on your Watch.

However, members who don't have an Apple Watch and sync with the iPhone's motion sensor, the calorie burn for steps is calculated using the Nutracheck formula i.e. only steps over 2,500 are counted.
