Here are a few data points I’ve got over the past week with both devices worn on the same wrist close to 24hours a day:

As you can see there is still no consensus on what constitutes a step and how you calculate calorie expenditure.
Up24 is a newer device and also includes a sleep tracker to maybe has more advanced math, but there is no way for me to claim which one is more accurate. Both devices accomplished one thing well – giving me instant feedback on when I am active and making me feel good about moving around during the day.
