Jawbone to Fitbit...Need Help with Exercise Calories

jackslovely

I had a Jawbone Up2 for about 4 months and just last week switched to the Fitbit Alta and I'm noticing my exercise calories that the Fitbit is giving me are less than what Jawbone used to project. I usually take about 8k steps a day and after my last sync at night Jawbone would give me 600-800 in exercise calories back (i never eat back any of these, but i like seeing how much "extra" i earned for motivation to move more) and the Fitbit for the same amount of steps is giving me around 300-400.

Anyone else experience this going from one tracker to another?
