I've been using several fitness apps with Apple's health app but I'm a little concerned how well they will integrate with Watch. For instance, MyFitness pal gives me a daily budget of calories to eat based on my activity level. If the Watch is also feeding in activity information, will this be duplicated? I'm more concerned about Fitstar. Fitstar takes into account my height, weight, etc. when I do a work out and calculates how many active calories I've burned. If I'm wearing the Watch, it should also be recoding my active calories duplicating the information and messing up the MyFitness Pal calorie budget. Thoughts? Will I need to remove my Watch when using Fitstar?
