HRM users, do you use an app to track your HR and calorie burn? I have two HRM straps, one is a Polar that uses a watch and another is a Wahoo bluetooth model that syncs with my iphone. I love the bluetooth one because it works well with Runkeeper, the app I use for running and biking. However I don't have an app for my circuit training. I can monitor my HR with my timer app but not my calorie burn. Suggestions?
