Does anyone here use the app called "step counter?" I noticed that it sometimes does not update the number of steps I've taken even when I am exercising. I would understand if it does not recognize the steps I take when I am stretching because those are low impact, but when I am jogging in place or doing jumping jacks, it still does not do so. I wonder if anyone has experience with this app or if there is a better app I can try? I feel that I've used a LOT of them already like runtastic.
