I have heard there was a app that you used before the S Health app came along can anybody tell me what it was and I had found the location to download it but cant find the web page now, I know that you cant find it in the Samsung apps section as they have upgraded to the S Health app but I am having a error message that says "product does not exist in this store 4002" when I try to hit the "tap to see wearable device data" section on the S Health app I get that error, any help is appreciated.
