My question for anyone out there: is there a way to keep the HRM on display the whole time i'm working out. I can see it and then I'm guessing the Vivosmart goes to sleep but I want to be able to glance at where my heart rate is at without having to double tap my device. Just got this dang thing and feeling like I want to return it but I know it will take time to get used to how things are done as it doesn't seem intuitive.
