POLAR LOOP! Help

saruuhm

I got a polar loop yesterday from Walmart, I have an iPhone 5. I just purchased the separate HR band from a computer store and it says only compatible up to iPhone 5.... It's the HR 6 I believe. Currently this isn't a problem, but I'm worried about if I want to upgrade my phone. Does anyone know the difference between the h7 and the h6? Also, I dont do much or any cardio at the gym. I just lift, is this still a beneficial product for me? Thanks guys. Also, any tips, tricks or comments are more than needed!
