Hello! Is anybody here using "60beat Heart Rate RX?"- - see: http://www.60beat.com/ -- it connects your HRM to your iPhone- and I'm leaning towards choosing a Polar HRM because of it's compatibility with the 60Beat & what's already in my iPhone (MFP, RunKeeper, GPS, music etc.).
Also other than the HRM that comes with EA Sports Active I don't have an actual dedicated HRM but the FT7 and FT4's user replaceable batteries seemed like the best choice and easiest to find on sale. Does anyone suggest one over the other or recommend an alternate choice? Thanks in advance, Pete
