loving the OS but there seems to be a lack of real fitness apps and the ones that i have found that are on other platforms are missing major functions. So my question is there a running/biking/walking app that is compatible with blulink polar, or any other bluetooth heart rate monitor? I read about runtatstic the problem is thats german and they don't ship the heart rate monitor that is compatible to the united states at this time which is crazy why offer the app and all of its features but the main piece we cannot get. anyway someone thats into fitness please help we have spent countless hours i am hoping someone knows of a good app that is compatible with the heart rate monitors
