I just came back to iOS and was happy to start using the feature again with my Nike+ sensor. Was salty to reach the gym and try to pair my sensor with the iPhone 6 only to not find the option. Lucky for me I have the most recent Nano which still supports it but I'm sad to see this be phased out. All this means is that the sensors and whatnot will likely stop being made sooner than later. I've logged hundreds of miles on this.
