Just received Zephyr HxM Bluetooth heart rate sensor and looking for apps to use it with. By just searching "heart rate" on Market I was able to quickly locate apps that would display heart rate, and do basic training "in heart rate zone". Looking for something more advanced--interval training, preset workouts, virtual coach. Not sure if such apps exist for Android, do you know of any?
You'll find some answers in this thread on the Bicycles site: Bicycling apps for Android. (I don't have the rep here to make this a comment. Mods, please feel free to transmongrify this to a comment if you feel it's appropriate.)
