>Gears and Wears>Android app with realtime heart rate zone audio cues?
I'm looking for an app that would give me an immediate sound cue when I go over or under my designated heart rate zone. That's it! That's all I need out of the app: that I can input a range (say 150-165 bpm) and it would alert me with sound if I go below 150 or over 165, as quickly as possible. Is there an app that does this, and preferably very little else?
