Does just what I wanted it to do

Searched for several days for an app that would just track my HR using a HR monitor. I have cycle and fitness apps that use the GPS, and when exercising, I use these but they burn the battery quite rapidly. I wanted something to just record HR whilst I was not exercising to full capacity or just walking. The bonus is that the app tracks HR zones based on heart rate. I am using a scosche HR monitor and it works well with app.
