I had to change my venu and deleted the old, I had an app I think it was something simple Like "workout" not really sure. I click the top button and select the app called "workout" and the screen allow me to select the type of workout (cardio, yoga , bike, Palaties, HIIT, etc) then start.. it had a HR zone bar graph at the bottom the moved from right to left as the workout progressed, any idea what the app might be?
