Favorite heart rate app to use with bluetooth chest strap – Heart Graph Review

I needed an app that would display the heart rate being measured with my chest strap HR monitor and also the history of it across my workout. Used the free version for about 4 months and it was great! I would leave my phone on the treadmill to make sure I was staying in HR zone 2 while I was in base building season. Ive used it to compare the HR monitored from my fitbit wrist watch and last month I went ahead and bought the paid version so I could see calories burned and compare it to what fitbit was calculating. Love this app!
