interval training apps

I have seen an app that helps with interval training. It shows a time during which high level of heart rate activity takes place followed by a period of low intensity. I am interested in finding out more about this app as I am training for cycling and do my own interval training and believe this app would help me be more efficient.

  • I am a runner and I found Ismoothrun one of the best app for running and biking. It's worth every cent
