Best Cardio Apps?

Hey Everyone,

Please recommend some good cardio health apps?
TIA,

I like Jefit. They have tons of programs already in, or you can make your own. It walks you through your workout, has a rest timer, and preloads your lifts with what you lifted last time (so you don't accidently not overload).

If you still read this, I used Map My Run in relation to My Fitness Pal.

Map My Run will map out your run and give a guesstimate of how much calories burnt. If you're looking for programs, any HIIT will work, burpees, etc.

fitbit makes some good stuff wife has one.

The Nike app is pretty legit.
