Fitness Apps?

Pseudocyber

I really like the apps - they give me data and feedback that help me set goals and meet them.

I'm looking for an exercise app - body weight exercises (like pushups), free weight (dumbells, barbells), and maybe even weight machines.

I'm using Runkeeper for walking/running, Myfitnesspal of course, and Withings app & body scale.

Is there an exercise app (not running/walking) - that can track reps & sets, provide how to guidance, and link data to myfitnesspal and maybe some of the others?

Thanks,

PC
