Any good fitness apps (for android + iPhone)?

I've been working my way back to the gym slowly but surely. I've been doing classes, but when I can't make those I use the GAIN fitness iPhone app to plan my workouts (I really like it because it will modify the workout for where I am: gym or home). My mom asked if I wanted to try a new workout with her, pointing to the 100 Pushups app. I was wondering if there's something like GAIN that focuses on a full body workout (instead of just pushups) that I can use with my iPhone and my mom can join with her Android. I know there's Teemo, but that's still for iPhone alone. Any ideas ladies?
