Fitocracy's great as well! But they're more centered in tracking and gamifying.

We take a different "just tell me what to do" approach. Users sign up, enter their stats and choose a goal: strength, weight loss, etc. With that, we generate workouts and plans to help them get there.

We also offer meal plans and personal coaching, because the human aspect matters a lot. That's why I believe most "fitness tracking" startups will fail... people are looking for a plan, not for a pretty dashboard.
