I love the Sparkpeople App and I love all the great fitness tracking apps out there. I current favorite is ENDOMONDO. Any chance Sparkpeople will include GPS fitness tracking in it's app or partner with one of the fitness tracking apps already out here so we can track our fitness live with our smartphones?
Endomondo has a great friend feed with fitness activities posted that really keeps me motivated. I'd love to be able to automatically feed fitness data into the Sparkpeople friend feed. I would find that very motivating to see what my many Sparkpeople friends are doing to stay fit as they are doing it.
