CT does have some online support, but I haven't really looked into it:
It is also connected to google health and uses my gmail account... Guess I should look at it sometime. I know you can pay for a separate app to race with others. I am still using the free version of CT, at $10 for the full version I wanted to make sure I would like it first. It is also integrated with the Calorific App, but I didn't care for that one.
