I don't know anything about the FitBit, but I have the Sparks Activity Tracker and have been using it four days now. I really like it! I'm glad I bought it. :) I guess to become unconfused, you'll have to ask someone who has had both, but I wanted to let you know that I'm happy with the Tracker.
It's NEVER to late to get fit!!!

“What? Do you not know that your body is the temple of the Holy Ghost which is in you, which you have of God, and you are not your own? For you are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.” 1 Corinthians 6:19-20
