The Fit Bit will record steps, calories burned, and acts as a clock. It has software that connects to the Fit Bit website and it will track your calories and activities. I have one and really like it. There are newer versions now than the one I have. Take a look at my article: Fit Bit Review in the review category on my main Exercise Site page.
I have also used an online tool called "Fit Day". I have used it often and really like it. It is free unless you want to upgrade to the premium version.
