Activity Tracker help please

I bought a Fitbit this weekend, but my company won't allow me to download the software on my laptop to activate it (boo!). Can anyone recommend a similar device to track calorie burn, step, etc. without having to download software? I'm not concerned with syncing the info, just viewing it and I prefer not to wear a band around my chest. Am I asking too much or does such an activity tracker exist? Thanks!
