RunKeeper updated its Fitness Reports to provide more information. A premium account (RunKeeper Elite) is needed to view most of it. However, I found the the Total Distance information available for free accounts useful. It lets me look at my walking information in a variety of ways. You can see my totals sorted by day of week in the screenshot above.

The free RunKeeper mobile app is available for a variety of platforms. I use the version for Windows Phone to track my near-daily walking sessions.
