I use this app to keep track of both walking and biking. It was very useful on my vacation when I set a goal of 200 miles in the month of February for walking and biking. I was close towards the end of my vacation, and only knew that because of this app. So I hit the road and was able to reach my goal before the end of the month.
I love this app!!
