I have a goal of running 1,000 miles total by the end of this year. I want to be able to track that by putting in my daily runs. I could use a milestone tracker with 1,000 1 mile milestones, but why not have a tracker that adds up all the numbers you put in. Other uses: purchases. Put in the price of each of your purchases for a certain category to keep track of how much you've spent on it.
