I use it to log marathon training. There are a lot of fitness tracking apps out there, 2 of which I use, but it's nice seeing:

- Plan for miles run every day of the week, side-by-side with what I actually ran, notes about pace, weather, and other factors

- Sum of total weekly mileage done vs. planned, amount left to meet my goals

- Number of weeks left until race

all in one "dashboard." It's nothing fancy, but the date and sum functions made it really trivial to make a template for this exactly how I wanted it.
