It keeps track of my daily progress and I can see if I'm on track with the previous months.  It also has a GPS, so I can see my routes.  I like to think of it as a way of giving myself credit for work put in, it even keeps track of my lifetime stats, from the date that I began using the app. There are other ways to use technology to help your fitness goals. Another thing I like are podcasts of running music set to a certain BPM that I download from itunes.  There are tons of podcasts available for download that you can use for working out.  There are some models of treadmills that are programmed to mimick terrain of locations around the world so the ramp moves up or down according to that location. It helps break up the monotony of being on a treadmill.  These are just a few of the things I could come with off the top of my head, but there are a lot of uses for technology in fitness.
