FRICKbits
FRICKbits...it's not what you think. It is a way to "take back your data and turn it into art." FRICKbits is an iPhone app that takes your GPS data makes it into map based artwork.
Since it tracks your movements including steps I am counting it as a fitness app and I do find it motivating to earn more little bits and clusters.
With this app you can be involved in the art making process as you get to pick the color palate and you can zoom in and out on the map. You can also change the artwork by selecting a date range.
Here's one of mine
