Today I really walked a lot (to reach the 5000 minimum activity count). The positive affect that this app has is that I prefer now to walk to a college's office, to talk in person, instead of writing a mail. :D And I went for a walk in my lunch break instead of staying at the computer. After work we went to the park and that's it. Only walking. I'm just a bit sad that my daily pushups don't really count much.
