What I'm finding from using and talking to beta users of DidSum (referenced in another comment on this post) is that the act of physically tracking a behavior has value in building habits and improving toward goals (or being extra aware of it, when you're not).
This is doubly true in a social setting where your friends/spouse/mom/coach can _see_ when you are or are not taking actions toward what you want to improve at.
