A colleague of mine recently let me know about Brandon Nolte‘s free Android App called Phone Tracks.  The application is designed to help the user stay connected to five contacts via telephone on a consistent basis.  After selecting a contact and how frequently you plan to call, Phone Tracks lets you know how long it has been since your last 2-minute conversation with that individual via color-coded notification.  It is an interesting way to leverage technology to build relationships.  Let me know what you think.
