Yotemy counts down to when you need to leave, not when your plan starts. It works backward from travel time and the prep time you set, and a home-screen widget changes color as it gets close: white when there's plenty of time, green to get ready, amber if you might be late, blue on the way. Plans come in from your calendar automatically, or add them right in Yotemy. Invite someone, and their Yotemy counts down too.
