BetterFriend is a memory for the people in your life.
You are not bad at this. Nobody holds every birthday, every "how did the interview go?" and every friend they meant to call in one head. So BetterFriend holds them instead: who is in your life, what they told you, and how many days it's been since you last spoke. It tells you when someone has been waiting a while, and hands you your own note from last time, so you know exactly where to pick up.
