Monica is an open-source web application to organize the interactions with your loved ones. I call it a PRM, or Personal Relationship Management. Think of it as a CRM (a popular tool used by sales teams in the corporate world) for your friends or family. This is what it currently looks like:

Monica allows people to keep track of everything that's important about their friends and family. Like the activities done with them. When you last called someone. What you talked about. It will help you remember the name and the age of the kids. It can also remind you to call someone you haven't talked to in a while.
