OUT is an app that makes raising children together in the city as effortless as possible. It helps parents discover spontaneous opportunities to connect with their community - from open doors at neighbors' houses to impromptu playground meetups.

The app solves the "computational problem" of parenting social coordination by knowing:

• Where everyone is and what they're up for
• What sort of hanging out they want (energy levels, social circles)
• How to get there and the effort required
• What affordances exist for childcare at each location

• Old Pals: Effortless, energizing relationships
• Friends: Some energy required but enjoyable bonds
• New Friends: Getting-to-know-you relationships that require more energy

• Open Door: "Come over anytime" invitations
• Public Outings: Scheduled activities anyone can join
• Private Outings: Planned activities for specific circles
• Help Requests: Mutual aid opportunities
