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 - see all your activities
• Friends: Some energy required but enjoyable bonds - see friend and old pal activities
• New Friends: Getting-to-know-you relationships - see activities targeted to all circles

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

• Distance-based filtering: Only see activities within reasonable travel time
• Transport optimization: Calculates best travel mode (walk, bike, transit, car)
• Social targeting: Only see activities from people in your circles
• Natural language: "Go to Bob's place (5 min bike ride)"

• Add friends: Search and add other users to your network
• Manage circles: Move friends between old pals, friends, and new friends
• Visual interface: See all your social connections organized by intimacy level
