Start-up weekends are crazy.
Spending a weekend with a bunch of strangers and working your ass off on a product is a crazy thing but I'm glad that I went. Going to start-up weekend is the reason why I started my own business.
Wingman was pitched as an app that helps guys be better with thier relationships. You set up reminders about anniversaries, to text your best friend, or call your mom. You could also set up profiles of likes and dislikes for the people in your life and automatically send them gifts from local businesses right from your phone.
