I live in a small university town. All the students go home on the weekend. The only transport available is bus, but its expensive and inconvenient. I want to create an app, where people will share rides. 2 buttons "ride offer" and "ride search". In ride offer a person will offer ride, give time, price and number of seats available. In ride search people will look for rides and buy seats. All the transactions are through the phone and app. I keep 10%. In the end people will rank each other. I also want it to be integrated with FB, so a person could "invite friends". Thats it.
