Got a parking spot in San Francisco? You can rent it out when you're out!

If you're tired of losing 30 minutes of your life to the parking-space hunt every time you go out, this is the App for you. What if your friends living downtown said you could park in their driveway while they were at work or gone for the weekend, as long as you were out by an agreed time?

Park Circa connects people who have empty parking spaces during a set time to people that need them. We enable coordination between neighbors and friends, so that your community resources are optimized for everyone's benefit. We help organize and publish parking schedules and we facilitate payment between parties, so that people can find parking when they need it and where they need it. Drivers find a place to park, and space owners make some money on their empty driveways. Everyone wins.

Currently, iPhone only (Android and Blackberry coming soon)
