The people that brought the world MizPee, the mobile restroom tracker that helps you find a clean place when you just gotta go, launched a parent-friendly site called Yojo Mama today.

Described as a "concierge for your cell," the site helps moms and dads find child-friendly restaurants, toy stores, kids clothing stores, diaper-changing stations (can I get an amen!) and playgrounds from your computer or web enabled cell phone.

The results are based on the user's current location, neighborhood or city. I tested the site for diaper changing locations in one of my favorite San Francisco neighborhoods and received directions to a nearby public library, mall and a handful of low key restaurants. The service only works in New York and San Francisco right now, but Los Angeles, Chicago and other areas are coming soon. I suspect it will be a hit with mobile parents living in metropolitan areas and geek does too!
