GeoSD is a native iOS application that allows San Diego residents and visitors to use their iPhone to easily locate city, county and state services near their current location.
The application can find nearby DMV offices (and automatically look up current wait times), nearby hospitals, fire/police stations, libraries, schools, etc.
Using the user's current location, the application can find the nearest transit stops and show upcoming departures of public transportation from those stops. San Diego MTS buses/trolleys and the North County Transit District Breeze, Coaster, and Sprinter are all supported. Even the Coronado Ferry is supported.
The application can also find nearby registered sex offenders and tweets with nearby geolocation tags.
