This already exists, it's called Gratafy.

put in your search criteria, and providers currently available would pop up on the map.

I have nothing on my Android phone because of the whacked privacy policies of apps in Google store.  A flashlight app that has access to your address books, GPS locations, text message files...really?

Think about all the tracking data Google Car will keep.  Where you are going, how long you are there. Where you are at any given time, who is with you.  I think I could make a mint on duplicating apps that have no tracking.

Viola... Create your own doubles partner.

You can also just use the search function in TER, which works similar to what these boys in 'Weird Science' were doing, but this looks like more fun lol.
