Marco Friend Locator 1.0 for iOS/Find and Meet Any Friend via Smartphone
Uncommon Projects today introduces Marco Friend Locator 1.0 for iOS, the free SMS powered app that shows the user's location on a map, along with that of any friend with a smartphone, so they can find each other easily. On launch the app displays the user's position on a street level Google Map, and they may then ask their friend's location using SMS. Connected via the Marco website, the recipient can automatically respond. Now linked, the user can see both their locations instantaneously.
