The software enables something Pelago's chief technology officer, Darren Erik Vengroff, calls social discovery: using the iPhone's map and self-location features, as well as information about the prior activities of the user's friends, Whrrl proposes new places to explore or activities to try.
"If you think about your day-to-day life and how you discover things around you and places to go, to a great extent the source of that information is your friends," Vengroff says. With Whrrl, a user can "look through the eyes of friends and see the places they find compelling." The software begins with the user's position on the iPhone's map and indicates a smattering of nearby establishments. If the user's friends have visited and rated these places, the software indicates that as well. The map also shows the positions of nearby friends who have enabled a feature that lets them be seen by others.
