Foursquare Client "4th & Mayor" For WP7
"In the case of 4th & Mayor, an app that ties into location service Foursquare, there is already a native app, but that hasn't stopped Jeff Wilcox from trying to improve upon it. A year after its release, 4th & Mayor is sitting at version 3.3, and the app has been run over eight million times in that period. There have been over 7.5 million Foursquare checkins using the app, too. Wilcox says that the app is by over 60,000 people every day, with 35k enabling push notifications on their Windows Phones."
If you are a fan of the Foursquare service, which helps you find new ways to explore your city by checking in to places that you enjoy, you will want to "check out" this client app for WP7. Developer Jeff Wilcox is also intending to develop this app for Windows 8 tablets down the road.
