Wheretheladies.at, a web app that aggregates Foursquare checkins by the female gender, is now available on the iPhone. The where the ladies at app for iPhone, iPod touch, and iPad ranks nearby locations by the number of females who have checked in (using a dictionary crawl and permutation logic when gender isn't available), and is also a compass pointing to the venue with the most ladies. Done by the fine gents at http://wheretheladies.at. It could be a bar it could be a cafe, who knows!
Wheretheladies.at only counts check-ins with in the past 30 minutes to ensure that ladies will be there when you arrive, "When it says 10 ladies are at Elbo Room that means in the last ~30min. I think that is key. It's about where to head to right now."
