Blendr is an easy to use Dating App that allows you to meet new people who are close to you within minutes.
Blendr uses award-winning technology and real-time functionality to unite users looking to discover new people with common pursuits and backgrounds. In addition it is a free app.
You can search and browse users by location, filter by interests, check-in to venues and see who and how many other Blendr users have checked-in. You can set up private conversations and much more.
The downside is that right now it is just for iOS devices (iPhone, iPad, iPod touch), but you can connect also via the Facebook app. This means you can access it from your computer or other mobile devices as well.
The good thing is that you can decide how much or how little of your location to reveal via the privacy settings.
