Looks like finding 'the one' is just not enough for some greedy Irish folk...  It seems more than 10,000 Irish people are more interested in finding "the two". This is how many have reportedly signed up for the new app, called 3nder (pronounced Thrinder), which works exactly like Tinder except that it has been designed to specifically cater for those are looking for a threesome. According to the Irish Mirror, the London-based startup, whose slogan is "kink different" has gone down a storm stateside and now looks like it is going to popular on this side of the pond, too. The app description explains: "It's about feeling comfortable with your curiosity about sexuality. Get your lovely matches and start exchanging photos and messages." According to its founder, Dimo Trifonov, 3nder allows you to "date kinky, curious and openminded singles and couples around you, whether you are “straight, bisexual, gay, poly- or pansexual”. Speaking to the Irish Sun, he said: "We have around 10,000 users in Ireland but hope to hit at least 500,000 once the Android app is out. "Android makes 85% of the mobile market." The biggest difference, from what we can tell, is that you can start group chats once you've matched with people, allowing you to create a "team" so to speak. With four million swipes a month, it looks like three really is the magic number.
